IIRC limit strap on Foxes have a couple of purposes. OEM and OME shocks are designed to limit down travel, Foxes being gen. purpose are not. Keep CVs from getting too much angle and wearing out quickly. ie protect shocks and CVs.

Edit: See Spresso answered while I was typing. I will defer to his experience and go with protect ball joint and spherical bearing rather than protect CV.

You also make a good point Cliff! The CV angle at my max droop is a very steep/acute angle.

skidoo and spress,
what size bumpstops are you running in the rear?

Just the bottom out stop on the shock. But my rear mounts are not OEM.

 

[Skidoo]

I am running the stock bumpstop in the coil spring cut down to 2" high. The stop now is more to setup up airbag for the 2" of lift. The bumpstop and airbag do provide a limit just don't know what it ends up being. BTW my shocks use the stock mounts.

So just so that I am on the same page, the fox shocks are designed to be the the limiter under compression and when extended (such as in the front) they need a limiter strap to prevent blowing out the top of the shock? Given that this is true...it seems like the OME shocks are the opposite.

Is this right?

I think it goes like this

OME/OEM are designed to limit the down travel....no limit strap needed.

FOX are NOT designed to limit down travel....so you need the limit strap.

NO SHOCK limits the up travel i.e. bumpstops are required with any shock

has anyone successfully used the 11" travel shock for the rears and a larger than 6.5" travel shock on the front? Are there any advantages to be had (compared to the 10" and 6.5")? Would this gain you any extra (if able to fit) articulation or are the 100 springs/ drive components already maxed out at the 10" and 6.5" lengths?

From the measurements I have seen in the past. 6.5" is about the limit for the front, anymore and you will seriously increase wear and tear/the possibility of joint failure.

The rear could possibly gain more down travel with an 11" shock, but since its compressed length is also longer, you will have to lower the bumpstops......reducing your up travel. With the N74L you have to lower the bumpstop .5" (i think), so the 11" fox would require more than that.

Muddy.au, can you tell us more about the Fox shocks you have? Travel lengths in particular. Does Darren have a website?

6.5" IS the max up front due to steering and CV angles that can't be improved without $$$$ costs and additional track width.

As above you want more down travel? It comes at the expense of compression travel. For slower speed running, as you originally stated, the 74L is probably your best bet.

skidoo and mlchang,

do you guys have any pics of your installs/ setups?

 

[SR.GRINGO]

What springs are being run with the Fox?

 

[SHAGGY101]

For you guys who are using the FJC rear shocks, do you know if you are using all of the shock's up-travel before the axle bottoms out?

 

[Skidoo]

I am running OME 866 rears w/ Airlift bags and OME T-bars, Spresso has different rears, check his featured build thread.

I didn't respond as the OP seemed to be pointed at just the FJC Fox Shock guys. But for the record I'm running OME 864 springs (with Airlift bags that get aired up when I'm pulling my KK trailer); but as you know the spring type/model is strictly based upon load carrying capability and/or lift height considerations that are typically unique to each person's rig set-up.

 

[SHAGGY101]

I was not specifically interested in just the FJC shocks but the typical 10" shocks as well. I am just trying to decide what shock will fit my rig the best. When did my springs, I measured the rear travel capabilities without the shocks installed. I measured 16" fully compressed and 26" at full extension. These numbers point me in the direction of the Fox 10" travel shock. This shock would allow me to use the full extension of the shock with minimal bumps stop extension. These measurements, however, were taken with respects to straight up and down travel. The axle was not flexed out. I was curious to know that if the full travel of the FJC shock gets used or is there and inch or so that is not used. This would also apply to the typical OME shocks as well,not the N74Ls.

I hope all of this stuff makes sense. You might have to read it a few times...

Thanks for all of the replies/ help

 

[Skidoo]

How are you measureing full extension? Just shocks off? sway bar disconnected? Some have extended sway bar links by 50mm which may or may not change that.
BTW: Don't have any measurements on my FJC foxes.

 

[hoser]

As skidoo said, an un-extended links will limit extension as well as frame to axle brake line(s).

 

[spressomon]

I didn't check if the FJC Fox 2.0" Remote/.625" shaft is available in the 11" travel or not. Assuming they are available in the FJC/post style upper mount you'd need to bump stop the compression side to account for the 1" longer compressed shock length and then secure the coil springs so they don't dislodge/unseat when completely unweighted.

Otherwise the 10" will work just fine. Assuming you have or know someone that has the ability to tune shocks you will not regret the decision on the Fox investment. If you have basic mechanical skills its an easy process to change valving; you'll just need to invest in a Fox shim kit and some Fox shock oil. And, as you probably know, if you tune the shocks for your rig today and then later add a significant amount of weight (in the form of bumpers, winch, drawers, cargo, belly pans, etc.) you can change the tune/valving to suit rather than compromising and/or replacing the entire shocks.
