Dana is one of the world's leading axle manufacturers, providing single-source, customized axle innovation - from design to assembly. Each axle, drive pinion and ring gear assembly we produce is custom designed to meet or exceed each customer's requirements. For example, the Hydra-Lok™ limited slip differential improves vehicle power flow while offering drivers greater control under a variety of challenging road conditions. Our unique transaxle auxiliary drive unit redirects torque from an existing front-wheel-drive system to the rear, enabling customers to adapt a passenger vehicle powertrain design to a four-wheel-drive system. And we offer a wide variety of wheelend designs for independent front and rear suspension systems, as well as conventional rigid axle designs to meet customer needs.
Dana Spicer Ring and Pinions are the same gears that came in your Dana axle from the factory. Available in most popular performance and replacement ratios. Process-controlled machining, heat treatment, face hobbing, shot peening, and lapping operations provide a smoother, quieter ride and years of trouble-free service.
