AutoMoto Posted November 24, 2009 Share Posted November 24, 2009 I'm looking for a list of mods for our MJs that are most common, and functional. My goal is to upgrade my '88, to a modern truck, while using the most OEM Jeep parts possible. Some things I've picked up. Brake booster (why?) KJ rear discs brakes (stopping power!) Bucket seats (more room?) Help me figure out the rest Link to comment Share on other sites More sharing options...
mvusse Posted November 24, 2009 Share Posted November 24, 2009 Brake booster (why?) Better stopping power. Brake pressure with the stock booster is marginal at best. D44 or 29 spline 8.25" rear axle. Link to comment Share on other sites More sharing options...

dunl Posted November 24, 2009 Share Posted November 24, 2009 I've started a list of "junkyard swaps" that can be used for upgrading (not mine, just copied and pasted): http://reddeerjeep.com/forum/phpBB3/vie ... ?f=9&t=782 Do your reseach and use your own discretion. :D (sorry for the slow loading time...we need to change servers. :) ) Link to comment Share on other sites More sharing options...

AutoMoto Posted November 25, 2009 Author Share Posted November 25, 2009 :eek: I didn't know there was this much interchangeability with our trucks!

Pete M Posted November 25, 2009 Share Posted November 25, 2009 best advice is "ask before you buy". We'll do our best to steer you right. :cheers: there are plenty of minor changes in the details that can cause headaches. Link to comment Share on other sites More sharing options...

CWLONGSHOT Posted November 26, 2009 Share Posted November 26, 2009 I like to swap in the XJ under dash lights and swap OUT the hokey cab lites in the B pillars to modern style like has been out lined a couple times here. Loose the rear prop valve and swap in the 96+XJ booster and MC. Also do the headlight wire loom upgrade along with some good H4 lenses and bulbs. HUGE improvement!!!

Eagle Posted November 26, 2009 Share Posted November 26, 2009 the 97 + header isnt really "interchangable" i don't think, but it doesnt take much to put it on It is a bolt on. The header is a bolt-on, but the upper-outer corners are more rounded and don't match the sort of beveled profile of the early fenders. If you replace the fenders at the same time, that's not an issue. To imply that you can bolt on the header to the original fenders is misleading. It can be done, but it requires some preparation. Basically, you fill in the hollow spaces in the back of the upper-outer corners of the header with bondo. Then you bolt on the header and shave the corners to match the profile of the fenders. There's also a bit of work involved in mating the new style side marker lights to the older wiring harness. I think anyone considering what can/should be done to an MJ in the context of this thread needs to first sit back and define the distinction between "upgrade" (make it better) and "change" (make it different). There are a LOT of things you can change using bolt-on or near-bolt-on parts, but in many cases (such as the header, for example) they don't add any functionality, they don't work any different or better than the old parts, so they aren't "upgrades." If the goal is to make the vehicle more comfortable, more serviceable, and/or more convenient, it's important to zero in on the changes that actually accomplish one or more of those goals, and not waste money on stuff that's "different" but not "better."
