Sonnax Automatic Transmission Clutch Steels
Upgrade your transmission's clutch pack with Sonnax automatic transmission clutch steels. These premium-quality steel parts give you the best combination of coefficient of friction and performance. Sonnax offers severe-duty clutch steels for use in a variety of automatic transmissions—including racing applications. These steels are available with up to double the number of external teeth as OE. With more teeth engaged, wear should be reduced dramatically. Anti-drag tabs create the maximum clearance between the friction and steel when the clutch is disengaged. Turbulator holes reduce parasitic drag. Combining anti-drag tabs and turbulator holes significantly reduces the heat generated when the clutch freewheels.

RAM Billet Steel Flywheels
Cast flywheels are not explosion-proof and can be dangerous when used in high performance applications at higher rpm. RAM billet steel flywheels are recommended as replacements for factory-cast flywheels in high performance and racing vehicles. Made in America and produced in-house, all RAM flywheels are computer balanced within a 1/2 oz., surface ground (which results an optimum mating surface), and are ready to run out of the box. They're better for launching heavier drag race cars and provide better drivability in street vehicles. SFI-approved, RAM billet steel flywheels are CNC-machined from certified materials. Order the model recommended for your year/make and engine application. Technical note: As they spin, heavy flywheels store more energy than lighter ones. Engine and gearing combinations that require more power or inertia to make the car launch without bogging the motor need heavier flywheels. However, heavier flywheels accelerate slower. Lighter flywheels create less inertia at launch, but accelerate quicker through the gears. When choosing a flywheel, you must consider the car's weight, operating rpm of the engine, and, most importantly, the gearing. Insufficient gearing will cause an engine with too light of a flywheel to "bog" on launch.
