Fox Life!!! Anything Related to Fox Suspension

Ridge Grapplers in SL. To clarify I’m not stating my current suspension feels that way, I’m stock still but don’t want to get the fox 2.0 if they have that much road feel.

 

I may be oversimplifying things, but can determining preload using the above method be a rough gauge for amount of lift achieved?

 

Probably, but its easier to measure lift height a few other ways as long as you know what the stock measurement is. We would not measure preload to see how tall the vehicle is, we would measure shocks lengths at ride height using this diagram.

We steer clear of trying to hit a specific lift heights. For us, shock position (at ride height) compared to its overall travel is more important. You may be stoked to hit that target of 3" lift, but now the shock may be almost fully drooped out and ride very poorly.

 

Right on. I have a new to me set of Fox 2.5 coilovers that I was hoping to forecast any lift I might incur by measuring preload if that was remotely feasible. Understanding that it would not be exact.

 

Totally get that. Unfortunately its not very simple otherwise we would offer it to customers since we remove the springs when we revalve the shocks.

 

Word. I’m actually not looking for max lift. Much more so the opposite. I’m actually considering backing off some of the existing preload, possibly even dropping down to a 13x600 spring vs the 14x650 currently installed.

My goal isn’t necessarily lift, but rather improved damping and control with some recently added weight up front.

 

Changing the spring will not improve damping and control, thats what the valving inside the shocks do. We always start with getting the correct spring rate to hold up the weight of the truck, then proper valving to control all the weight. We also factor in how the vehicle is being used most.

Do you have Fox 2.5 remote reservoir coilovers? Do they have DSC?
How much added weight do you have up front over stock?

 

Remote resi yes, DSC no. They are the

$1,611 880-02-418 Coilover and Upper Control Arm Kit

880-02-418.

My bumper and winch combo is right under 150#, steel IFS/mid skid and steel sliders. Out back my only added weight is a fiberglass shell on a 3 leaf AAL with stock OL leaf.

 

With only 150lb up front, a 14x600 would work. If you are trying to get better ride quality out of the shocks, it may be worth exploring a revalve. Only downfall would be needing to send those into us.

 

Haaving you guys valve them, or starting with you to begin with, would be ideal. That may be cost prohibitive at this point. The coilovers were purchased locally at a reasonable price.

It’s borderline frustrating to hear you suggest 14x600. That’s the outlier spring I don’t have currently. The 14x650 are installed, and I have 13x600 on hand but not installed

But thank you for the feedback nonetheless.

 

Your 13x600s should be fine, Accutune set mine up with 12x600s and I've beating on those for 40,000 miles now, they're do to be sent in

 

Right on. I tend to be super indecisive.

As of yesterday evening I’d all but decided to just run them with the 14x650 since they’re already set up that way. Now, who knows haha. It’ll just be a game time decision.

 

12x600s?

 

Thats what I thought they were but I guess I could be wrong, I know when I sent them back I'd like to change to a longer spring just not have so many threads showing, I could easily run a 2" longer spring

 

I'm going to guess it was either a 13" or 14" x 600lb spring. 12" is too short

 

If I swap my coils to the lighter 13x600 I’ll likely be looking to sell the Eibach 14x650 if you’re interested.

 

Appreciate the thought, but I agree with accutune on the 600's. I've had to add a little preload a few times due to settling but I wouldn't want to go with any stiffer spring than necessary.

 

Right on.

I keep going back and forth on whether I’ll leave the 14x650s that are already installed on and back way off on preload. Or if I’ll swap to the 13x600.

I’d rather err on the side of softer ride vs firm so my gut says the 600 may be the safer option to start with. Would really like to avoid multiple install/uninstalls with alignments.

 

Unless you're changing ride height at an extreme level your alignment will not be affected by a spring change, it's just the physical work is a pain, unless you enjoy doing it!

 

Not to beat a dead horse, but does anyone know the amount of threads (measurement is great) of preload that come preset from Fox on their 2.5 Race series with remote resi? Preferably with a 13” x 600lbs spring or a 14”?

I’m not trying to achieve any specific lift height or ride characteristic based on others applications. I purchased mine used, so I’m simply trying to get them back to, or compare how they’re set now, to how Fox would have set them when new.
