Product Details

This TrakMotive SB-8100 CV axle shaft is built for Subaru Impreza rear axle service where a direct replacement is needed for the rear left or rear right position. The axle uses a 25-spline inboard configuration, 27 outboard splines, and a conventional outboard joint design. TrakMotive identifies this axle as a new part and notes that ABS axles fit non-ABS applications unless otherwise noted. The SB-8100 also cross-references Cardone New 66-7378 and Cardone Reman 60-7378 for the same application.
