Need rear spring recommendation for JLR

[Reinen]

This looks like a pretty expensive solution to this problem. ? My 2 door sport is also sagging in the rear... I've added a hardtop, tailgate table, fridge and slider, cargo basket, bike rack on my spare. But, I'm really hoping there is a more economical solution? I also don't want a full lift - it is almost too tall for me to step into currently.

There is the AirLift 1000 air bags that you would insert into your rear springs. But I would only recommend that for on-road use or very light off-road. That was my first attempt at resolving my weight issue. I popped them on the first trail I took, which was a rocky moderate trail with a significant amount of bouncing.

I wonder if 4xe rear springs or diesel rear set would be an option for the OP to consider?

If your carrying enough of a load to sag it you need a different spring rate. Put all the spacers on it you want but it won't handle the load well. Not sure how much stiffer the diesel or 4xe springs are but that something to look into. Which ever you would do I would swap both front and rear so they match up height wise.

I think Clayton also makes a 1.5" spring. The good thing about going to an aftermarket spring is that their rated for the weight of a built jeep usually.

While on the Old Man Emu site, it appears they have a lot of individual springs available, although I’m wondering if they are cost effective since it appears they are all made in Australia. I haven’t had a chance to call them yet but will will provide an update on what I find out.

Please keep the data/suggestions coming! Hopefully it can help more people than just me.

I’d recommend calling Dirk at DPG Off-road if you have any questions about Old Man Emu springs. He is very knowledgeable and can put together a hybrid kit OME/JKS/Currie made just for you. I’ve bought 3 kits from him and have always been very impressed.

I was on the road for work this past week and didn't have time to do much with this, but it's on the list for this week. Here's a good comparison of why I'm so frustrated. This is my JLR (on the right) next to my daughters '22 JLUR. There's nothing inside the back of either Jeep, and the only two "notable" items on mine that should account for any sag are the bike rack and tailgate table. Plus, as I mentioned before, there are 1" spacers installed on mine too, so obviously without those it would be 1" lower yet.

FYI: measuring the shock lengths at ride height is a good way to compare.

Thanks! I will do that and report back.

Note, I don't know exactly how much, but the stock stance (rake) is different between the JL and JLU, at least per teraflex.

If you base it off of how TF does their 1.5" spacer lift, the stock rake front to rear is .5" higher front on the JL and .5" lower front on the JLU. That could mean that the difference is actually in the rear stock.

Another vote for Airlift airbags here.
I went camping on the weekend and weighed the loaded Jeep, 6,100lbs with me in it.
30 psi in the bags brought it back to unloaded height and although I was cruising anywhere from 50-65 MPH on a dirt road I never bottomed out once.

Thanks, and I have read about this as well. I can't comprehend why Jeep would ever do this, and I'm guessing they achieve this by a lower spring rate. That seems to be counterproductive to off-road capability, especially when loaded with camping gear, etc.

@Reinen mentioned popping air bags earlier in this thread, and that's the number one reason I'd avoid going down that path. I enjoy taking my Jeep off road, and have always felt air bags were probably better suited for minimal suspension articulation.

Only thing I can guess is that it’s related to the differences in rated towing and payload and potentially the impact of the wheelbase on load distribution.

The stock ride heights are all over the place... My JLR was stupid high in the front and would top-out the shocks on heavy acceleration (like a drag car).

Unbelievable! Fortunately my front seems to be where it should be, but the back is trying for a Carolina Squat.

I’ve been off-road numerous times fully flexed out and have never had an issue with the bags and never felt they limited suspension travel either.
I believe Airlift has a lifetime warranty on the bags as well.

edit: yup, lifetime warranty on the bags
