This single shaft is the same design that The Driveshaft Shop has been using in most modern muscle cars for the last 2 years and is a proven and trouble-free shaft for the Challenger. This shaft will replace the stock 2-piece shaft, and eliminate the disconnected feeling you get from the stock shaft with its Giubo (rubber drive) and soft hanger bearing rubber. The stock shaft has to have the Giubos twist, then the hanger bearing moves up, and only after all this happens the car will start to move. This new Carbon Fiber (also available in aluminum) that uses a 1350 joint on one end and a Custom CV on the other will make the car feel more connected or more athletic. The response from the gas pedal will be more responsive and will increase 60ft times at the track. This shaft will require a small spacer installed under the front mount of the diff (which is as simple as removing the bolt and slipping it in) to ensure clearance on the rear section of the shaft. This is balanced like all shafts on The Driveshaft Shop’s 9500rpm balancer, so you know it’s done to the best standards available today.
