Speedway Motors 91025619 Details

O-ring rebuild kits for stock clutch hydraulic throwout bearing 910-25610 for GM 3-speed and 4-speed transmissions. For bearings built after 1-1-2007.

The 910-25610 bearings produced after 1-1-2007 are much smaller than racing versions so they will fit behind "thicker" stock style clutches. This new design is also much cleaner as it has no boss on the body. It also features a retainer to prevent over-extension and seal damage.
