Currie LJ 9131RH3P on TJ

I have a Body Armor rear bumper/tire/ dual fuel can carrier on my TJR with 4" Currie 9130 springs and 2" spacer/isolators but it's still not quite the right height with my 35" BFG MT's. Currie says the 9131RH3P 's are 1/2" taller and should hold more weight. Anybody running these with a similar setup?

I'm thinking of using the spacers with the 9131's too, as with gear and the 24.5 gallon Genright I'm pretty heavy.

I am using them on my TJ with only a 35" spare, and steel bumper/carrier. They netted me 5.5". The downside though is the low spring rate, so its an uphill battle with all your heavy gear. Have you thought of losing weight? Most will probably agree that fuel cans are not needed.

I use both fuel cans when I am in Mexico as I need 92 octane and mexican gasoline is universally considered poor quality. i throw misfire codes with US 89 octane. The Body Armor bumper is a tank for sure, probably 125lbs easy but it has laughed at every rock I have bashed it with and love how it grounds my CB antenna. Normally I carry one full can and a fuel can tool box with recovery gear in it. I guess they do not make the bumper anymore.

Mine also has Currie LJ rears. Though they are a carry over from when the Jeep was much heavier than it is now.

If the Jeep is throwing codes with US89 octane, there is something going on with your engine.

The PO used a programmer that didn't make it to me and/or possible head work idk. A few shops suggested trying that first and no codes since I made the change. She runs great

The dealer can override any programmer and get it back to stock if you like. That would allow you to start from square one. Might cost you a bit. I took mine in shortly after I got it to have the latest software update and they did not charge me at all.

As far as sagging under the extra weight maybe it’s time for airbags.

Not really looking to do anything to the motor anytime soon, she only has 74k and I'm very happy with the power since I regeared. This is not a daily driver so the extra fuel cost isn't an issue; I guess I don't really need to know *why* she wants higher octane. If I had extra cash I might consider a crate stroker motor and would be replacing everything anyway.

I wasn't sure if air bags would hold up to rock crawling abuse, never seen anyone put them on a Jeep. It would be an easy solution as my tank and manifold is mounted to the left of the driveshaft.

Thanks I will have to make some calls and compare. I only tow a Hobie 16 about two miles to the beach but the receiver extension I have to bolt on adds another 20 lbs easy. I could see a tent trailer in my future too.

I did the same swap last month. The initial gain was about 3/4" however after first trip, the gain turned to loss of about a 1/4". BUT, the ride was way better.



Here you can see the 1/2" donut/spacer I cut to add 1/2", above spring, below upper spring mount.

Ask about the shock travel bias from ride height. Is it split 50/50?

quality bags will hold up fine off road.

Yep, noticeable by my passengers, one has spinal stenosis.

Same shocks, which are junk/leaking.

My impression was this was about springs???

How does shock or shock bias play into it?

Are you jealous of my forklift?
