*3.5" aluminum - rear yoke included*

The factory driveshaft in the GTO is the weakest part of the entire driveline. It's a two piece design that is only 2 inches in diameter and uses rubber mounts instead of u-joints. Not only do the rubber mounts contribute to wheelhop, they are notorious for failing on even slightly modified 6 speed cars. Our heavy duty driveshafts are a one-piece design that use forged 1350 series u-joints. Each driveshaft comes with a cryogenically frozen front yoke and a custom machined 300M billet pinion yoke adaptor (shown below). NOTE: Due to the physical size of this driveshaft, the factory exhaust may require some modification. Most aftermarket exhausts tested do not have clearance issues. Steel driveshafts not recommended for 6 speed cars. Driveshaft needs additional spacer if using Harrop Differential cover.
