Wavetrac gear type limited slip differentials (LSD's) are a 'fit and forget' solution to improving your cars traction by reducing wheelspin. This makes them highly beneficial in tuned vehicles which struggle to put the power down to the road. Wavetrac are unique in that they are the only gear type differential to not lose drive in wheel lift situations making them ideal for track use.Fit and forget with no servicing or special oils requiredDirect replacement for OEM open type differentialsVastly improves traction during acceleration and hard corneringTransmits power to the wheel with most grip even in wheel lift situationsSuitable for road or track useBuilt using high strength 9310 steel gears and ARP fasteners for maximum reliabilityWhy do you need a limited slip differential. Standard (open) differentials are not really designed with performance in mind. We have all experienced wheelspin when accelerating particularly in wet conditions. This is because the standard differential trans
