If you're diving into a re-gear project, you might want to check out the Yukon Gear Kits. These kits come packed with everything you need to get your differential sorted out—front and rear ring and pinion gear sets, plus a Yukon Master Overhaul Kit, all rolled into one part number. No more hunting around for individual pieces; it’s all here.
Now, let’s talk about the quality. Yukon Gear & Axle has built a reputation for high-performance gear sets, and it’s easy to see why. Their engineers are using some of the latest design techniques and heat-treating methods to make sure these gears hold up under pressure. They’ve got rigorous testing processes in place, so you can trust that the structure and surface finish of these gears meet some pretty high standards.
This specific kit includes a 3.55 Ring & Pinion Gear Set, perfect for applications with a 10 Bolt Rear Cover and 10 Bolt Ring Gear. The inner pinion bearing has an outside diameter of 3.250 inches, which is just one of the details that shows Yukon's commitment to quality. Plus, the ring gear diameter is 8.8 inches. It’s all about the little things that make a big difference.
What’s more, this Pro Kit is loaded with top-notch components. You’ll get premium Yukon ring and pinion sets along with a Yukon Master Install Kit that features high-quality Timken bearings and all the small parts you need to get your vehicle back on the road without a hitch. And let’s not forget the Dura Grip Clutch Style Limited Slip (LSD) included in the kit—fully rebuildable, too, so you can keep it running for the long haul.
Thinking of beefing up your tire size or need a little extra towing power? Maybe you’re just replacing some old, worn gears. These combo kits have got you covered. They save you both time and money by bundling everything you need into one easy package. Plus, with Yukon’s Y.E.S. Plan, you’re looking at a lifetime, no-questions-asked warranty for as long as you own your vehicle. That’s peace of mind right there.
