INSTALLING THE NEW STRUT ASSEMBLY1. Prior to installing the strut, attach the air fitting (21851) provided to the threaded port at

the top of the air spring (fig. 7). Seal with Teflon tape.

2. Apply Teflon tape or thread sealant to the fitting threads and install into the top of the air spring. Thread fitting in hand tight and torque 1-3/4 turns beyond hand tight.

3. Before inserting the new strut assembly, look at the top of the supplied upper mount. Left and right struts are indicated on this mount with either a large “R” or “L” along with an arrow. This arrow must point toward the front of the vehicle (fig. 8). Insert the appropriate strut into the pocket, align the upper bracket with the arrow pointing to the front of the vehicle, and reinstall the upper mount nuts. Torque to 44 Nm (33 ft./lbs.).

4. Install lower mounting bolts. Torque to 240 Nm (177 ft./lbs.).

5. Reattach the speed sensor and brake line to the tab. Use the supplied bolt (17175), washers (18444) and nyloc nut (18425), to securely attach through the lower hole of the tab.

6. Reattach the swaybar link. Torque to 74 Nm (55 ft./lbs.).

7. Install the left and right cowl, snapping the center section together. Insert the push-pins through the cowl into the body. Reattach the cowl seat.

8. Take the wiper arms and align with the previous mounting mark. Securely fasten the wiper arms in place and clip the wiper caps back on.

9. Install wheel and torque to 103 Nm (76 ft./lbs.).

ALIGNING THE VEHICLE1. Using the control system, set the vehicle height to the new custom ride height.

2. If the custom ride height is lower than stock, we recommend loosening all pivot points (bolts, nuts) on any control arm, strut arm or radius rod that contains bushings. Once they have been loosened, re-torque to stock specifications (fig. 9).

It may be necessary to cycle the suspension to loosen the bushing up from its mount. This will help re-orient the bushing at its new position based on the custom ride height.

CAUTION

Before operating1. Some struts for this vehicle come with a nine-position damping dial for added adjustability

(fi g. 14). If not, proceed to 2.

Before driving your vehicle, set the new struts to their highest setting by turning the black dial on the shaft of the strut as far as it will go to the right (position 9).

2. Next, completely defl ate and reinfl ate the air bags 2-3 times. This procedure will purge any trapped air in the dampers and allow for maximum performance. For ride performance and the most versatility, Lifestyle recommends setting the strut dial (if equipped) to position 6 or higher.

MAkE SURE THE FRONT WHEELS ARE STRAIGHT WHEN DEFLATING AND REINFLATING AIR BAGS.

issues. With the air springs deflated, check clearances on everything so as not to pinch brake lines, vent tubes, etc. Clear lines if necessary.

4. Inflate the air springs to 75PSI - 90PSI and check all connections for leaks.

5. Air Lift part #27741 or #27630, High Performance 4 Path Air Management System, is highly recommended for this product.

6. Please continue by reading the Product Use, Maintenance and Servicing section.

Technician’s Signature _________________________________

Date _________________

Clearance test — Inflate the air springs to 75-90 PSI and make sure there is at least ½” clearance from anything that might rub against each sleeve. Be sure to check the tire, brake drum, frame, shock absorbers and brake cables.

Leak test before road test — Inflate the air springs to 75PSI - 90PSI and check all connections for leaks. All leaks must be eliminated before the vehicle is road tested.

Heat test — Be sure there is sufficient clearance from heat sources, at least 6” for air springs and air lines. If a heat shield was included in the kit, install it. If there is no heat shield, but one is required, call Air Lift customer service at (800) 248-0892.

Fastener test — Recheck all bolts for proper torque.

Road test — The vehicle should be road tested after the preceding tests. Inflate the springs to recommended driving pressures. Drive the vehicle 10 miles and recheck for clearance, loose fasteners and air leaks.

Operating instructions — If professionally installed, the installer should review the operating instructions with the owner. Be sure to provide the owner with all of the paperwork that came with the kit.

INSTALLATION CHECKLIST

Overnight leak down test — Recheck air pressure after the vehicle has been used for 24 hours. If the pressure has dropped more than 5 PSI, then there is a leak that must be fixed. Either fix the leak yourself or return to the installer for service.

Air pressure requirements — I understand the air pressure requirements of my air spring system. Regardless of load, the air pressure should always be adjusted to maintain adequate ride height at all times while driving.

Thirty day or 500 mile test — I understand that I must recheck the air spring system after 30 days or 500 miles, whichever comes first. If any part shows signs of rubbing or abrasion, the source should be identified and moved, if possible. If it is not possible to relocate the cause of the abrasion, the air spring may need to be remounted. If professionally installed, the installer should be consulted. Check all fasteners for tightness.

POST-INSTALLATION CHECKLIST

MAINTENANCE GUIDELINESBy following these steps, vehicle owners will obtain the longest life and best results from their air spring.

1. Check the air pressure before driving.

2. Never inflate beyond 125 PSI.

3. If you develop an air leak in the system, use a soapy water solution to check all air line connections, before deflating and removing the spring.

