It will maintain the ride quality while unladen and help with capacity. I'll post up what I find out.

the question in my mind is how to handle the front hydraulic bump stops. Im not sure how those will relocate to accommodate the lift.

fabtech is working on a mojave specific kit, so im waiting to see how that turns out.

Not trying to side track this thread but what mud flaps are you running?
They look great.

I run Air Lift air bags in my F-350 for carrying heavier loads and they work great. It allows me to have a normal ride when empty. We took our truck with the Hallmark Expedition camper on it to Alaska this summer and ran the Haul road to Deadhorse which is a 500 mile each way gravel road as well as a bunch of other gravel roads, some of which were pretty rough and the air bags worked remarkably well.

The flaps are Cloud Rider.

The hydraulic bump stops do not need to be relocated. A 2" spring spacer fits around the base of the hydraulic bump stop, and a 2" bump stop spacer is added to the bump stop pad on the axle, just like on a non-Mojave lift.

I just discovered this as you posted it as well. Thanks for clarifying for us though...you know a lot more about it than i do, for sure.

Frustrating.

i called Fox suspension to ask about the specs on the mojave shock. I got “huh. Yeah totally bruh. Its what you get after 3 years of engineering work. Those things are rad” sigh. Best i could get was “dont lift it more than an inch” (off center of stock) but that was dude man swag’ing, i felt. There were no specs to be shared or discussed and im not entirely convinced he wasnt thinking rubicon for at least half the conversation.

I reached out to a suspension shop to start down the path of getting the Mojave suspension assessed.

1- where is the bypass zone, and how far off center can we lift or squish before we are outside of it

2- how well will the valving handle increased spring rates before it gets bouncy; and how elaborate is revalving(since these are rebuildable shocks!). I speculate the valving is sufficient to accommodate most of the overlanding type springs available.

what we need is a company like @Clayton Off Road or other vendor to make an overland type kit with shock extensions that match their spring height, and possibly offer a revalving service. Or we just need to figure the shocks out and piece everything together from a hodge podge of vendors.

if it goes the latter, knowing where the bypass zone is of the shock will let us pick the right parts to lift the suspension correctly. It becomes more tricky with springs than it does spacers, because a ”2.5inches of lift” spring is 2.5” over what? Sport? Rubicon? Not mojave though. So lifting with a spring means a careful selection of shock extension. Be nice to get a slight rake for load carrying too.

its frustrating to watch vendors release their lift kits and accessories for Rubicon’s before the jeep itself is released; and then act like a set of good shocks from the factory broke the matrix. Lifting a mojave isnt hard. Its the same math problem as any other jeep, the measurements are just slightly different.

Fox did the same to me. We were communicating via email, but then the guy ghosted me. Good work though. Interested in learning what you can find out.

I am waiting for all the parts to come in for my Mojave. I’m doing 1.5” teraflex space and bump stop for the front. Also doing a fatbobs garage 1.5” rear spacer lift along with extended upper rear bump stop. To ensure that the shocks are not to far out of parameters I am installing Rubicon express shock extension brackets front and rear. If need be I will order either longer sway bar links or a sway bar spacer. By doing all of this you are keep the suspension in factory parameters but just 1.5” taller. My thought is the Mojave sits fairly level now and I would like to keep it that way.

Did you end up getting this set up installed? Looking at doing something very similar, curious how it turned out? What you would do differently if anything?

@JET222

IMO the answer to lifting the Mojave is a spacer lift and geometry correction brackets like AEV that extends the use of the factory shocks. I think the AEV lift will actually fit, as folks are finding other spacer lifts/shock extensions actually do fit the Mojave.

