Detroit Truetrac Differentials

Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket. It remains the leading helical gear-type limited-slip differential in the industry. Its proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction. Recognized not only for its durability but also it's smooth and quiet operation.

Power transfer is so smooth; it literally goes unnoticed by the driver. Engineered to work efficiently in front and rear axles. No maintenance - Just Traction!
