2021 gladiator eco diesel front bottoms out on stops! What’s the best copilot springs to fix the issue

[Kirkwill69]

What springs would be best for the eco diesel? Have steel front bumper and warn winch, 35” tires. When I hit a peed bump it bottoms out on the stops.

Get a lift kit. Mopar lift or any one of the half dozen discussed here. The added height gives you the clearance and better spring rates you need. Plus you are running 35's so a lift won't hurt.

Coil spacer + sumo springs bumpstops really helped mine. (Your results may vary)

It came with a lift kit on it when I pitched it, believe it’s 1.5-2.0” lift kit, has the fox shocks (factory) but speed bumps make it bottom out if I don’t go slow enough, which is almost a dead stop. Just looking to see what springs (front) everyone recommends, from what I’ve read the teraflex are good, but figured the form would be best bet since it’s a jeep forum.

I’m very happy with Clayton 3.5” diesel springs in front. I had the same while stock, frequently on the bump stops unless crawling. I think Clayton makes the same spring rate available with several ride height options, so you can pick the lift that suits you

I second the Clayton springs. They stopped my "bottoming out" completely.

Awesome! Appreciate the feedback guys.

I believe the diesel got the same springs as the gas engine from the factory, it's stupidly undersprung. I put on a 2.5" lift with the correct spring rate for a diesel with a steel bumper and winch; it rides much better, but I still need upgraded shocks to get it dialed.

There are a few brands out there that offer different lifts with different springs for the diesel. If a lift does not differentiate between diesel and gas, and doesn't offer a spring set specifically for the diesel I would avoid it.
You will probably hear nothing but good things about springs from AEV, Clayton, and MetalCloak (in alphabetical order). But I went with Evo. They offer diesel specific as well.
I also think going with better bumpstops is a good idea, The SumoSprings or MetalCloaks DuroSprings are a good option, but I went with hydraulic bumpstops from King for the front.

1.5 Clayton lift

If you're bottoming out the front despite already having lifted springs, then you might want to look at installing stiffer shocks. The factory Fox shocks are quite under dampened even when new, and they only get worse as they age. Something like a pair of Bilstein 5100 shocks of the appropriate length for your lift is what I'd recommend.

I have the Aev diesel HD springs in the truck along with with the teraflex 3 shocks and it’s never hit the bump stops. And I’m really heavy

Gents, thanks for those answers. First time I hit the front bumpstops on my new/to/me 2021 JtD was this weekend. It has the 2" Mopar w/fox shocks. Didn't happen at all at Moab last summer but the bottom of the end of a long driveway into the street. Big dip, same thud w/teeth shaking as my jlud does.

My 21 jluD does it alot and got jeep cares to recently replace my front bumpstops and shocks for $500.
So 20k more miles before im out of the aftermarket bumper to bumper warranty. Then I'll decide on a lift. Since I just got the new shocks, ive got an old 2" puk kit we took off my wife's 2020 JLU 2.0t, we put a 3.5" lift on it at 85k. Our butts had had enough of the pucks.

So both need better front bump stops.

I purchased a used 22 eco, no lift, Holstein 5100's, and 37's and when I 1st got it I was very worried I was going to be bottoming out but I have yet to bottom and have hit some dips and speed bumps faster than I should have.

With your existing lift I would talk to Clayton. I did the COR-1509150 springs which are 1.5” on JL Gas engines, but barely any lift on a diesel. I had the Mopar steel bumper, maximus3 plate, & 10K Warn. No lift with the springs but they stopped my bottoming on every speedbump.
