The Driveshaft Shop (DSS) offers high performance 1pc driveshafts and heavy duty axle shafts for many late model performance applications. The 1-piece design offers improvements over the 2 piece stock driveshaft with less rotational mass and extra ground clearance for lowered vehicles. Carbon fiber driveshafts offer the highest strength to weight ratio for lowered ET's at the track. DSS direct fit IRS axles are rated up to 1400hp for extra strength when added a supercharger and drag racing applications. Rolled splines with billet CV mounts make these axle shafts extra strong. Great for street or race use. Each driveshaft we produce is dynamically balanced at over 9000 RPMs to ensure unbeatable reliability.
