Product Description
If you're serious about performance, you’ve probably heard of Motive Gear. These guys are known for crafting some of the toughest drive train components out there. Whether you’re hitting the trails or tearing up the asphalt, their differential ring and pinion sets are designed to deliver. I’ve had my hands on these, and let me tell you, the quality is evident right out of the box. They’ve got a massive selection of gear ratios for pretty much any application you can think of, which is a huge plus when you’re dialing in your ride.
The Motive Gear Differential Ring and Pinion is a solid choice for anyone looking to upgrade their setup. With a 3.89 gear ratio, it strikes a nice balance between power and efficiency, making it great for both off-road adventures and daily driving. Plus, the 8620 steel construction means it’s built to last, even under heavy load. You’ll find these components in the winner’s circle at racing events around the globe, which speaks volumes about their performance pedigree.
