If you're serious about your Jeep, you know how crucial it is to have the right gear setup. That's where Motive Gear comes in. These guys have been in the game long enough to know what it takes to make tough drive train components. Their differential complete ring and pinion kit is designed specifically for the Jeep JK Rubicon, and trust me, it’s built to handle whatever you throw at it—whether you’re hitting the trails or just cruising around town. This kit features an 8.5-inch ring gear, which is pretty standard for the Dana 44 setup in the JK Rubicon. You’re looking at a gear ratio of 5.13, which is perfect for getting that extra torque when you need it, especially if you’ve got larger tires. Speaking of tires, this setup clears up to 35s without any major modifications, so you can beef up your rig without worrying about fitment issues. Now, let’s talk about the materials. The ring gear is made from 8620 steel, which is tough as nails and designed to withstand the rigors of off-roading. The pinion shaft has a diameter of 1.376 inches and comes with 24 splines, ensuring a solid connection. Plus, with 41 teeth on the ring gear, you’re getting a smooth ride and reliable performance. Everything you need is included in the kit, from the ring and pinion gears to the necessary bolts—10 for the ring gear and another 10 for the cover. What really sets Motive Gear apart is the testing they put their products through. Their in-house engineers rigorously test everything to ensure it meets the demands of real-world use. So, you’re not just getting a part that looks good on paper; you’re getting something that’s been proven in the field. Key Features: Notes: This kit is specifically for the Dana 44 differential on the JK Rubicon. It’s designed to fit seamlessly and includes Timken bearing kits for added reliability.
