Powertrax: Maximum Traction, Every Road Surface

Powertrax is one of the most recognized names in differential traction technology, built on a singular mission: deliver maximum traction to light trucks, sport utility vehicles, off-road rigs, and performance street rods. As a leading manufacturer of traction-adding differentials, Powertrax focuses on three core principles — traction, street-ability, and easy installation — across every product in their lineup.

The brand's heritage traces back to the original Lock-Right locker, a pioneering drop-in design that could be installed in an existing differential case without special tools or setup equipment. That philosophy of accessible, no-compromise performance still defines Powertrax today. Their differential lock assemblies cover the full spectrum of traction needs, from the aggressive, fully automatic Lock-Right — trusted by hardcore off-roaders and even United Nations vehicles in rugged terrain — to the street-refined No-Slip Traction System, which uses the patented SynTRAC™ synchronization mechanism to eliminate the ratcheting sounds typical of conventional lockers.

For drivers who want the best of both worlds, the Powertrax Grip series rounds out the portfolio. The Grip Pro is a gear-driven limited-slip differential housed in a fully machined, forged steel case, delivering progressive and variable traction based on throttle input. The Grip LS uses carbon-fiber and steel friction plate technology for smooth, consistent torque transfer — a favorite for daily-driven street machines. And for maximum competition-grade locking performance, the Grip Lok combines the automatic locking action of a traditional locker with the structural integrity of a fully machined case.

Beyond complete locking units, Powertrax offers differential carriers — fully assembled, ready-to-install case units like the Grip Pro and Grip Lok, engineered to drop directly into popular axle applications ranging from GM 8.5-inch to Toyota 10.5-inch differentials. For owners maintaining or restoring existing Powertrax-equipped axles, differential rebuild kits supply the genuine replacement components — springs, pins, couplers, drivers, and friction modifiers — needed to return a unit to factory specification.

Powertrax products are designed and manufactured in the USA and are backed by a two-year/100,000-mile warranty on all assembled units, including the Grip Lok, Grip LS, Grip Pro, Lock-Right, and No-Slip systems. Whether you're crawling boulders, pulling out of a snowy ditch, or chasing elapsed times at the drag strip, Powertrax has engineered a traction solution to match your demands.
