Fox 2.5 DSC install questions/install - Toyota 4Runner Forum

Installing Fox 2.5 CO with 600 springs. How much thread should be exposed in order to get ~3" lift? Out of the box is showing 2-3 threads, maybe 1/4".
Thanks!

The easiest way to adjust them is on the vehicle right? In order to hold them secure enough to thread the collars.

I've heard mixed reviews on this. Certainly the older version with 2 rings it's very difficult. Even with the single ring version it sounds like it's hit an miss.
I don't mind making small adjustments on the vehicle but I'd prefer to not have to spin the collar down 3-4".

They aren't too bad to adjust installed with that corner jacked up. Only loosen the pinch bolt enough to spin the collar, too loose and it'll jump threads. LUBE it up good. The spanner tools that come with coilovers are junk, get a big punch that fits the holes (3/8" I think? don't quote me there). Mine have ~1-1/4" thread showing for 3" lift v8 with dual battery and twin compressor up front, no bumpers or winch.

Do you know what springs you have? It looks like mine came with 14" 600 lb springs. I'm surprised you got 3" lift with such little thread showing, that's encouraging. Thanks for the feedback

I could check the part numbers when I get home but I didn't specify spring when I ordered so I assume they are the standard 14" 600#.

Nice shocks… looking forward to hearing about them.

Pretty sure that's the hardest possible way to adjust them. If you know what they need to be adjusted to it's about 1000x easier to put them on a bench and clamp the top hat or use a crow bar through the bolts and turn it. Can you adjust them on the truck? Sure, but it sucks dick with everything in the way. If they're out already do them off the truck.

Yeah I agree. Fox is claiming they're preset for 3" lift, I don't see how that's possible with so little thread showing. These are supposed to be for 0-3" lift so there's no way to back them off to 0"?
I just want to get it close so I'm not turning it so many times on the vehicle.

My girlfriend has the normal 2.5" Fox coilovers, I would assume the spring is the same but I can't find any markings saying the rate that are (easily) visible. She's at 22" hub to fender and 2.75" of thread showing. She has an aluminum plate bumper and that's it.

Counted mine for ya, I have 12-13 threads showing above the collar. There are older versions with shorter springs which might be where people are getting the 2.75" thread showing. I know looking at another guy's build before I bought mine he had about 3" of thread showing.

Thanks for checking. I'll count 12-13 for a starting point and set the driver side a little higher. Hoping it's not too difficult to adjust on the vehicle.
Excited to try this set up as I was never too fond of the 5100/Tacoma spring combo. Always felt bumpy and stiff at the top but would blow through the travel on big bumps.

Please keep us updated as I'm interested to know how much lift you get from 12 threads showing. Thanks . Do you have any added weight? What did you use in the rear?

That was my exact impression of 5100s as well. No complaints with the Fox with DSC, high speed compression always set at highest setting, low speed compression all the way low for slow offroad crawling, all the way high for "aggressive street driving" but usually a couple clicks back off of highest setting for daily driving or long road trip comfort.
