Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Wavetrac BMW E82 E90 F30 F32 Limited Slip Differential – fits 135i, 328i, 330i, 335i, 428i and 435i

Transform the way your BMW puts power down with the Wavetrac Limited Slip Differential. This helical, torque-biasing LSD is engineered to maximise traction, sharpen corner exit speed and boost real-world acceleration on road and track. Wavetrac is the only torque-biasing differential with a patented internal cam device that maintains drive when one wheel is unloaded, dramatically reducing wheelspin in low-traction or zero axle load situations where other helical diffs act like an open differential. Built in the USA with 9310 alloy steel gears, case-hardened steel bodies and ARP fasteners, it delivers durable, maintenance-free performance with a transferable Limited Lifetime Warranty.

At Nforcd, we use and recommend Wavetrac LSDs for BMW platforms because they simply work. Customers report a huge improvement in grip, stability and confidence in all weather conditions. If you want a BMW diff upgrade that improves traction without compromising daily drivability, this Wavetrac LSD is a proven choice for fast road and track day builds.
