This housing is fully SFI approved. No transmission blankets or shields are required for competition. A special IKO roller bearing is installed in the rear of the case to reduce output shaft drag. This heavy duty casting requires no liners.
BTE uses this housing on all of its Top Sportsman, Pro Mod, and Top Dragster racing powerglide transmissions.
