SCAT Enterprises, Inc. has been manufacturing and distributing crankshafts, connecting rods and engine components for the automotive aftermarket since 1962. SCAT’s newest division, U.S. Crankshaft was established in 2009 to answer the unprecedented growth of SCAT’s custom line of billet and forged crankshafts. U.S. Crankshaft by SCAT has been making crankshafts from raw billets and forgings for over 45 years.
SCAT also offers a complete line of connecting rods in H-Beam & I-Beam designs and over 1,200 rotating assembly and block combinations for Chevy, Ford, Chrysler, Pontiac and Honda applications. Complete balancing is available for any SCAT crankshaft, rotating and block assembly . . .
U.S. Crankshaft has 2 complete crankshaft manufacturing lines to serve you. At the heart of these lines are
specialized crankshaft manufacturing equipment unlike equipment found in our competitor facilities, the centerpieces of which are 2 American GFM crankshaft milling machines. These machines weight 60,000 pounds, sit on 6 feet of concrete and have 100hp on demand. The cutting technology of these machines allows U.S. Crankshaft to machine your custom crankshaft stress free and to exacting stroke and index tolerances.

LIVE FROM REDONDO BEACH, CALIFORNIA, USA ... THE POWER OF U.S. CRANKSHAFT MANUFACTURING
Ability to make a raw billet into a crankshaft for most any application.
Overview of U.S. Crankshafts CNC machining line which includes 2 American GFM CNC machiningcenters.
U.S. Crankshaft utilizes 12 grinding machines employing a staff with a collective 200 years of grinding experience.
All U.S. Crankshafts are inspected 100% to ensure ultimate quality control.
All U.S. Crankshafts are heat treated to the most stringent tolerances and specs including ION nitriding (shown above) for surface hardness and ultimate strength.
Complete balancing is available . . . 4 new Hines balancers on-line to serve you.
SCAT Crankshafts, the sister line to U.S. Crankshaft has a complete line of connecting rods that are finish machined, honed and balanced in Redondo Beach, California.

DESIGN 1 PRO STOCK STANDARD WEIGHT CRANKSHAFTS
ALL STANDARD FEATURES IN ALL U.S. CUSTOM CRANKSHAFT BILLETS
• Straight shot & chamfered oil holes • ION Nitride hardened for superior wear resistance• Lightening holes in all rod throws • Large radius on all journals • Precision ground, heat treated & shot peened
DESIGN 2 PRO COMP LIGHTWEIGHT BILLET CRANKSHAFTS
Perfect for engines wanting quicker RPM’s, SCAT’s Pro Comp cranks use a computer generated symmetrical counterweight system to reduce rotating mass. This reduces stress on the block, crank flex, and overall weight while increasing horsepower and acceleration. Scat’s aero wing counterweight edge design reduces horsepower robbing windage and oil turbulence in the crank case. Ideal for competition engines using medium weight components while demanding maximum performance.
DESIGN 3 SUPERLIGHT BILLET CRANKSHAFTS
SCAT’s Super-Lite cranks carry the Pro Comp style crankshaft to the next level. The computer generated Pro Comp symmetrical counterweight system now incorporates the pendulum cut on the inner face of the counterweights. This metal removal does not sacrifice strength. It removes unnecessary material, thereby further reducing rotating mass. Ideal for competition engines using lightweight components, running higher RPMs while demanding lightening acceleration.
DESIGN 4 FEATHER-LITE BILLET CRANKSHAFTS
A Feather-Lite crank is the next step in weight reduction. All the features of the Super-Lite with gun drilling added to the main line removing up to 5 pounds. This hole also equalizes the pressure between each cylinder for increased ring control for increased horsepower.
DESIGN 4 Q-LITEBILLET CRANKSHAFTS
This is the ultimate lightweight crankshaft, taking the Feather-Lite crank to the next level. An additional pendulum cut is taken on the outer face of the counterweights. Used in competition engines normally of shorter stroke. Nothing is spared to use the lightest components available, where high RPM and blinding acceleration is demanded without compromise.
