ATB LSD Differential for BMW 3.15 Final Drive

The Wavetrac ATB LSD Built Differential represents a technologically advanced solution for BMW owners seeking improved traction and driving dynamics. This unit is specifically engineered for select BMW 1' F20, 118dX, 120d, and 120dX models equipped with a 3.15 final drive axle, utilizing the part number 33107603748-W-1. Installation of aftermarket differentials on BMW models from 2007 onwards can be complicated by the factory's use of friction-welded ring gears and differentials. This often requires precise machining to separate these components and install a new differential, leading to potential vehicle downtime. Wavetrac has developed a solution for specific BMW axles, including the 33107603748 3.15, to streamline this process. Regal Autosport offers various services, including machining and installation, to facilitate the integration of the Wavetrac LSD into customer-supplied axles or new BMW axles. It is crucial to note that axle specifications can vary by model, trim, and market. Therefore, supplying your vehicle's VIN is recommended for Regal Autosport's team to cross-check the correct factory-specified axle for your BMW, ensuring compatibility. The product is supplied dry and requires filling to the manufacturer's specified level with oil before use. The Wavetrac differential is built to high standards, with internal gears crafted from high-strength 9310 alloy steel.
