If you’re diving into a re-gear project, you’re probably looking for something that won’t let you down. That’s where the Yukon Gear Kits come in. These kits are designed to pack everything you need for a solid differential rebuild into one neat package. You’ll get front and rear ring and pinion gear sets along with the Yukon Master Overhaul Kits, all under a single part number. It’s like having a toolbox that’s already organized for you.
Now, let’s talk about the gears themselves. Yukon’s ring and pinion gear sets are known in the automotive world for their quality. The engineers over at Yukon really know their stuff—they utilize advanced heat-treating techniques and rigorous quality testing to make sure these gears are tough enough to handle whatever you throw at them. You can expect a solid structure and a smooth surface finish that meets high standards.
These kits come with everything you need to get your differential back in action, including gears, bearings, and all those little parts that seem to disappear when you need them most. You can choose from a range of gear ratios from 3.73 to 5.38, so whether you’re looking to up your tire size, boost your towing capacity, or just replace some worn-out gears, Yukon has got you covered.
And let’s not forget about the Y.E.S. Plan. This lifetime protection plan covers your gear set kit for as long as you own your vehicle. It’s a no-questions-asked warranty that gives you peace of mind.
