The GT-R Pro-Level Axle Kit feature a direct fit outer CV made from a high grade proprietary material, Porsche style 108mm CV's on both ends but we have upgraded them to use our signature 30 spline bars with billet 4340 cages, our aerospace quality torsional center bars that twist significantly more than a factory unit, allowing them to absorb a great deal of the shock produced by high horsepower applications. The axle kit also includes precision billet adapter plates with hardware to mount to the factory differential stubs. Price listed is for both axles.
