Gladiator Rubicon Diesel Bottom Out issue

[redfish]

I am adding Rubi springs from a 2021 Rubi Gas with steel bumper from factory and front spring are 6363AA and 6362AA, so at least different numbers

Well said. I wonder if the Mopar 2” would fix the problem.

Not unless you can get a kit with a increased spring rate. The longer spring just gives the wheel more travel aka more time to absorb the impact, longer springs with the same rate will just make the truck feel mushy and rolly cause now the wheels are moving up and down further and the issue of dispersing the wheel travel energy in a controlled manner is still not addressed.

You would do well to research companies that sell springs for trucks and see if they offer any uprated springs for the added weight of the diesel. These companies should have spring rate charts of oem rates and recommend a alternative rate for upfront.

Apparently Mopar part made a specific kit for the diesel.

Well that is good news
Anyone compare part numbers of front springs of gasser and the oil burner?

I hope they are different, same should go for the shocks. I hope the fox shocks on the front of gasser ruby are different than the part number of a diesel ruby. Will know soon enough when my jtrd shows up and I can look at my buddies gasser jtr.

Talking to Deaver springs or eibach might help. See what they know, they have equipment to measure spring rates and should have oem info on file

If you're asking about the part numbers of the Mopar 2" lift, they are definitely different for both springs and shocks:

In my experience as a service tech:

"........" sucks, fix it now"

"I've been here twice for this same problem, FIX IT NOW!"

"My payment...er, uh, I PAID CASH FOR THIS POS!"

"The FORUM said that >>>>>>>>>>"!"

"Bransford told me that I should've bought a TJ!"

It bottoms out. So do the porn teenies. You paid 69k. So did the porn teenies. You expect more from your dollar. Well, so did that porn teenie.

The mopar 2” lift solved my problem.

what I had to slow to 20, I now can take 35+

It would be really interesting to see if a non-diesel is using the same part. Did they not factor in the weight difference?

I have taken Diesel springs off and they are thicker and taller then the gas Gladiator.
But I don't understand what your pic is supposed to show us!
what is happening that you are bottoming out?
Is it a load in the bed?
Is it going over a bump at a certain speed?
Sorry for all the questions, just trying to figure out the problem, instead of a post that just looks like somebody wanting to bash Jeep

No load. This is my 6th Jeep, all I have ever driven, no bashing. Extremely annoying to bottom out on a tiny pothole. Never happened on my 2018 JL. Picture was for someone who wanted the part number, read thread from beginning.

So... the Diesel DOES or DOES NOT have different springs than the rest of the rigs?

 

[CrazyCooter]

68506377AA and 68506378AA front springs in my Rubi Eco Gladdy

By looking through all the front and rear springs (allmoparparts.com) I have found 0 trim specific springs. They all are listed for all trim levels. Some are listed 2021 only, rest are listed 2020-2021.

What year?
Diesel, okay.
Rubicon, okay.
Factory steel bumper or no?
Speed?
Types of bumps/terrain/potholes/etc.?
What are the part numbers for the springs you have, both of them?

I am with the OP. I love my sarge green rubi diesel, but it definitely bottoms out up front on moderate bumps, potholes, etc. I have the stock bumper and nothing added at this point. That’s one of my few complaints so far…

OK, I would go to the dealer and talk to the Service Mgr and see if he can get a new one off the lot and compare with a diesel to see if it does the same thing. If not then they will order new springs.
I have driven a handful of the JT Diesels and we have lifted a lot and I have not noticed that problem. Next Diesel we get I will look for some pot holes
