If you're serious about your ride, you’ve probably heard of Motive Gear. These guys are known for crafting some of the toughest drivetrain components out there. I’ve used their stuff, and let me tell you, they don’t mess around. Whether you're tearing up the trails or cruising on the highway, they’ve got a massive lineup of performance ring and pinion gear options that cater to just about any setup you can think of. Their products have made their way to the winner's circle at racing events across the globe, and it's no surprise why. The quality is top-notch, thanks to years of racing development and cutting-edge manufacturing techniques. Plus, their in-house engineers put everything through rigorous testing, so you know you’re getting reliable gear.

Now, let’s talk about the Motive Gear Differential Complete Ring and Pinion Kit. This kit is a game-changer, especially if you’re running a Ford 9.75" rear end. With a ring gear diameter of 9.75 inches and a solid 4.89 gear ratio, you’ll get that perfect blend of power and efficiency. The kit includes 39 teeth on the ring gear and 8 on the pinion, making for a smooth ride whether you’re on the road or off it.
