Centerforce ? Flywheels, Performance Steel, 30.10 lbs, 168 Tooth Gear, 6 Bolt Crank, Fits Chevrolet Crate Engines & Swaps 8 Cyl

Centerforce(R) SFI-certified steel flywheels are CNC-machined from billet steel for precise, no-hassle, bolt-in installation. See extened description for application-specific information.

This Centerforce billet steel flywheel solves a variety of problems associated with LS swaps utilizing earlier (non-LS) transmissions. Most LS engines have a crank offset that is 0.400" shallower than earlier generation Chevy small blocks. This presents a problem for those wanting to use a later LS engine with a manual transmission that was originally attached to a non-LS application, such as a Muncie 4-speed. This different crank offset causes internal bellhousing geometry problems with throwout bearing travel and clutch engagement when attempting to use an off-the-shelf LS flywheel with an earlier transmission. This flywheel bolts to a standard LS 6-bolt crankshaft but is machined with an extra 0.400" of thickness, compensating for the LS crank offset and placing the flywheel face and clutch assembly in the proper position to work with earlier transmissions. Centerforce(R) steel flywheels are manufactured from high quality billet steel and match closely to the original equipment flywheel weight. Billet steel flywheels are available for popular import and domestic vehicles, including trucks. Centerforce steel flywheels are CAD/CAM-designed and CNC-machined from billet steel for precise, no-hassle, bolt-in installation. Centerforce billet steel flywheels are SFI-certified, so you know that you can count on them, on the street and on the track.
