I'm starting to suspect the rear leaf springs may be weak/sagging.
Before I lower the Fox coil overs I'd like to see if anyone has thoughts or measurements to clarify.

Top of 20" OEM rim to bottom of wheel well (with stock flares).
My tape measure reads:
Front: 13-11/16"
Rear: 13-1/6"
Fox coil overs and Fox rears the front is 5/8"higher with 2-3/16" shock from bottom of collar to bottom of threads.

Pre-Fox was OE front and Bilstein 5100 rear. I had 1-3/4" rake (don't have actual individual measurements).

2017 Lariat 4WD 2.7 shortbed 20" rims, 100,000 miles, no HDPP/no Max Tow/no trailer brake, but has towing package. Rear springs are lightest "A" (4 strengths A, B, C, D).

 

For a precise measurement, measure from the center of the wheel to the wheel well lip. Measurements from the edge of the wheel would be all over the place as there are many different sized wheels.

I’ll take a measurement of mine shortly.

measurements:

my truck is stock.

22 1/2” front
25 1/4” rear

Measuring from dead center of wheel to wheel well.

 

It seems to be about 23-3/4" rear and 24-1/4" front.

I've been looking and seems people trucks are in the 24"-25" range for the rear?

So the rear seems a bit low? I have a rolling tonneau with has some weight, maybe 100 lbs and lightest leaf spring rate (#A).
