I leveled the front of my truck (2005 F150 STX 2wd) with a 2.5 poly Tuff country leveling kit. Now the back end sags really bad when I pull my trailer. Are there any add a leaf's that only raise the back end by 1" or 1.5"? And would it be worth it to replace my stock shocks with Rancho's or higher end quality shocks? And does anyone know if I can fit 35" MT's or should I stick with buying 33" MT's. Im not sure if 35's would rub especially because I pull a heavy trailer a lot. Any Input in much appreciated! Thanks guys

 

Don't have much to add on the add-a-leaf except for when I was thinking about this option, I got quite a bit of feedback that it will ruin the ride when not loaded. 'Tank' was the reference mostly used

I jumped on here to say this...since you mentioned you pull a heavy trailer and that you're looking for taller tires, you MUST budget and plan for gears!!!! Even if you only go 33's, it will make a difference. If you go 35's, new gears are now a requirement. Based on my experiences, I'd go 4.10 with 33's, and 4.30's with 35's. If you have 3.55's now instead of the 3.73 option, you're already behind the power curve.

 

Call Kevin at AutoSpring Corp. and tell him what you want to do. They took some of the curve out of my AAL as I did not want anymore than 1.5" of lift from it. I would imagine that they could do it for you also.

 

Thanx guys. Hey Ameration how is the stiffness of your ride now that you added the leaf in the back. Is it really stiff? and also do your 35's rub at all/ or do they get close to rubbing anything?

 

Not too much more stiff than stock, but it is noticable.

The 35's do not rub but they are close at certain points in the front when turning.
