Fox 2.5 install questions/issues

This is a bit confusing, but sounds like you meant to say you added a spacer of some sort to the front to compensate for the lean. Was this done just for convenience? Do you know how tall that shim/spacer is?

I would highly suggest removing that spacer and adjusting preload as necessary to compensate for any lean. Thats the beauty of these high quality and expensive coilovers, they are adjustable to do this very thing. Adding that spacer, you have now changed the total extended & compressed length of that coilover. Now that shock will droop further than it should, which can cause a few different issues. The bump stop is also now too short, so the shock will likely bottom out before the bump stop engages.

 

1/4" spacer. Running 35" tires I'm measuring 41" ground to bottom of fender on both sides. I forgot to do a pre-install measurement, so not sure how much lift I'm getting.

 

If your bed is empty, get on a flat surface and measure all 4 fenders. At stock the rear is ~2.25" higher than the front. Tire pressure might screw up measuring from the ground... measure from the hub center, or top of tire.

 

41" front and 41-3/4" rear on both sides. I should have more rake than that with these +3 shackles in the rear. Sounds like I'm a little nose high.

 

+3 shackle is 1.75" lift, so you'd 41 front and 40 rear without it... ~3.25" lift in the front? Have you given it time to settle? Unless your rear tires have substantially lower pressure, that's going to make your rear measurement higher, also. Measure from the top of the tire, and see what you get.

 

I need to double check tire pressure.
My Tundra is not my daily driver but I've been trying to put some miles on it to get a feel for the shocks. What really surprised me is that the power delivery from the truck feels much greater after installing these coilovers. Cant really explain it but it "feels" stronger somehow. I wish I had done this to begin with, if anyone asks me I'm going to tell them to do it right or don't do it at all. This is the correct way to lift 3". No comparison to a spacer lift at all.

 

How close in height is acceptable one side vs the other?
I got the fox elite 2.5 all around with fox uca and eibach 1.1" springs in the rear. My pre-lift numbers vs post-lift numbers seem kinda screwed up. Not sure how/why im getting 1.5" of lift on the rear passenger side?
How close should the driver vs passenger lift be? All numbers are center hub to fender.

 

Ideally the front would be equal side to side. Unless it really bothers you visually, its not going to be noticeable. We are more concerned with what the shock lengths are at ride height to confirm the coilovers are not lifted too much, or not enough.

For example, 2022+ Tundra Fox 2.5 Coilovers FOX-883-06-218, (referencing diagram below) ideally we would like to see the shock lengths be about 20.125"

 

Is this measured with the shock uninstalled sitting on a bench or installed with the truck on/off the ground? Installed on the ground, both sides are ~20.5-20.75; a bit difficult to take an accurate measurement with the shocks installed; a bit weird that i'm measuring 3" of lift on driver side and 2.25" of lift on passenger but both shock lengths are about the same? I'll see if can take some more accurate with an extra pair of hands later today.

 

How full is your gas tank when you're taking these measurements? Any new weight in the bed of the truck?

 

Lengths would be on the truck with full weight on the suspension so 20.50" - 20.75" is not terrible. I know it can be tough to measure.
Shock measurements for those coilovers are:
Compressed: 16.310" Extended: 21.680" so you only have about 1" of down travel (at the shock) from ride height.

Measuring from center of hub to fender isn't very accurate for us. You could have a damaged body mount bushing or slightly tweaked fender. Either way, yoo are not very far off a good setup. It's up to you if you want to adjust preload to compensate for the slight lean to one side. No biggy.

 

Both pre and post lift measurements were taken with about a half tank, otherwise empty bed/truck.

 

Truck is pretty much new, I upgraded at about 300 miles. Now at 1100 miles (so 800 with the fox 2.5).
The ride seems awfully firm, seems like I can feel every single bump/crack on the road (dsc at full open all around). Would reducing preload help?
Could it be my alignment?

 

Reducing preload won't help with small bumps and cracks.

In general out of the box aftermarket shocks like these tend to ride a little firm over stock, which is why we offer custom tuning. We are usually softening up the valving to be more comfortable and compliant for street use and allow the DSC adjusters to be used for off-road driving or towing.

Did you upgrade to larger tires at the same time?

 

Very good thing to mention! Most will get LT tires with a lift and over inflate them... but LTs will ride firmer even if properly inflated.

 

We've seen a lot of people upgrade to bigger tires with load range E, which is a very stiff tire and will cause ride quality issues like described. We typically suggest load range C or D for most daily driven trucks. There are certainly pro & cons to load range choice, but that could be the culprit.

 

I did, went with C load tires for this same reason (to avoid too stiff of a ride). Have falken at4s 35x11.5x17 on some rrw's.

Sounds like I need to adjust my expectations for the time being, ill send them to you for tuning soon enough.
