American Powertrain's Science Friction flywheels are available for most GM, Ford, Mopar, and AMC V8 engines. Their high-performance billet steel or lightened billet steel flywheels work best on the street for smooth performance—and for drag racing where the flywheel stores energy for hard launches. Billet aluminum flywheels are preferred for high-revving engines and in road racing where rapid rpm gain is essential. More than 50 models and configurations are available; order the flywheel recommended for your engine application.

Features include:

* High-grade billet steel or aluminum
* Heavy-duty ring gears (with welded tabs on aluminum flywheels)
* SFI certification is available on every flywheel
* 20 percent lightening is available on steel flywheels
* Double Blanchard-ground steel friction plates on aluminum flywheels
* Aluminum flywheels have aircraft-grade riveted friction plates
