Centerforce manufactures the best in SFI approved performance flywheels by using high-strength billets, not castings. Centerforce ''800'' and ''900'' flywheel part number prefixes designate specially made flywheels from aircraft grade billet aluminum for light weight (low inertia). Centerforce aluminum flywheels also feature mechanically retained starter ring gears as well as replaceable steel friction surfaces that have been heat-treated for abrasion resistance and long life.

All Centerforce flywheels are CAD/CAM designed and then CNC machined to strict tolerances for perfect fitment and hassle-free, bolt-in performance.
