Billet Flywheels:
RAM billet steel flywheels are recommended as a replacement for
factory cast flywheels in high performance and racing vehicles.
Cast flywheels are not explosion proof and can be dangerous when
used in high performance applications at higher RPMs. RAM billet
steel flywheels are CNC machined from certified materials and exceed
SFI specifications. After machining, the flywheels are blanchard
ground parallel to the crankshaft mounting surface ensuring minimum
runout and the optimum mating surface for the clutch disc. Use steel
flywheels in heavier drag race cars or for the best driveability
in street driven vehicles.
The choice for most all out competition
vehicles, RAM billet aluminum flywheels are CNC machined from certified
materials and exceed SFI standards. A key feature of a RAM aluminum
flywheel is the ¼ inch steel friction insert. A well tuned
competition clutch system has a predetermined amount of slippage
at launch and on the gear changes. The flywheel insert must have
enough mass to absorb the heat generated by slippage without distortion;
ensuring maximum clutch life and consistent performance. Thinner
inserts can warp and lift causing uneven engagement across the clutch
disc. The thicker insert remains flatter and dissipates the heat
better. Each flywheel is precision ground after the steel insert
is installed to ensure the friction surface is parallel with the
crankshaft flange for minimum runout and to provide the optimum
mating surface for your choice of clutch disc.
