If you’re looking to really amp up your differential's performance, the USA Standard Gear Re-gear & Traction Kit is a solid choice. This isn’t just another upgrade; it’s a complete package that brings together a ring and pinion set, an installation kit, and the Yukon Dura Grip limited slip positraction unit. I’ve installed these kits on my own rig, and let me tell you, they make a noticeable difference.

The Yukon Dura Grip is where it really shines. It’s designed to give you that perfect balance of smooth and aggressive traction, which means you can tackle all kinds of terrains with confidence. Whether you’re hitting the trails or just cruising around town, you’ll appreciate how well it grips. Plus, it’s built to last; the high-strength nodular case and forged 4320 chromoly spider gears ensure you’re not just getting a temporary boost. And if you ever need to rebuild it, you can—this thing is completely rebuildable, which is a huge plus for anyone who likes to keep their gear in top shape.

The rigorous in-house quality testing that USA Standard Gear puts their products through is impressive. They make sure that every gear passes dimensional, material, and fitment tests, so you know you’re getting something reliable. With a variety of OEM and aftermarket ratios available, these ring and pinion sets are built to handle the grind of daily driving, spirited adventures, and everything in between.

This particular kit includes the 11.25" Dana 80 rear ring and pinion gear set with a 3.73 ratio, which is perfect for those looking to increase traction with a more aggressive gear ratio while adding that limited slip differential in one go. It’s designed to fit the rear position and comes with a master install kit, including a 4.375 in. O.D. inner pinion bearing race (NP673386/ NP516549). If you’re behind the wheel of a Ford F-350 from 1999 to 2016, this is the upgrade you didn’t know you needed.
