Sitting in my garage is a 4"-6" Skyjacker suspension lifr for the 2009-2012 Ford F150. What I want to know is, which tire will be the best look and fit, 35x12.50R20 or 37x12.50R20? I've seen many pics with the 35s, but not too many with 37s. A little help please. Post your pics here.

 

Most Of the time I read that 37's will stress components a lot. I believe they would look the best though. Front end parts (ball joints tie rods etc) may need servicing earlier than usual though. If the lift. Is 4" do not do 37 unless you want to do a lot of trimming. 6"lift may be some minor trimming with 37 . Also there are big price differences in tires to think about. I have about 5" total lift on my 2000 expedition (3" body 2" suspension) and I'm feeling like the 35's look small now

 

just a headsup, skyjacker struts/shocks SUCK. I would replace them all with bilsteins before you put it on the truck.. With the skyjacker struts, i would be amazed if you fit the 37's without HUGE rubbing issues, they start sagging REALLY early

 

Certain lifts on the 09+ allow 37's on 6" BUT that depends on what there minimum backspacing recommendation is.

click the link in my sig, should sum up what is required if you decide on 37's over 35's. there is a HUGE cost increase other than just tire size

 

Thanks for the tips. I had Skyjacker on my 05 Ram 1500 with 37s and that thing rode like a dream.

 

Which lift did you get? I was looking at the SKYF9461KS-N. Skyjacker is the only one I'll buy since it replaces the rear leafs instead of having to use blocks. Please post pics once installed?

 

My kit has the add a leaf option, not blocks. I don't plan on doing the install for sometime, but I got the kit for $600 brand new and couldn't pass it up.

 

You don't happen to have the part number for it, do you?

 

SKY-F9461K-H
This is the kit, uses add a leaf and hydro shocks.

The last 2 characters denote either "K" for the kit, or "S" for system. The systems uses complete new leaf springs as opposed to AAL. H or N is either hydro or nitrogen shocks. At $600, I couldn't pass it up regardless of configuration.

 

Wait I'm confused. So does your kit have just one AAL or does it have the FULL leaf pack?

 

It's the kit with add a leaf and hudro shocks.

 

Oh I see. So I wonder how they get 6" of lift in the rear with just one add a leaf? They must include a block in order to get the proper height and that's what I'm trying to avoid. These pickups have bad axle wrap issues already with just the stock block; I don't want to be adding any blocks to make it even worse.
