Superwinch called it a service kit. I have yet to find out exactly what is in it. I would guess that it would include the spring, gasket, o-ring, and snap ring. Maybe the small hex screws. I guess I need to e-mail them and find out. I also considered buying a spare set to keep in the truck. but with space at a premium and other stuff has priority, I haven't got them yet. <img src="/forums/images/graemlins/notooth.gif" alt="" />
