// THE FULL RUNDOWN

If you're diving into a re-gear project, let me tell you, Yukon Gear Kits have got your back. These kits come packed with everything you need to get your differential back in action—front and rear ring and pinion gear sets, plus the Yukon Master Overhaul Kits, all rolled into one part number. It’s like having a toolbox with all the right tools, but for your differential. Yukon’s ring and pinion gear sets are pretty much the gold standard in the gear world. The folks at Yukon really know their stuff; they use cutting-edge design techniques and advanced heat-treating processes to make sure every gear is tough and ready for action. You won’t find any flimsy parts here—the structure and surface finish meet some pretty strict standards, so you can trust these gears to hold up. Now, let’s talk specifics. These kits come with everything you need: gears, bearings, and all those little bits and bobs that are essential for a complete rebuild of your differential. You’ve got gear ratios ranging from 3.73 to 5.38, so whether you’re looking to up your towing game, tackle some serious off-road trails, or just replace those worn-out gears, you’ll find a ratio that fits your needs. One of the best parts? Yukon offers a lifetime protection plan called the Y.E.S. Plan. That means you’re covered for as long as you own your vehicle—no questions asked. It’s a nice peace of mind when you’re investing in quality gear.

// COVERED WHEN IT COUNTS

THIS PART //

Backed by the full Yukon Gear & Axle manufacturer warranty. JAP is an authorized dealer — your warranty is valid from day one.

FULL MANUFACTURER WARRANTY

Every part ships new in the box with the manufacturer's standard warranty — terms and duration vary by brand (typically 1 year to limited lifetime on hard parts). We only sell through authorized channels, so coverage is never voided by gray-market sourcing.

WE RUN THE CLAIM WITH YOU

Warranty issue? Don't fight the manufacturer's phone tree alone. Hit our team with your order number and photos — we open the claim with the brand and stay on it until it's resolved.

WHAT WARRANTY DOESN'T COVER

Defects in materials and workmanship are covered. Trail damage, improper installation, modification, and normal wear items (bushings, pads, wear plates) generally are not — that's standard across every brand we carry.

SEPARATE FROM RETURNS

Warranty claims (defects after use) and returns (unused parts within 30 days) are different lanes. Not sure which applies? Message us first — we'll route it the fast way.
