Can't compare equals.
I have a Spartan in my front Dana60 it was easy to install and works great.
I also had an Aussie in my Dana30 worked great but I broke the pins on 33" swampers. When broke it locked solid and I used it that way for a while before replacing the pins.
I like the design changes to the pins and springs on the Spartan, I will buy again if they release one for the rear 60.:thumb:
