The Wavetrac ATB Limited Slip Differential is a high-performance drivetrain upgrade designed to deliver maximum traction, stability, and durability under demanding driving conditions. Developed and manufactured in the USA, this premium differential uses advanced helical gear technology combined with Wavetrac’s patented torque-biasing system to maintain drive even in low-load or wheel-lift situations.
For LSD installation and rebuild options, a complete stock differential casing (“pumpkin”) is required. The unit will be rebuilt and returned fully assembled.
If you are unable to send your differential upfront, a refundable deposit option is available. The deposit will be refunded once a complete, usable and undamaged differential housing is returned within 28 days of receiving your rebuilt LSD unit. Units requiring repair or not in working condition may not qualify for refund.
Please provide your VIN and transmission type prior to purchase to confirm correct fitment.

⚠️ Fitment may vary depending on differential type and transmission configuration. VIN verification is required prior to installation.
Unlike conventional torque biasing differentials, Wavetrac’s patented design actively maintains drive under zero-load conditions, preventing the common loss of traction seen in standard ATB systems. This results in more consistent performance, improved cornering stability, and superior real-world drivability whether on road or track.
