If you're serious about your ride, you’ve probably heard of Motive Gear. They’re known for crafting some of the toughest drive train components out there, and for good reason. I’ve put their gear sets through the wringer, both on the trails and the track, and I can tell you, they don’t mess around. With a wide variety of performance ring and pinion gear options, Motive Gear has something for just about every application you can think of. Whether you’re hitting the dirt or cruising the streets, this stuff is built to last.
The Motive Gear Differential Ring and Pinion set is a solid choice if you're looking to upgrade. I’ve used the 4.88 ratio on my Jeep, and it made a noticeable difference in performance. The quality of these components comes from years of racing development and top-notch design, so you know you're getting something that’s been tested in the field. Plus, their in-house engineers really put these products through their paces before they hit the market.
