Motive Gear Differential Ring and Pinion Complete Kit for Jeep 1997-2006 MGK-114
$746.98

If you’re looking to beef up your Jeep's drivetrain, you’ve got to check out the Motive Gear Differential Complete Ring and Pinion Kit. This isn’t just any kit; it’s designed specifically for the Jeep TJ, covering both front and rear, and it’s built to handle whatever you throw at it—whether that’s mudding, rock crawling, or just cruising around town.

Now, let’s talk specs. This kit features an 8.5-inch ring gear made from tough 8620 steel, which means it’s ready to take a beating. You’re looking at a 4.88 gear ratio, perfect for getting that low-end torque you need for off-road adventures. The pinion shaft has a solid 1.376-inch diameter and a 26-spline count, so you know it’s built to last. Plus, with 9 teeth on the ring gear and 44 on the pinion, you’re set for some serious power transfer.

One of the best parts? It fits right into your Dana 30 front and Dana 44 rear without any fuss. Just keep in mind, if you’re currently rocking a 3.73 ratio, you’ll need a new rear carrier to make this work. And if you’re on a 3.54 or 3.07 ratio, you’ll need to swap out both front and rear carriers. But trust me, the upgrade is worth it.
