3/4 ton Grand Cherokee

Has anyone replaced the factory rear springs on a 99-04 Grand Cherokee for a heavy duty spring of some sort. I am dong some towing this summer and want a bit beefier rear susp.

air bags.

but, the grand is limited in its towing ability by its wheelbase and not being full frame more than it's suspension and motor.

As Ratmonkey said, one of the biggest limits to the towing capacity of a Grand is its size and weight. Being unibody doesn't help either.

Its not a matter of only the springs. It's a matter of the unibody structure, axles, etc.

The GC is rated at 5000 pounds towing, what more do you need?

Why don't you just try loading your truck differently on the trailer to reduce your tongue weight?

if its just a tongue weight issue, get an equalizer hitch, you should have one anyways with such a short wheel base vehicle

you're not towing it right. you need a weight distribution hitch and/or a much better trailer for what you're trying to do.

I didnt ask if i "was doing it right", I was only wondering about heavier springs. A new trailer will cost 2-3k as opposed to new springs which will run $100-300. Now you can see why I was pondering the idea. I guess if noone knows Ill ask around another jeep forum,

with the V8, your capacity is 6500#s with 750#s tongue weight, with weight distribution hitch. WJ jeeps says 25' trailer maximum. I think you would be okay with the weight distribution hitch, which you should be using on any vehicle with that much weight anyways.

The OME HD springs, or air bags in the rear springs would help a bit. Definitely get a weight distribution hitch. The WJ V8 is rated to tow 6500 pounds, with 750 pounds max tongue weight. I'd also want trailer brakes if you don't already have them. It should do fine with the weight as long as you have it set up right.

i know this is a long shot and ill get some crap for saying it, but if you truly want to keep your jeep and beef up the rear susp, consider converting to the rear leaf springs? may be a better set up for towing than coils, but i could be wrong