4. When increasing load, always adjust the air pressure to maintain normal ride height. Increase or decrease pressure from the system as necessary to attain normal ride height for optimal ride and handling. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle.

FOR YOUR SAFETY AND TO PREVENT DAMAGE TO YOUR VEHICLE, DO NOT EXCEED MAXIMUM GROSS VEHICLE WEIGHT RATING (GVWR), AS INDICATED BY THE VEHICLE MANUFACTURER. ALTHOUGH YOUR AIR SPRINGS ARE RATED AT A MAXIMUM INFLATION PRESSURE OF 125 PSI, THE AIR PRESSURE ACTUALLY NEEDED IS DEPENDENT ON YOUR LOAD.

5. Always add air to the springs in small quantities, checking the pressure frequently. Sleeves require less air volume than a tire and inflate quickly.

6. Should it become necessary to raise the vehicle by the frame, make sure the control system is turned off before lifting.

NOTE

CAUTION

troubleshooting Guide1. Leak test the air line connections, the threaded connection into the air spring, and all fittings

in the control system.

2. Inspect the air lines to be sure none are pinched. Tie straps may be too tight. Loosen or replace the strap and replace leaking components.

3. Inspect the air line for holes and cracks. Replace as needed.

4. Look for a kink or fold in the air line. Reroute as needed.

If the preceding steps do not solve the problem, it is possibly caused by a failed air spring — either a factory defect or an operating problem. Please call Air Lift at (800) 248-0892 for assistance.

Frequently asked QuestionsQ . Will installing air springs increase the weight ratings of a vehicle? No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR)

of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty.

Q . How long should air springs last? If the air springs are properly installed and maintained they can last indefinitely.

Q . Will raising the vehicle on a hoist for service work damage the air springs? No. The vehicle can be lifted on a hoist for short-term service work such as tire rotation

or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off of the air springs.

Pressure determination comes down to three things — level vehicle, ride comfort, and stability.

1 . Level vehicle If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side,

then it is not level. Raise the air pressure to correct either of these problems and level the vehicle.

2 . Ride comfort If the vehicle has a rough or harsh ride it may be due to either too much pressure or not

enough. Try different pressures to determine the best ride comfort. See Air Lift suggested driving air pressure.

3 . Stability Stability translates into safety and should be the priority, meaning the driver may need

to sacrifice a perfectly level and comfortable ride. Stability issues include roll control, bounce, dive during braking and sponginess. Tuning out these problems usually requires additional air pressure, strut damping, or both.

tuning the air Pressure

1. If there is a problem with a swivel fitting:

a. Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting and pulling firmly on the air line. Trim 1” off the end of the air line. Be sure the cut is clean and square (see fig. 15). Reinsert the air line into the push-to-connect fitting.

Fixing leaks

1. Inflate the air spring to 80 PSI.

2. Spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and 4/5 water. Spot leaks easily by looking for bubbles in the soapy water.

3. After the test, deflate the springs to the minimum pressure required to restore the system to normal ride height.

4. Check the air pressure again after 24 hours. A 2 - 4 PSI loss after initial installation is normal. Retest for leaks if the loss is more than 5 lbs.

ALIGNING THE VEHICLE1. Using the control system, set the vehicle height to the new custom ride height.

2. If the new custom ride height is lower than stock, we recommend loosening all pivot points (bolts, nuts) on any control arm, strut arm or radius rod that contains bushings. Once they have been loosened, re-torque to stock specifications (fig. 6).

It may be necessary to cycle the suspension to loosen the bushing up from its mount. This will help re-orient the bushing at its new position based on the custom ride height.

1. Some struts for this vehicle come with a nine-position damping dial for added adjustability (fi g. 7). If not, proceed to 2.

Before driving your vehicle, set the new struts to their highest setting by turning the black dial on the shaft of the strut as far as it will go to the right (position 9).

2. Next, completely defl ate and reinfl ate the air bags 2-3 times. This procedure will purge any trapped air in the dampers and allow for maximum performance. For ride performance and the most versatility, Lifestyle recommends setting the strut dial (if equipped) to position 6 or higher.

MAkE SURE THE FRONT WHEELS ARE STRAIGHT WHEN DEFLATING AND REINFLATING AIR BAGS.

3. Infl ate and defl ate the system (do not exceed 125 PSI) to check for clearance or binding issues. With the air springs defl ated, check clearances on everything so as not to pinch brake lines, vent tubes, etc. Clear lines if necessary.

4. Infl ate the air springs to 75PSI - 90PSI and check all connections for leaks.

5. Air Lift part #27741 or #27630, High Performance 4 Path Air Management System, is highly recommended for this product.

Technician’s Signature _________________________________

Date _________________

Clearance test — Inflate the air springs to 75-90 PSI and make sure there is at least ½” clearance from anything that might rub against each sleeve. Be sure to check the tire, brake drum, frame, shock absorbers and brake cables.

Leak test before road test — Inflate the air springs to 75PSI - 90PSI and check all connections for leaks. All leaks must be eliminated before the vehicle is road tested.

