Those Who Swapped to Rubicon Shocks/Springs

[chithead]

I haven't swapped the rear springs yet, still running the stock Sport - but can definitely tell they are the weak link compared to the Rubicon spring swap up front.

Still wondering if going to the Mojave would be better (have a set of those at the house too) - check out the comparison I did between (left to right) Rubicon, Mojave, and Sport - the picture with two springs is the Rubicon vs Mojave

I have max tow rear springs and don't find the rear bouncy at all.

I have max tow rear springs under my Overland as well - the bouncy part means the shock is not dampening the spring oscillations. When my truck goes over a hump or bump instead of down, up, settle, stop or up, down, settle, stop, I get up down up down settle.
If this was a 10 year old car coming to me for diagnosis, I'd tell the customer the shocks needed to be replaced. They don't do a good job.
The springs are more harsh than stock Overland springs, the Rubicon shocks are not as good as the stock Overland shocks at stopping spring oscillations.

The max tow springs under the rear of my Overland were a lot shorter than the stock overland rear springs and yet the rear of my truck didn't drop enough to measure.
There was over an inch difference. The max two springs slipped right in with room to spare - I had to work to get the Overland springs out.

No doubt - I was surprised to see the Sport springs being taller, but you can tell the coils are much thinner than the Rubicon, and WAY thinner than the Mojave. Friend of mine said he didn't know if pairing the Mojave springs with the Rubicon shocks was a good idea, could make for a very uncomfortable ride - so I installed the Rubicon springs instead. Now thinking about trying the Mojave at least just to have a comparison.

Interesting. I lost the rear ended bounce after the swap. It just feels more solid. You feel bumps more, but it reacts and is done. No more bouncing up and down once or twice after hitting a bump. I don’t know my spring rates or part numbers, but they came off of a Launch Edition.

I’m not sure why it would matter, but it’s a 2020 Overland 3.6l/auto, hard top and every option but the advanced safety group.

This is my experience switching to the Fox shocks too. Initial hit is soft and then firms up and dampens as it travels, I don't get the harsh hit and rebound like the stock overland shocks did. Seems more suited to soaking up bumps on a woopy trail at speed.

There is a speed bump in my work parking lot that I no longer slow down for. On the stock shocks it forced the rear end to jump, now it just takes it no problem. (I know the speed bump is there for a reason, but in pandemic times my parking lot is a ghost town).

I've seen a couple write ups from those that did just Mojave springs and they appear to be favorable. I would be interested to hear about your results as well. From what I recall the Mojave front springs added another 1/2" or so over the Rubi front springs. So that may give you the result you were hoping for with the Rubi ones.

Honestly now that I'm about 6 months and about 4k miles into the Rubi springs and shock swap, they've grown on me. I still like the way it sits now vs the stock JTO springs. That small difference in height IMO just looks better. One thing I did do though was add some more weight in the rear. I had noticed how much better I felt the ride was with a small load of a couple bags of mulch or dog food that I looked at ways I could add some more weight. Since Rubis have the added weight of the bed rails, extra tow hook, and steel rear bumper. I figured this may be part of the ride difference. I did add the extra OEM tow hook, which was only a few pounds, and replaced the factory spare with a matching size. That added about 20lbs+/- in the rear overall and it honestly helped with my complaint about the rear bucking.

I'm still interested in possibly adding a rear steel bumper and the bed rails too if it would help a little more. I also added a Rubi front steel skid plate as well too. I don't know if it made a difference, but overall the ride feels better. Now the question is did the changes do anything or did everything just settle out? Or alternatively is it all just in my mind?

pls do this

Put the Mojave springs on all the way around about 3 months ago. Didn't gain any height versus the Rubicon with steel bumper and hard top springs, but definitely firmed up the ride and such. I like it better actually. Added a 2.5" Rough Country spacer lift up front though, and now she sits higher than the rear. Debating on where to go next. Thought about the 1.35" ICON rear spacers to level her back out, but for the price, it wouldn't be much more to just go with new springs in the back. And if doing that, why not do an all spring lift up front too.

I often wonder if the diesel Rubicon front springs are taller to accommodate the addition of the different motor. I wondered if I could do that Instead of spacers.

Damn decisions. Why do we complicate our lives so much?
Never mind, rhetorical question.........
I'm facing similar - Overland with max tow rear springs, the lighter Rubicon front springs up front, Rubicon fox shocks all the way around, and Daystar spacer lift (.75") all around. Gained about 1" both ends after adding a bazillion pounds of winch and bumper and skid plate.
So, do I move that stuff over to the new Overland, or, do I do something different, skip the front Rubicon springs and just go with 1.5" spacers up front?
Similar for rear - I tow and haul so wanted less butt drag when loaded with stuff - max tow springs helped a ton - but are there better options?
Dang, I had deciding stuff like this.
So - I keep watching posts like this one.......

Are they taller, higher rate, or combination of all of the above?
On the other hand - looks like the STOCK front Rubicon diesel springs aren't holding up their end (pun intended)

Great point! (Bottoming out) Man, you’re pretty quippy today.?

I feel that struggle. I’m just going to pull the trigger on the 1.5” Teraflex. Seems more logical for me After the “bazillion“ pounds I added this weekend. I do a lot of towing.

Maybe the meds are kicking in LOL
My wife HATES it, and I think one reason she hates it when I get together with my brothers is that my youngest brother is 10 times worse than me with the cracks and quips. Drives my wife nuts.

I just picked up a set of Gladiator Rubicon FOX shocks with a whopping 300 miles on them. I also bought a new FOX 2.0 IFP steering stabilizer as well. Ours is a High Altitude Diesel. I'll be interesting to see how it feels after swapping everything out probably this weekend.
