This is the replacement bearing for our FF1600 Hydraulic Release Bearing Kit, Part No. 163-55.
A worn-out bearing can tighten up or even seize, spinning the piston and causing seal failure. In extreme cases, the piston can be damaged and the entire assembly must be replaced. A new bearing is cheap insurance!
This bearing snaps onto the snout of the piston. The 38mm - 52mm flat contact surface can be used with many different clutches, including Tilton, AP, and QuarterMaster 5.5" and 7 1/4" racing clutches.
