Wavetrac® combines helical-gear engineering with a patented cam mechanism to offer the only torque-biasing differential that generates internal preload under zero axle-load conditions. Designed, developed and manufactured in the USA to ISO 9002 and TS 16949 standards, Wavetrac units provide slip-free power delivery even when one wheel loses traction.

By automatically “loading” the unloaded wheel, the Wavetrac device maintains grip and drive confidence during hard cornering or wheel-lift scenarios. Available for a broad range of passenger and performance cars—from Corvettes and BMWs to Volkswagen and Ford applications—each differential is bench-tested for durability and tuned for seamless on-road behavior
