Product Description

If you’re looking to really amp up your ride’s performance, the USA Standard Gear Re-gear & Traction Kit is where it’s at. This isn’t just a random upgrade; it’s a complete package that combines a ring and pinion set, an installation kit, and the Yukon Dura Grip limited slip positraction unit. I’ve installed one of these kits on my truck, and let me tell you, it transforms how you tackle different terrains.

The Dura Grip is a game-changer. It offers that perfect balance of smoothness and aggression, giving you the confidence to tackle everything from muddy trails to rocky paths. Plus, it’s built to last. With a high-strength nodular case, forged 4320 chromoly spider gears, and composite clutches, you know it’s tough enough for whatever you throw at it. And if you ever need to freshen it up, it’s completely rebuildable, which is a nice bonus for those of us who like to keep our gear in top shape.

What’s great about the USA Standard Gear kits is that they undergo rigorous in-house quality testing. They really put these gears through their paces to ensure they meet all the necessary dimensional, material, and fitment standards. So, whether you’re commuting, hitting the trails, or just enjoying some spirited driving, these ring and pinion sets are ready to handle it all. Upgrading to a more aggressive gear ratio while adding a limited-slip differential? Now that’s what I call a win.

This specific kit features an 11.5" AAM rear ring and pinion gear set with a 3.73 ratio, and it comes with a master install kit that includes a 4.375" OD inner pinion bearing. It's compatible with a range of GM and Chrysler/Dodge/Ram models, so you can be sure it’ll fit your ride without a hitch.
