S&S, gear drive camshaft installation support kitProvides all parts needed to install the S&S Gear Driven Twin Cam camshafts. Comes complete with a replacement gear cover gasket; inner and outer cam ball bearings and retaining ring. S&S recommends to use the ball bearing design over the OEM roller bearing design. OEM bearings have more internal clearance which can cause more gear noise. The improved ball bearings are included in this S&S kit; as is the S&S Heavy Duty cam bearing retainer plate.
