If you're diving into a re-gear project, you know how crucial it is to get the right parts all in one go. That's where Yukon Gear Kits come into play. These kits are like a one-stop shop for everything you need to get your differential back in shape. You get front and rear ring and pinion gear sets, plus the Yukon Master Overhaul Kits, all bundled together under one part number. It’s really convenient for those of us who don’t want to hunt down every little piece separately.
Now, let’s talk about the heart of these kits: the high-performance ring and pinion gear sets. Yukon has built a reputation for quality in the automotive gear scene. They use some serious engineering smarts—think advanced heat-treating techniques and rigorous quality testing—to make sure these gears are tough as nails and ready to handle whatever you throw at them. You can trust that the structure and surface finish are up to snuff, meeting all the exacting specs you’d expect from a top-tier product.
Each kit comes loaded with everything you need to fully rebuild your differential. We’re talking gears, bearings, and all those little bits that can be a pain to track down. Plus, they offer a range of gear ratios from 3.73 all the way up to 5.38, so whether you’re looking to upsize your tires, boost your towing capacity, or just replace those worn-out gears, Yukon has you covered.
And here’s a sweet bonus: Yukon’s got this Y.E.S. Plan that offers lifetime protection for your gear set kit. It’s a no-questions-asked warranty that lasts as long as you own your vehicle. That kind of peace of mind is hard to beat.
Features:
- Compatible with applications featuring a 10 Bolt Rear Cover and 10 Bolt Ring Gear.
- The Inner Pinion Bearing has a 3.250" Outside Diameter, so you know it’s built for durability.
- Yukon Pro Kits come with top-notch components and boast one of the best warranties in the biz.
- The Pro Kits include premium Yukon ring and pinion sets, along with Master Install kits that feature high-quality Timken bearings and all the necessary small parts to get your vehicle back on the road in no time.
- Each Gear and Install Kit includes axle bearings and seals to make your rebuild smooth.
- You'll also find a Yukon Dura Grip Clutch Style Limited Slip (LSD) in the kit—it’s fully rebuildable, which is a nice touch for long-term use.
- The Ring Gear Diameter is a solid 8.8", ensuring strength where it counts.
- Yukon Pro Kits offer a comprehensive selection of differential repair and performance parts, all neatly packaged to save you time and money, with everything you need under one part number.
- This specific kit features a 4.11 Ring & Pinion Gear Set, perfect for those looking to fine-tune their ride.
