Mirfster Posted February 18, 2015 Share Posted February 18, 2015 Just was wondering if there was any signifigant differences in the years as far a bodies go? From what I understand (still learning) one could pretty much get all the options that came in a high trim (Eliminator) and put them in say the Base Model. I know that there were different bed sizes, but aside from that are there really any major differences that would make a new year ('91 -'92) more desirable as opposed to the earlier years? Thanks for any advice Link to comment Share on other sites More sharing options...

ggcnash Posted February 18, 2015 Share Posted February 18, 2015 Yea renix vs Chrysler system huge difference for most the Chrysler system is way more desirable and has less issues and more power in the h.o. Engine. There are guys on here that can go way more in depth and give more details good luck Link to comment Share on other sites More sharing options...

Pete M Posted February 18, 2015 Share Posted February 18, 2015 there are some minor differences earlier on, depending on what you want to do. the biggest is the change in the radiator area from 86 to 87+ the rad supports and hood latches changed. these (plus the firewall got a bit of a bump in it) were done to clear the new 4.0 engine going in. oh, and in 91 they changed up some of the front fascia/grill pieces and how they went together. there are some differences in the rear frame between shortbeds and long beds. that's all I can think of with respect to the body. these trucks are like lego. you can get a solid body and make it into the trim level you want if you can find the right pieces.

cruiser54 Posted February 19, 2015 Share Posted February 19, 2015 Yea renix vs Chrysler system huge difference for most the Chrysler system is way more desirable and has less issues and more power in the h.o. Engine. There are guys on here that can go way more in depth and give more details good luck HO myth buster Renix in 90 made 182 HP. HO in 91 made 190 HP. That's 8 HP difference. HO only made more HP than Renix at higher RPMs and not a bit more torque. HO had 58 mm throttle body versus a 52 mm throttle body on a Renix and also had a better design header. See where I'm going with this? The whole 8HP was not mostly from the head, but from the bigger TB and better exhaust manifold. Put a 60mm TB from www.strokedjeep.com on your present head, eliminate the "crush" in your headpipe with proper re-routing, and go for it. HO stands for Highly Overrated. __________________ Link to comment Share on other sites More sharing options...

Incommando Posted February 19, 2015 Share Posted February 19, 2015 I have owned both Renix and H.O. 4.0's. I prefer H.O. Renix has its fans but for most it is a PITA for those not familar with it. Got a scan tool? The OBD1 HO is a breeze. Spend the same money to upgrade the HO as you spend upgrading a Renix and you will still be that much ahead. The fact that you have to upgrade the Renix to equal the HO says it all. I don't care if it is throttle body size or exhaust or what; better is better. If it wasn't no one would be suggesting upgrades to level the playing field.... To each his own and like I said: it is just my preference. Link to comment Share on other sites More sharing options...

dasbulliwagen Posted February 19, 2015 Share Posted February 19, 2015 86 to 87 they also changed the way the header panel attaches. I dealt with this putting the 86 Waggy header assy on my 87. Not that big a deal but worth mentioning since you're asking about body differences. Link to comment Share on other sites More sharing options...

conker Posted February 19, 2015 Share Posted February 19, 2015 Number of grille slots after 1987, other than that I'm unsure. Unless that was a higher trim thing? My 87 has 8 slots, my 88 has 10. Link to comment Share on other sites More sharing options...
