Does anyone have the " MAGIC NUMBER " for the valving for these shocks

Defender 110 , OME 764 F / 755 R, lowered Towers.

I would like to put either Blings 7100 Remote Reservoir
( thinking of 710012SB )

or

Fox 2.0 12 Travel Remote Reservoir

Thanks

for the blistien 360/80...let's you use the nitrogen pressure to soften or stiffen them to suit your ride...

90/100 or 85/95 for the fox 2.0's

i'd probably go goofy custom on your 110, that diesel is heavy.
maybe 95/105 in the front and 90/100 in the rear... unless you run with a pile-o-crap in the rear, then maybe same/same

Well will have a PPCage installed plus peli fuul of crap, so I think your idea is not that goofy, and always like same/same ( less spare )

Thanks

based on what youve written:
764 front @ 220 spring rate with your diesel youre probably just at a 2" lift with your tdi and bumper.
755 rear @ 280 spring rate would give you a solid 2" lift with a fair amount of load.

something to consider, these are pretty light spring rates for a diesel and a rig youre gonna pile with crap...any heavily valved shock is gonna work hard for it's money to make you happy. just food for thought.

your retained or un?
swaybars or no?

also, you might want check your available shock length space on the front of your 110, a 12" fox is an awful lot of shock length for a 2" lift, and that's with out lowering your towers.

It is currently running
764/755 with 14" blings 7100 non remote and the original towers, Retainned
Sway in back, but disconnects when off road.

Cones will be placed as well.

the lift is a tad over 2" now. I have equipe bumper and Epi9.0S winch.

I have loaded with a bucnh of crap and still stayed straight, when I hooked the m416 the ass stayed straight if the crap was on the trailer

Thanks

gus are you sure they are 7100's? sure they are 14"? You will absolutely not get more than 8 or 9 inches of travel out of the front suspension even with a longer shock. if you lower the front mounts you will bottom out the shock on compression and break them. Even if you were able to lower the front mounts, the radius arm bushing at the frame is going to be the limiter of travel, not the shock itself. I spent hours laying in the mud under my truck "researching" this very issue. For stock setup if you want adjustable valving I think the best thing is the 8.5 inch fox like I have. Near as I can tell that is the longest shock that will fit the stock mounts.

and, guys...lift does not affect shock length space. there is plenty of room to completely compress the axle right to the bumpstops even with a 2" or 3" lift.

I seem to recall hearing that Keith @ Rovertracks is knowledgable regarding Fox valving. FYI Fox does sell a shock that is designed to fit the stock 110 setup, which is what you have.

yu got it.

with the radius arms setup and factory upper shock mounts front and back. You might get a bit more droop out of the radius arm if you use a cranked model such as Rovertym makes. The dog-leg in the arm allows the bushing to be more relaxed at regular ride height thus allowing a bit more droop before the bushing binds.

The only way to get 12" of useable travel in the front is to modify the radius arms or go with a 3 link setup. (or 4 link if that becomes available). Cator corrected radius arms don't help.

Anyway, the compressed distance between the upper shock mount and the lower shock mount is fixed. The only thing you can do to prevent destruction of a shock that is too long is to fit longer bumpstops.

A lowered upper shock mount will get you some downward travel that is normally restricted by stock length shocks. But you need to check the compressed distance to avoid damage.

The fox shocks I have are about 2" longer than the stock shock. If I fit lowered mounts they would get broken.

Dave,

When you say " stock set up if you want adjustable valving "
what do you mean exactly ?
Not sure I follow, if you mean radius arms, towers,
Help man and speak english would you LOL
