If you're in the market for some seriously tough drivetrain components, you can't go wrong with Motive Gear. These guys have been around the block and know what it takes to get the job done, whether you're hitting the trails or tearing up the asphalt. Their performance ring and pinion gear options are some of the broadest you'll find, with a range of ratios to suit just about any application you can think of. I've seen their products in the winner’s circle at racing events worldwide, and there's a reason for that. It's all about quality—years of racing development, solid design, and cutting-edge manufacturing techniques have gone into these components. Plus, their in-house engineers put everything through rigorous testing, so you know you're getting something that can handle the heat.

Let’s talk specifics: the Motive Gear Differential Ring and Pinion is designed for GM 7.5"/7.625" (10 Bolt) setups with a 3.23 gear ratio. What does that mean for you? Well, it’s perfect for those who want to maintain a balance between power and efficiency. The ring gear has a diameter of 7.5 inches and is made from 8620 steel, which is tough enough to take on whatever you throw at it. With 42 teeth on the ring gear and 13 on the pinion, you’re looking at a solid setup that can handle some serious torque. And if you're wondering about installation, it requires a 3.23 and numerically higher ratio carrier—so keep that in mind.
