If you're looking to re-gear your axle without all the hassle, the USA Standard Gear Ring Gear & Installation Kit is worth checking out. This kit is pretty straightforward—just one part number gets you a complete ring and pinion set along with everything you need for installation. I’ve used these guys for a while now, and I can tell you that they don’t cut corners. Each gear goes through some serious quality testing to make sure it meets all the standards for dimensions, materials, and fitment. Whether you’re commuting, hitting the trails, or just enjoying a spirited drive, these gears are built to handle it all.

This specific kit features the USA Standard 8.5" GM rear ring and pinion gear set with a 3.42 ratio. It also comes with a master install kit that includes axle bearings and seals. You’ll be all set with a 1.781" carrier bearing journal, so you can swap it in without any fuss.
