If you're looking to re-gear your axle without a headache, the USA Standard Gear Ring Gear & Installation Kit is a solid choice. It’s pretty straightforward—one part number gets you a complete package that includes both a ring and pinion set along with an installation kit. I’ve used these kits on my own builds, and I can tell you, they’re built to last. USA Standard Gear really puts their stuff through the wringer with quality testing to make sure everything meets the mark—dimensional checks, material integrity, and fitment tests are all part of the deal. Whether you’re navigating city streets, hitting the trails, or just enjoying some spirited driving, these gears are built to handle it all.
Now, if you’re working with a GM setup, the USA Standard 8.5" Rear Ring & Pinion Gear Set with a 4.56 ratio is a great option. This package comes with a master install kit, including axle bearings and seals, and it’s designed to fit a 1.625" carrier bearing journal. It’s perfect for those who want to get a little more torque out of their ride.
This is an 8.5 in. GM gear and install kit package that includes a 4.56 ratio gear set and a master install kit. It fits a 1.625 in. carrier journal and comes with 2.8 in. OD axle bearings and seals.
