Billet Aluminum and Steel Flywheels for GM
Billet Aluminum Flywheel Billet Steel Flywheel
Every Billet Aluminum Flywheel we sell can
be SFI Certified for racing with just a click.
Every Billet Steel Flywheel we sell
can be lightened with just a click.
   


 
 
When it comes to Billet
Aluminum Flywheels
American Powertrain
has the market beat hands down.

 
These flywheels are made of a single billet of high grade aluminum and feature a durable steel insert that is cross ground and riveted with aircraft grade T6 fasteners. 

They are also the least expensive Aluminum option on the market, guaranteed.   
 
Our 168 tooth 11” flywheels are drilled for the 10.5” and 11” clutch bolt patterns and are race balanced to match your engine.

 

     Why pay more for Billet Steel
  Flywheels? All of American Powertrain's steel flywheels are
SFI quality and can be
SFI Certified for racing
with one click if needed.
Otherwise, you get all the safety of a race grade flywheel for less.  Most of our 11” flywheels are drilled for the 10.5” and 11” clutch bolt patterns and are race balanced to match your engine.
 
We also offer the option to lighten these flywheels, reducing weight by about 20% without degrading the strength and durability of the flywheel.  This is a great alternative to more expensive aluminum flywheels if you need a lighter option. 
 
We also offer big savings on 1986-newer engine flywheels, which usually carry a premium.
You get ours for the same low price as pre-‘86 flywheels every day.
