If you are building an all-out competition car, then you need a lightweight flywheel that will allow the engine to rev quicker, while not consuming horsepower. G Force billet aluminum flywheels greatly reduce rotating weight to permit quicker engine revving, as opposed to the slower revving heavier steel flywheels. These distinct features translate directly to how your vehicle will perform. Vehicle weight, engine HP, torque, and gearing combinations all factor into the final performance, but as a general rule, an aluminum flywheel requires more HP than a steel flywheel to make the car launch without bogging the motor, while an aluminum flywheel accelerates quicker through the gears, compared to the heavier steel flywheel.

NOTE: G Force Part #153105AHRI requires a rigid clutch disc, and is an excellent flywheel for circle track racing.

153 – 105 – AH – R – I

153 = Teeth on the outside starter ring gear / 153 Tooth GM Ring-Gear on this GM 153T flywheel.

105 = Stands for the clutch size this flywheel can use, in this case, it uses a 10.5” clutch disc kit.

AH = Aluminum material, flywheel CNC machined from high quality Billet Aluminum and not Cast iron.

R = Rigid Hub Race disc without springs can be used with this flywheel for circle track racing.

I = Internally Balance, meaning the flywheel does not balance crankshaft and is Neutral Balanced.
