Yes I'm on a budget but I don't want junk....

Thanks All!!


I have. They work very well.

We use them with a spool in a 3,700 lbs. street car in a Dana 60. It's seen 1.36 60 ft. times and we beat on the car regularly.

I would highly recommend getting them minus the garbage 1/2" studs they come with! We bent them as well. We put in Strange studs and all has been fine since.


30 or 35 spline spool?
Any difference in strength of them?



There is a substantial difference between 30 & 35 spline axles. I know of at least one manufacturer that shows a comparison, but don't recall which one.

FYI -35 spline 8 3/4" and Dana 60 are basically the same! But Dana 60 has the 40 spline option with 5/8" studs if that's a big concern.
