Rear Suspension - Factory Sag?

[Texcellent]

Curious, unloaded bed on a full tank of gas (36 gal) how much rear suspension sag do you get from driver/passenger side?

Example (taken from ground to fender)
DR - 40-7/8”
PR - 41-1/2”

What yall got?

Mine has always been different but 5/8” seems a bit extreme..

Gas tank creates the sag.

Agreed, but doesn’t that seem like a lot?
Maybe it’s not and everyone has similar results. Just trying to get confirmation I’m not crazy

Are you always driving in a straight line for at least a couple of truck-lengths before stopping to measure?

Can’t say that I have to be honest. I’ll check that and report back.

Does Ford not use different spring rates left to right? My previous trucks all had a stiffer spring in the left front to compensate for fuel and driver.

How much difference do you have with a near empty tank?

Put the standard tools and supplies you carry on the passenger side to compensate.

Interesting, when I look at the many-pages detailed specifications (aka 'factory build sheet') for my 2022, here's what I find, which IMO indicate the same front spring rates L&R:

TABB2		JL34-5310-S* L/F COIL SPRING
TADB2		JL34-5310-S* R/F COIL

I do not find any line-item referencing the individual rear leaf springs, only these entries possibly related to the rear suspension

Springs are same right to left. Also same for 26& 36 gallon tanks.
just changed out to icon springs and am quite happy. Took out the factory block as well. Used the icon kit as well. Went from 7.25 inches to 10 inches from top of tire to bottom of rear fender.put the rake back in after the fix 2.5 struts up front. It will hopefully settle just a bit.

I was level with just my usual work stuff in the bed. But the new springs keep me off the bump stops.
