The cover assembly is machined from billet aluminum and is then Type 3 hard anodized. Our billet covers have roughly 25% more tensile strength than the competition’s cast unit. By focusing our ability on machining the strongest cover possible while maintaining minimal weight, we are basically able to eliminate any flex in the cover. Our billet covers see only .003" of flex where as a cast or stamped unit can see as much as .030" of flex. By eliminating this flex in the cover, the driver is able to operate the clutch much more consistently and confidently. All the movement being applied to the diaphragm of the clutch from the throwout bearing is used solely to engage and disengage the clutch and isn't wasted by the cover flexing first. The strength of our covers also results in greater clamping force over the same amount of area vs. a cast or stamped cover. This means our triple discs are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized.

Utilizing our Wave Drive hub system that incorporates one 26T splined hub and then the two other discs that register on the wave drive hub. A single splined hub allows for easier installation and alignment as well as a stronger hub overall. 

Our 550 Series kits are sold complete with steel button flywheel, triple disc clutch pack, and hardened steel flywheel.
