Fitment:

2009-2014 F150 4WD
This Kit Will NOT Fit 2WD Models
Should NOT Be Installed On 2009-2013 Raptor Edition Models

2014 F150 Fitment: this kit will not have proper, bolt-on fitment to a 2014 F150 due to changes Ford made to the 2014's front suspension. Call 623-434-5277 for more information.

Wheel fitment and kit notes: This kit requires cutting your truck's subframe for proper fitment and will not fit factory 18" or 17" wheels. This kit REQUIRES at least an 18x9" wheel with a maximum of 4" to 5" of backspace. All 18x9" wheels should be test-fit before installation, due to design variations that can cause fitment issues. For all other fitment questions, please contact Stage 3 directly at 623-434-5277.

Installation: Vehicle will require alignment after kit is installed, also it may require fender modifications for maximum tire size fitment.

I have a 6" pro comp lift on my 2013 f 150. the top bolt on the bracket bolted to the top of the front diff has fallen out. what size bolt would that be?

Asked by: B Deveer f150 2013 - 1/28/2014

I believe it's a Grade 8 9/16" x 4" bolt, but Pro Comp's kit also reuses some of the OE bolts. Your best bet is to give us a call at 1-877-578-2433 so we can figure out specifically which bolt you need.

The mx coil-over/ mx6 shocks upgrade is + $800 do you sell these separate from the lift kit for the same pice?

Asked by: Russellthecrow - 10/11/2014

The price should be similar, though it will depend on how Pro Comp prices them out in the end. But yes, we can get the coilovers as a separate item from the kit. You'll just have to give us a call directly at 1-877-578-2433.

Im looking at lifting my truck in the near future but am worried about rubbing. I'm looking at getting 22x14 American Force Fallout FP6 wheels I'm looking at pairing them with 35x12.50 Toyo Open Country MTs. How much rubbing will I experience on a 2010 f150 with this kit? Wheels have a 5 inch back spacing and a -73 mm offset.

Asked by: Chip - 7/30/2015

As long as you stick with 35x12.50" tires, you should be okay or only get a slight amount of rub on your front lower valance, which can be trimmed. That being said, going with that big of a wheel can cause some issues, so your best bet would be to call us directly at 1-877-578-2433.

I have the 6" pro comp lift on my 2010 f150 what would I have to get to make it a little bigger ?

Asked by: Michael - 12/4/2014

Since the kit uses a front lift spacer, all you'd need to do up there is grab a set of adjustable coilovers or lifted struts to get some extra front height. For the rear, you need either a larger block or a Pro Comp Add-a-Leaf Kit, along with longer rear shocks to handle the extra height. We generally recommend the BDS FOX 2.0 Rear Shocks.

Can this kit be combined with bilstein 5100s to achieve about 7inches of lift? I have 22x12 -44 wheels i want to run 35 in tires on

Asked by: Erik - 9/15/2016

You technically could, though you have to keep in mind that the Bilstein 5100 struts have perch settings for stock ride height, +.75", +1.50", and +2.25" of ride height. Frankly, we would only recommend using +.75" ride height to start out to gauge where your UCA, CV, tie rod, and LCA angles are going to be. You could probably get that particular wheel and tire combination on the truck without any additional lift, depending on the width of the 35" tires that you have in mind, though your best bet would be to give us a call directly at 1-877-578-2433 so we can get more specific with what you're going for.
