In the last year I have broke 2 stock 32 spline rear outputs in my rig. One in the sand, the other doing a truck pull. Both broke clean at the end of the splines for the yoke. I can only find 2 companies that make a upgraded shaft. One is 1.5 35 spline(Juggernaut NP205 Rear Output Shaft - 35 Spline), the other is a 1.75 34 spline(Titan Series NP205 REAR OUTPUT HD Kit). Anyone have any personal experience with either of these, or any other options??
