Product Overview
Wavetrac® differentials are state-of-the-art helical gear units designed, developed, and manufactured in the USA by Autotech Driveline. The Acura RSX and Honda Civic Wavetrac® Differential is the only torque biasing differential on the market featuring patented technology that actively mitigates wheelspin during unloaded wheel conditions.
When axle load drops to zero, the Wavetrac® cam mechanism generates internal load, maintaining drive to the gripping wheel—unlike conventional torque biasing differentials that behave like open diffs in such scenarios.
Each unit is built with ultra-strong 9310 alloy steel gears, enclosed in case-hardened steel bodies and secured with ARP® fasteners. All Wavetrac® differentials include a transferable Limited Lifetime Warranty.
