Wavetrac differential lock

For rear-wheel-drive vehicles, a limited-slip differential is, according to many of our customers, the best and first modification you should make, even though it is a significant investment. The impact on drivability, traction, and overall performance is substantial, making the car significantly more predictable and easier to control.

Installing an LSD benefits both all-wheel-drive and rear-wheel-drive models, though it is most essential for the latter. With an open differential or a lightly locking stock unit, the car tends to spin its wheels unpredictably, causing inconsistent handling.

Torsen-type differentials operate silently and integrate well with factory traction control systems. They are maintenance-free, come with a lifetime warranty, and perform their job seamlessly. Wavetrac represents the latest technology in this category and is uniquely designed to handle zero-traction situations. Always reliable locking!
