New 911 Response Clutch Cover by Thunder Products
The TPI 911 Response Clutch Cover turns your ordinary OEM clutch into a high performance, long life, premium clutch assembly.
Billet machined aircraft grade aluminum, the TPI 911 Response clutch cover adds rigidity to the clutch towers eliminating the normal flexing. The rigid clutch assembly along with the huge oversize cover bushing (250% larger) will keep the sheaves in perfect alignment. This will eliminate binding and produce fast, smooth and accurate up-shifting and back-shifting. Clutch and belt life is increased!
