Steeda Aluminum One-Piece Driveshaft for 2011-2014 GT Mustangs.
Steeda's aluminum driveshafts for the S197 Mustangs are some of the best aluminum one-piece driveshafts available! These driveshafts do not use a flange adapter like competitors versions which can contribute to vibration. Instead they come with a completely new pinion flange which the driveshaft directly bolts to.
The GT model driveshafts are a tapered 3.5" to 4" 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!
