new guy with rear spring question

Hi, i'm new to the wj jeeps, and i've been doing some research around here about the rear coils sagging. i measured mine, and i'm the same distance from fender to center hub on front and back, 18". from what i've read, i should have 19" in the rear. that being said, which is the better route to go, replacing the rear springs, or just adding new isolators that are .75" per unit? price isn't that important, $125 for a set of moog springs, or $40 for the lifted isolators. i have new shocks installed, and need to replace the sway bar bushings. i'm not looking to lift for off road, just for light duty trails, and hauling trailers/cargo. my wj has 146,000mi, 4.0l 4x4. thanks!

If your looking for a small lift, try seeing if you can find some up country springs. They were factory on some models, and gave about an inch more all around IIRC.

You could also just replace the isolators, as they tend to sag over time.

Best bet would be to do both.

I'd replace the coil spring isolators before you do spacers or shocks. $100 for all 8 of them and that will likely get back the half inch you're missing

i agree, upcountry.
check the classifieds and also check ebay.
rockauto.com is a GREAT place for those spring isolators and even sway bar bushings your looking for.
imho it would be very dumb to add spacers to spring isolators that are shot. replace them so once you decide that a budget boost is the direction you want, you would have already had you isolators done and will appreaciate it later.
Also for light duty trails 2" budget boost isnt all that big. you can also run oem length shocks on a budget boost theres one on the classifieds for $100 shipped.

i thought it was
stock front 18". rear 19"
upcountry 19" front. 20 rear

the wj front end is lower then the rear so numbers are not the same all around

You know I have researched this a fair bit myself and the fronts I agree are front 18", 19" if upcountry. But rears I believe is very debatable some say the front rake is 3/4 inch (at least leveling kits are this height) and some say 1/2 inch and some say 1 inch. My springs with original isolators are 17 5/8 front 18 1/2 rear. 18 1/4 with a full tank of gas. Hard to find the definitive answer.

If you are in there replacing springs, you might as well replace isolators as well. There's no point in putting new parts on top of worn out originals; you're not doing yourself any favors. My Jeep had Upcountry suspension which I took off when I lifted it. The original measurements showed that the collapsed isolators were responsible for 5/8" of sag and my sagging springs were responsible for 3/4" of sag.

On that note, I wouldn't recommend buying used Upcountry springs. It is highly likely that they are saggy just like your original springs. If you want to stay stock, that $125 set of Moog springs sounds like a great deal. Add about $100 for isolators from RockAuto and then the job will be done RIGHT.

Those won't fit a WJ. WJs use different spring seats than the XJ/ZJ/TJ (which are all the same)

They CAN'T fit both the TJ/ZJ/XJ configuration AND the WJ configuration AND the WK configuration. Those are three totally different applications. You could apply common sense, or you could buy them and waste $40. I'm just trying to help here.

Why not just purchase from Kolak and then you will get good advice and customer service and the right stuff. Just do a member search and pm him.
