Hey so does a leveling kit over time cause the front in to sag down? I saw this Harley davidson f150 that it was apparent he had a 3" leveling kit and got lucky enough we caught a red light next to each other and just asked him and he did have a 3". I have a 2.5" and I swear my front end is sitting lower than it was 2 years ago. Sent from my iSmarty 4
your springs/shocks could be going out. the leveling kit will not make the truck "sink" as you are thinking. weak shocks and their inability to keep the truck "up" along w/ bad coils could be a problem.
Vano I just replace my shocks and struts less than 2 months ago with Rancho RS5000s. So you think the coil overs are going? Sent from my iSmarty 4
coils are about 60-70/coil. You should always swap out your coils when you swap our your struts. most come pre-assembled so it makes you put all new in. but since you just swapped shocks, you're struts are still worn, and they do the brunt of the work in the front. think of them as your leaf pack in the rear. if you had no leafs in the back, the bed would sag and bounce like a bobble head. same for the coils up front. i would go w/ a set of code UU coils. these are the standard coil on the 06-08 Fx4 (i put a set of these on my 2wd xlt and LOVE EM).
Did you have the brush guard two years ago? The weight of that all the time alone will weaken the springs over a period of time.
The weight of that alone probably makes his truck a little lower in the front regardless of whether the springs are shot. Also, those urethane levelling disks can compress over time, if that's what you have.
