Mopar Axles and Racing Slicks
Don't waste your time on stock spline stuff. Go 35 spline right away at that power. I left soft and chopped a stock spline Dr. Diff right off in an OLLLD stock posi unit lol. Now it's all 35 spline and on a spool, trouble free.
Not bashing Cass, the new axles came from him to, I've bought around 5 sets in the last 2 years for our own projects.
