Wisefab Rear Halfshafts Kit, BMW E90 / E92

Wisefab strives to engineer the best products that allow drivers to push their limits on the track. Behind its unique designs are countless hours of research, problem-solving, and meticulous development. Wisefab Dynamic Halfshaft Axles can hold 1500hp and offer outstanding reliability. The axle shaft strength is designed to be just a little below the strength of differential output shafts. Wisefab axles use CV joints with low wear and high strength. As expensive drivetrain components become commonplace in most rally, drift, and race cars, it is important to create a system between them that enhances their longevity. The key is superior shaft material that not only has high-yield strength but can also survive deformations or twists. Wisefab shafts will flex to absorb the excess of critical torque. In these situations, the shafts can twist to at least 90 degrees, often reaching 180 degrees or even 360 degrees without failure, allowing the driver to finish the race in one piece. It is important to note that any twisting won’t occur until the torque limit has been reached. If the shafts do twist more than 90 degrees, it is recommended to replace them. NOTE: Every set of halfshafts is built to order according to customers specification.