Re: people not understanding why we would want a suspension lift on the mojave....im confused as to why this even needs an explanation. We're adding load, we're adding bigger tires, just like other jeeps. Spacer and shock extension lifts work great, and will maintain the awesome shocks we have. Plenty of damping, plenty of control, plenty of performance. compressing the front 1/2" under winch and bumper i dont think is a big deal. Remember we are already higher than the rubicon by an 1" and our front springs are stiffer. Any concern about "Being outside the bypass zone" is nothing but conjecture at this point, or people who desperately want the mojave suspension to be inadequate. What we need is either: A- Fox to release the details of the shocks or B- someone to put the shocks on a shock dyno and get the data. My guess? Theyre fine. That there is plenty of allowance in the bypass zone, and sufficient damping to handle some additional spring rate for those choosing to do it. The other option is to play with the math. if your bumper and winch compress your front springs 1/2 inch, figure out how much they compress a rubicon spring. 3/4 inch? you could go to a rubi spring, 2" spacer and that would put you within 1/4-1/2" of stock. You'd fit a 35" tire just fine with no shock extension. Or, you could go with a 3.5" lift spring of a slightly higher spring rate and a 2" shock extension and be within a 1/4-1/2" as well. (assuming the spring lifts as advertised) you have to check what the lift is advertised as 2.5" for a sport? for a rubicon? with what added weight? etc.

As it sits, I dont think anyone knows FOR SURE:
A:
-what is the up travel of the mojave shock
-what is the droop travel of the mojave shock
-what is the overall length fully extended
-overall length fully compressed
-compare all these against the rubicon shock
B:
-where in the travel is the bypass zone active within the mojave shock



edit: I had a pallet box of firewood in my bed yesterday and it compressed quite a bit too. I'm stopping by a shop today or tomorrow to see about getting Air Lift 1000 air springs installed into the rear. It will maintain the ride quality while unladen and help with capacity. I'll post up what I find out.

Ive heard these springs cause an issue off road, but I have a good overlanding buddy that runs someones airsprings inside his rear coils on his lifted/long travel FJ and he hasnt had an issue. Been on the truck for a few years now too.

Do you know if anyone ever got the shocks in a dyno? Did you ever put the airlift springs on?

FCA is doing a buyback of my Rubicon in a few weeks, and I am considering a Mojave as a replacement. Air Lift helped immensely for my RLD + RTT. Was sagging and swaying pretty bad before I added the Air Lift. Wanting to do the same on the Mojave.

I didnt. It was $1600 id have to pay the shop to do it. A bunch of vendors here wanted the data but none of them were willing to offset the cost. It was basically “yeah we’ll take all the data, and might be able to give you a discount on some parts”

I said no thanks.

That RLD cap with a rtt is going to be heavy, and the Mojave has softer springs than the rubicon does, so youll need to do the same approach.

So you didn’t end up putting airlift on the rear springs?

I havent yet. I havent found ive needed them yet with the fabtech springs, but ilp be running a lw rtt and a rack not a heavier cap.

 

[jnord209]

Anyone know if the Mojave spring are the same as the Mopar 2” lift springs? I have a Mojave with the Daystar 2” leveling lift plus a .75” rear puck and the Airlift bags. It sat level and rode nice with a steel front bumper on the front and with a ARE cap and Versahual carrier on the back. I just added a winch and a Blue Ox flat towing base plate and it lowered the front by about .75”. I’m wondering if swapping to the Mopar springs will lift front back up.

I don't know if I can help because I don't know much when it comes to this. What I do know is that when I loaded my stock Mojave with a roof top tent and all my camping equipment in the back, I had a lot of sag. So Dobson sent me some springs to install in the back. When I had them installed, I also installed a new front bumper with a winch. So now my truck sits up high in the back. Which I don't mind when I am just driving around. Then they had me load up my camping equipment and send them photos and they are sending my springs cut to fit my front so my truck is level when I have my roof top tent on. The lift from the springs was about 2". In fact you can see the what it looks like with the spring in the back and nothing in the front and no camping equipment from my member picture.

How did the Dobson springs affect the ride? I had to travel to a Basketball game this week, and ended up in rural Eastern WA Palouse country and found a long stretch of "unimproved" remote dirt roads that I LOVED flying down in the Mojave... The Mojave shines on high speed terrain like this and it was a BLAST to drive....
