Axles and driveshafts are the first thing to break when adding more power and track time. Our 1pc driveshafts are lighter than stock and made from premium aluminum and carbon fiber materials. Axles shafts also can break with wheel hop and too much power. Upgrading to a heavy duty shafts can ensure all power get transferred to the tires. Upgraded driveshafts and axles are a must have when adding superchargers, turbo or any power adder.
