have a set of NIB 31 spline GKN half shafts. I paid $1300+ shipping looking to get $950+shipping. here is some info on them.
Features:
Improved design and material with higher hp/torque capacity, and able to withstand more abuse than the factory half-shafts.
Bench testing has shown an overall strength increase of 32% over factory.
The shafts themselves are made from 4340 gun drilled aircraft-grade steel and then honed.
Both the inner and outer CV joints have been upgraded for durability, which is typically the breaking point of a factory shaft.
Both the inner and outer cages are made of 4340 steel, which is 200% stronger than factory.
The joint outer housings are cryogenically treated and contain cooling fins, which also provide some weight reduction.
The wheel and differential end joint is a 2-piece design, which helps in joint and/or seal replacement.
With this added strength, each half-shaft weighs only 3.2 lbs. more than a factory half-shaft(2003-2004 Cobra)!!!
Warranted to be free from manufacturers defects.
the 2001-2004 IRS Cobra which feature a 31-spline inner and 28-spline outer.
Similar designs currently be used on 750+ hp Viper's!!!
