High-Quality and Tough Pro Comp 6" Lift Kit

A 2004 to 2008 F150 with a 6" suspension lift is probably one of our favorite things in the world, and when you want to shoot your truck up into the air, you should grab a lift kit from the masters over at Pro Comp. This complete 6" lift kit allows you to fit on up to 35" x 12.50" onto your F150 without any cutting, trimming, or other modifications. The lift kit combines new front and rear crossmembers with larger rear blocks, taller spindles, and some of Pro Comp's ES9000 performance shocks that all work together to give your tough F150 up to 6" of total lift and a nice improvement in suspension performance all in one high-quality kit with perfect fitment onto your truck. The Pro Comp F150 6" lift kit is an excellent choice for an aggressive street truck that sees plenty of weekend trail riding.

Features Front Crossmembers, Rear Blocks with New Shocks, and All Required Hardware Included

The Pro Comp 6" ES9000 F150 lift kit comes with everything you need to give your truck a tough new ride height and the ability to squeeze on extremely large wheel and tire options. The kit is built around heavy duty crossmembers that come with braces that allow them to be used in even the most extreme applications. The rear lift blocks easily install between your truck's leaf springs and axle and come with high-quality U-bolts to hold them perfectly in place. The kit's ES9000 shocks are a specially-designed white-body shock that deliver good off-road performance while still giving your truck a smooth, clean ride on the street or the highway. Each ES9000 has 10-Stage, velocity sensitive valving and a 1-3/8" nylon-banded piston that allows them to hold up to basic off-road applications without failure. Rounding out Pro Comp's 6" lift kit is all the other hardware you need to throw this lift on your truck while maintaining all your other functions. The kit comes with brake line extension brackets, a centerlink steering drop, sway bar drop kit, and a differential drop system. Pro Comp's 6" lift kit comes with all its necessary installation hardware and detailed instructions.

With this kit do u need to change any other parts like drive shafts fronts CV axles or anything else to make this kit work ?. and will it work with a rancho quick lift leveling shocks already on the front of the truck?

Asked by: dan - 11/14/2014

You won't require new driveshafts, CVs, LCAs, or anything else (unless those components are worn down to the nub and require replacing). The Pro Comp is compatible with all of your factory hardware. The kit will technically work with the QuickLifts, however, we really don't recommend using them unless you absolutely have to. The QuickLifts aren't really designed for use with a lift and their ride quality will suffer, not to mention that their increased front ride height over the stock struts will probably cause your truck to ride nose-high with rear rake.

I recently bought an 04 fx4 that already had rancho quick lift struts in the front and a an add a leaf in the back and it currently sits with a front ward rake. if I were to add this system with the current quick lifts or say a pro comp adjustable strut torqued to max that should make the truck sit level right?

Asked by: Alejandro - 5/14/2015

You'd likely still have some amount of rake, even if you do add this kit. Your best bet would be to call us directly at 1-877-578-2433 so we can get more specific about how much rake you have so we can find a solution.

In the pictures it shows the CV angles are pretty much straight. With that being said, would it be feasible to run a Bilstein 5100 leveled strut cranked up 2 inches? I know you aren't technically supposed to do that because excessive wear. But if the CV's are straight, then wouldn't that just be a "leveled" truck with the lift. It'll still be in spec right?

Asked by: Bryan - 7/28/2018

It is possible. However, you do need to be careful to watch your brake lines, and your main driveshaft so ensure it's not slipping out of its yoke too far. You'll also have a noticeable amount of rear rake at 8" of front lift, which is also something to keep in mind.