Heat test — Be sure there is sufficient clearance from heat sources, at least 6” for air springs and air lines. If a heat shield was included in the kit, install it. If there is no heat shield, but one is required, call Air Lift customer service at (800) 248-0892.

Fastener test — Recheck all bolts for proper torque.

Road test — The vehicle should be road tested after the preceding tests. Inflate the springs to recommended driving pressures. Drive the vehicle 10 miles and recheck for clearance, loose fasteners and air leaks.

Operating instructions — If professionally installed, the installer should review the operating instructions with the owner. Be sure to provide the owner with all of the paperwork that came with the kit.

INSTALLATION CHECKLIST

Overnight leak down test — Recheck air pressure after the vehicle has been used for 24 hours. If the pressure has dropped more than 5 PSI, then there is a leak that must be fixed. Either fix the leak yourself or return to the installer for service.

Air pressure requirements — I understand the air pressure requirements of my air spring system. Regardless of load, the air pressure should always be adjusted to maintain adequate ride height at all times while driving.

Thirty day or 500 mile test — I understand that I must recheck the air spring system after 30 days or 500 miles, whichever comes first. If any part shows signs of rubbing or abrasion, the source should be identified and moved, if possible. If it is not possible to relocate the cause of the abrasion, the air spring may need to be remounted. If professionally installed, the installer should be consulted. Check all fasteners for tightness.

MAINTENANCE GUIDELINESBy following these steps, vehicle owners will obtain the longest life and best results from their air spring.

1. Check the air pressure before driving.

2. Never inflate beyond 125 PSI.

3. If you develop an air leak in the system, use a soapy water solution to check all air line connections, before deflating and removing the spring.

4. When increasing load, always adjust the air pressure to maintain normal ride height. Increase or decrease pressure from the system as necessary to attain normal ride height for optimal ride and handling. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle.

FOR YOUR SAFETY AND TO PREVENT DAMAGE TO YOUR VEHICLE, DO NOT EXCEED MAXIMUM GROSS VEHICLE WEIGHT RATING (GVWR), AS INDICATED BY THE VEHICLE MANUFACTURER. ALTHOUGH YOUR AIR SPRINGS ARE RATED AT A MAXIMUM INFLATION PRESSURE OF 125 PSI, THE AIR PRESSURE ACTUALLY NEEDED IS DEPENDENT ON YOUR LOAD.

5. Always add air to the springs in small quantities, checking the pressure frequently. Sleeves require less air volume than a tire and inflate quickly.

6. Should it become necessary to raise the vehicle by the frame, make sure the control system is turned off before lifting.

NOTE

CAUTION

troubleshooting Guide1. Leak test the air line connections, the threaded connection into the air spring, and all fittings

in the control system.

2. Inspect the air lines to be sure none are pinched. Tie straps may be too tight. Loosen or replace the strap and replace leaking components.

3. Inspect the air line for holes and cracks. Replace as needed.

4. Look for a kink or fold in the air line. Reroute as needed.

If the preceding steps do not solve the problem, it is possibly caused by a failed air spring — either a factory defect or an operating problem. Please call Air Lift at (800) 248-0892 for assistance.

Frequently asked QuestionsQ . Will installing air springs increase the weight ratings of a vehicle? No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR)

of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty.

Q . How long should air springs last? If the air springs are properly installed and maintained they can last indefinitely.

Q . Will raising the vehicle on a hoist for service work damage the air springs? No. The vehicle can be lifted on a hoist for short-term service work such as tire rotation

or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off of the air springs.

Pressure determination comes down to three things — level vehicle, ride comfort, and stability.

1 . Level vehicle If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side,

then it is not level. Raise the air pressure to correct either of these problems and level the vehicle.

2 . Ride comfort If the vehicle has a rough or harsh ride it may be due to either too much pressure or not

enough. Try different pressures to determine the best ride comfort. See Air Lift suggested driving air pressure.

3 . Stability Stability translates into safety and should be the priority, meaning the driver may need

to sacrifice a perfectly level and comfortable ride. Stability issues include roll control, bounce, dive during braking and sponginess. Tuning out these problems usually requires additional air pressure, strut damping, or both.

tuning the air Pressure

1. If there is a problem with a swivel fitting:

a. Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting and pulling firmly on the air line. Trim 1” off the end of the air line. Be sure the cut is clean and square (see fig. 8). Reinsert the air line into the push-to-connect fitting.

Fixing leaks

1. Inflate the air spring to 80 PSI.

2. Spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and 4/5 water. Spot leaks easily by looking for bubbles in the soapy water.

3. After the test, deflate the springs to the minimum pressure required to restore the system to normal ride height.

4. Check the air pressure again after 24 hours. A 2 - 4 PSI loss after initial installation is normal. Retest for leaks if the loss is more than 5 lbs.

Installing the Air Tank and Components

IMPORTANT: Depending on the orientation of the tank when it is mounted, the fittings may go into different ports on the tank. The drain valve must always be put into the port facing downwards (Figure 2).
