I am acquiring a 91 Mj long bed 6 cyl 5 speed for a daily driver/show truck project. I am going to be doing alot of different things to "update" this to a newer looking truck, such as the 98 front clip, interior etc etc. But one of the other things i am going to do is put a set of 2" coil spacers in with a set of take off 04 tj coils and some TNT 1.5" boomerang shackles to give it enough room to comfortably fit 30s for now and possibly 31 in the future if i feel like trimming (this is a street truck so i am not worried about flex)
I have owned 4 xjs and modded them plenty but ive never worked with an MJ before. I am also getting a 29 spline 8.25 with sprig under perches welded to it and 3:55's so it should have plenty of gear for 30s or 31s.
What my plans are as follows.
Swap in 8.25, new rear drums for now, Future KJ liberty 8.25 disc swap. Add the shackles and coil spacers.
My concerns are about that rear brake thingy attached to the axle, I should be able to use that on the 8.25 but how does lifting the truck effect that?
Also can i remove it completely and swap in a newer brake booster and proportioning valve?
When i did the rear disc swap on my xj i used a ZJ prop valve, so can i swap in my old XJ prop valve?
Basically whats the deal with the brakes on this thing? For now it will be stock front with 8.25 rear and drums, then one day rear discs.
