I have a 4" lift, 4.88s with stock axles. Thinking of upgrading to a set of SXs but I would have to go to 36x12.5s, is this gonna cause a huge increase in wear on a stock driveline?

JasonM is running 38"s on his cruiser. Not sure of the lift amount though.

36"s should be OK, I run 35"s on mine and I haven't had to many problems beyond broken birfields (That really would have broken with any size tire on there :eek:)

Do it.
Buy a set of bobby long's birfields and do not look back. I had no axle problems at moab.

My suspension is a simple springover with 2.5" shackles and 55 springs in the rear. I pulled the 4th main leaf out of the springpacks but after this weekend they are going back in.


Just get friendly with the sawzall......

SKIP THE 36 AND GET 38.5 ...

I RAN THEM WITH A SBC AND THE STOCK BIRF FRONT WITH NO PROBS...

OH YEAH 4" SUA WITH MINOR TRIMMING AND BUMPSTOPS...NOW IM SOA W STOCK SPRINGS AND TRYING TO MAKE IT LOWER

I'm not sure what size u should go for, but deffinitly get the sx's either 36-38 would be killer. and get stronger birfs.
