Steeda One-Piece Aluminum Driveshaft for 2005-2010 Mustang GTs.Steeda's aluminum driveshafts for the S197 Mustangs are a popular upgrade over the stock heavy two piece steel driveshaft. These driveshafts do not use a flange adapter like other versions which can contribute to vibration. Instead, they come with a completely new pinion flange which the driveshaft bolts to directly.
They have a tapered 3.5 to 4 inch design giving them extra clearance needed to avoid interference that can happen on lowered cars with full 4" shafts. Weighing 24lbs less than the factory GT model driveshaft this one piece driveshaft greatly reduces rotating mass giving you up to 2 tenths improvement in 1/4 mile performance!
