Motive Gear Performance

Motive Gear is the leading manufacturer of driveline products for just about any vehicle, whether it is a stock daily driver to full-competition 4×4 or racecar. We are proud to offer an unmatched selection of quality components engineered and manufactured for the vehicle and for the way it is driven. Motive Gear products are engineered to meet or exceed OEM specifications at a price that won’t break your budget. Our broad selection of ring & pinion ratios, limited slip and locking differentials, carriers, spools, manual transmission and transfer case components, rebuild kits, bearings, seals, gaskets, shims and hardware is available for just about every vehicle made from the 1940s through the present. DIY customers and professional installers alike appreciate our installation kits, which come complete with everything needed to install a ring & pinion set, right down to the seals, gaskets, and RTV.

Motive Gear Performance products are engineered to endure extreme punishment in dedicated racing vehicles operating in the harshest environments. We partner with several off-road, drag and dirt track racing teams to make our performance gearsets the toughest on the market. Motive Gear Performance gearsets are, in fact, tough enough to survive in a 10,000-horsepower Top Fuel dragster or climb over six-foot boulders in an Ultra-4 rock racer. Our competition-grade gearsets are cut from 9310 steel, and then heat-treated to a precise hardness through a computer-controlled process. Instead of offering a few of the more popular ratios, Motive Gear Performance gearsets are available as many as twelve different ratios for all popular axle housings. Different courses present different challenges, and Motive Gear Performance is ready with the widest selection of gear ratios to help racers be as competitive as possible wherever they run. Racers know Motive Gear Performance gearsets will see them through to the checkered flag race after race. Need help finding the right gearset for your needs? Check out our easy-to-use-gear ratio calculators.

All Motive Gear and Motive Gear Performance products meet strict quality standards through advanced manufacturing techniques and are backed by our strong warranty. Our in-house quality control lab utilizes state-of-the-art equipment to continuously check Motive Gear products for strength, tolerance, and hardness. Only after meeting stringent quality standards are Motive Gear products packaged, ready for fast delivery to our customers. With four strategically located regional warehouses, Motive Gear products can be shipped to most locations worldwide within 2-4 days.



From the flywheel to the drive wheels, minivan to Top Fuel Dragster, we’ve got it covered. Motive Gear offers individual components as well as complete rebuild kits for most popular manual transmissions, transfer cases, and axles featured in vehicles built from the 1940s through today. Because Motive Gear and Motive Gear Performance ring & pinion gearsets are offered in several ratios for each application, our customers enjoy unmatched customizing flexibility. Our complete line of catalogs help our customers find the driveline parts they need by vehicle application, ring gear size, differential, or transmission manufacturer. Motive Gear also offers a complete listing of replacement differential components for the Jeep Matrix. We can also produce custom components on a limited basis.

Gear Calculators

To help installers and drivers find the Motive Gear parts they need, we provide gear calculators for narrowing ratio choices to achieve the desired performance within a specific application.   These tools take a lot of guesswork out of gearset selection by offering the opportunity to see how different combinations of transmission gearing and axle ratios affect engine RPM under various circumstances. The Motive Gear drag performance calculator helps determine the best axle ratio for any drag vehicle to achieve the desired quarter or eighth-mile performance. Our street performance calculator helps determine the currently installed axle ratio in a vehicle based on engine RPM at a given speed. Using this tool allows customers to customize their current gearing to increase performance or economy. The manual transmission gear ratio calculator helps our customers tailor the spread between gears in 4, 5, or 6-speed manual transmissions to help keep engine RPM in the “sweet spot”, enhancing efficiency and performance.
