Who Re-valves Mojave Fox Shocks ???

[msiminoff]

Can you measure how much shaft you have exposed on the rear so I can compare?

Okay the rain finally let up...
There is (approximately) 4.5" of shaft exposed and the eye-to-eye shock length is (almost exactly) 22.125".

My JTM is sitting very very close to factory ride height. This is with stock springs and 1.5" spacers at all 4 corners, GFC camper on, & a full tank of fuel. No passengers, no extra camping gear.

Note sure how relevant this is, but visually the truck appears to me to be level.... no rake, no squat. in the photo below I did my best to take the shot level and square to the Jeep. I added the cyan reference lines (all parallel to each other) to help me get a sense for "how level does it look".

Thanks for all of the input so far. Will let y'all know how it goes with Desert Speed.

Perhaps doing something with springs is first before the shocks…Jack

Thanks Jack! I assume that the Max Tow springs are higher rate than the JTM's?? I don't follow why you'd want to increase the spring rate and not also increase damping? Please enlighten me.

@CrazyCooter should be able to do that for you?

Tony does cool stuff! However my understanding is that he has been focusing on JTR's with Fox 2.5's and SDI E-Clik's (maybe I'm wrong about that?)... The Mojave/Fox internal bypass socks are a completely different animal.

Thanks for the tag guys!

To answer the question.......Can I do Mojave shocks. Yes......no doubt I could re-valve Mojave shocks, but I haven't had any in hand yet. To do the job right in that tuning the individual ride zones, I would assume the side reed shims would need to be swapped and I haven't added any of those to the collection as of yet.

Also something I picked out quickly here.......It was assumed that we ONLY work on SDI or Fox 2.5's. While I personally have the most experience with those platforms on the JT's since that's what I personally own and drive at least weekly, We have been working on many brands, sizes, and vehicle platforms!

We have also been putting many rebuild kits in stock and adding to the shim collections as I see them come in more regularly for fast turnaround. The locals are loving the reality of dropping off something like a Taco at 8am and returning to pick it up same afternoon with 4 rebuilt/re-valved shocks!

For example.....When you buy a tuned Fox or SDi from me that has been on my own truck, you are getting a ultra badass refined product because I have spent 1000's of hours testing and refining for all the small irritations I wanted gone. That doesn't mean that with the right feedback from the user that I can't create something that 85-95% badass for you, it just requires good feedback and maybe some video for reference.

Some of the shock/fork brands I have serviced include Elka, Fox, KYB, King, Walker Evans, Falcon, Icon, SDi, Afco, WP, and Showa on vehicle brands Mercedes, Jeep, Ford, Ram Dodge, Can Am, KTM, Husqvarna, Toyota, Honda, Yamaha, Chevy/GMC, Polaris, and more.....The database just keeps growing weekly!

For the most part same principals but sometimes different methods between the brands!

I'm also bringing in some help this month who has worked with us in the past and is a serious enthusiast for anything mechanical and especially off road! He will like before handle probably 80-90% of the local shop work, so that will hopefully free me up for some more development on other platforms. A shock dyno is looking more likely by the day and that will make tuning over the phone a lot easier.

Please update us with your experience with Desert Speed and how the work changed you truck's dynamics!

the rear springs are soft AF if you don't have the tow package

The tow package has a different part # for rear springs?

Yes

 

[ecidiego]

Yes

Thanks. More reason for me to buy the OEM 2024 Mojave X springs sooner rather than later... I've added the OEM hitch, front, and rear steel bumpers.

Yeah the 24s have new springs all around cus the tow package is standard now

Got it - and the X has different springs than the non-X too, so I can only ASSume it's because of the steel bumpers. The shock part #s are the same as all Mojaves.

Yes sir

Curious to see the part number for the '24 plus Mojaves. I ordered my '23 with the tow package.....will the numbers match?

Mojave X springs:

68607513AB
68607529AA

Rubicon X shares the front spring ( top # ) but Mojave X has a unique rear. The "regular" 2024 Mojave has different part #s.

Ok, I will check the part numbers when I get home; i have the OEM springs sitting and waiting to be sold

finally got to measure mine. I have 6.25" of exposed shaft. with a 3/4 spacer. So I'm confused. I'm riding with a quarter inch of rake. Also can u explain what you meant by "riding in the bypass zone" is that a weigh thing or shaft position thing? Your rig looks awesome BTW.

Also can u explain what you meant by "riding in the bypass zone" is that a weigh thing or shaft position thing?

TLDR; the "bypass zone" is a shock shaft (piston) position thing.

The bypass zone is a range at the center of piston travel where shock fluid is able to flow around ("bypass") the shim stack in the piston through the space between the inner and outer shock tubes and recirculate between the top & bottom of the shock; it's not a free-flow per se, there are ports and reed valves, but it provides a much higher flow rate than can pass through the valves in the piston. This allows the shock to have a soft (read: very comfortable) ride in the center of the stroke and still have plenty of damping at each end of the stroke to prevent topping or bottoming out.

The Mojave's Fox internal bypass shocks are the reason that, right off the showroom floor, the JTM's ride is so frikkin' amazing both on and off road (yes spring rate matters, but the plush ride due to the shocks). Lots of people make the mistake of a) lifting their JTM without adding shock extension brackets (this would cause the shock piston to be extended below the bypass zone), and/or b) swapping out the Fox shocks for one of the other brands which don't have a bypass circuit, and/or c) changing to higher rate springs that the stock shocks can't effectively damp, or d) like me they add a bunch of weight...and then we wonder/complain about our trucks having crappy ride quality.

Unfortunately I don't yet know the exact sizes/location/valves of the bypass ports in the Fox/Mojave... Fox and all of the shock builders have been pretty tight lipped about it. This is why I'm looking for a shop that specifically has experience with the Mojave shocks.

Your JTM looks awesome too!

The zones are piston location sensitive.

There are tubes within your external tubes that have holes machined in them which are covered my spring steel shims that allow for a controlled oil leak around the piston holes.

Say your shock was setup for 4 zones.........With the shock fully extended all 3 leaks in the tube and the piston come into play are subject to fluid flow. As the piston travels past the first leak, you now have only 2 leaks and the piston, progressing to the end of travel (and increasing damping) where there are 0 leaks flowing in the tube because they are on the rebound side of the piston.......At this point the only leak is through the piston which will control your bottoming (firmest) stage.

If you are riding outside of the designed ride height position, the intended valving for that zone will not be as it was set up for possibly netting a softer or firmer ride.
