I installed a 3.25 RC lift kit a couple years ago & noticing quite a bit of sag. I realized I purchased the RC kit for the 4 cylinder but I have a 6 cylinder.(4 cylinder was on sale at the time and being new to wrenching I didn't think it would matter since it was suspension lol) It appears that the only difference between the kits are different coils.

I don't care too much about the height, besides my tires fitting. I was thinking about going with a bit lower coil but need to fit my 33x10R15 KO2 tires.

Any assistance on best path forward would be appreciated. I mainly drive on road so looking for best ride commuting around town.



Thanks!

You’re going to need the height for 33” tires. If you drop coil size them maybe body lift or just buy front coils. Just throwing out options that you probably already know.

Since the shocks are for the 3.25 lift kit does that change what size coils I could get?

Possibly. What's the compressed and extended length of the shock?

Spring reference...

Rough estimate but both seem to be sitting around 2". I haven't done the measurement before so not sure if I'm doing it correctly.
 
Measure the springs by themselves at ride height. The RC 3.25" lift has 2.5" lift coils with 3/4" spacers on top. The coils should measure 14.5" front and 10.5" rear. Anything less is sag.
p.s. I ran that kit with a BL and 35s on my old white 03'.
