These rebuild kits are set up for PSC Saginaw steering gears with a 3.125" bore, giving you what you need to freshen up a worn box and get it back working the way it should.
Inside each kit, you’re getting the seals and internal components matched to your specific gear configuration—whether that’s Gen1 or Gen2, different input sizes, or billet vs OEM covers. No digging around trying to piece together the right parts.
Once it’s back together, the steering feels tight again, response is where it belongs, and you’re not chasing leaks or slop in the system.
