Spring were too long to fit in with the stock springs.

You must cut almost 2" off of the spring to enable fitment on the Raptor. Although they show it fitting, it does not & should not be installed unless you are willing to make these modifications

Great Product!!!

I have an 09 Ford f150 and as many of you know it looks like they lowered them from the previous year, probably an attempt to cut wind resistance for better fuel economy. I put a 2.5 inch lift all the way around and found the lift is fantastic! The lift actually improved handling and feel. The ride stayed the same and is a nice improvement to the overall look of the truck.

I have a 2011 f150 fx4 with a 6" rough country lift. I am wanting to push it to a 8" lift by using the bilstien 5100 adjustable shocks in the front and these pro comp leaf springs in the back. Would the leaf springs work and raise my truck to 8"?

Asked by Ryan from Waco,Texas on

Ryan- Thanks for your question. The Pro Comp Suspension Rear Add-A-Leaf Kit will work with the factory leaf pack only. If the rough country lift kit you have is lift blocks only, you will gain 1.5 to 2 inches. You will probably have drive line issues at this lift height.

I'm looking for something to stiffen up the rear since I got my lift. It's got a little bouncy and I was wondering if this would work or fit. I have a 2011 f150 with a 6 inch procomp lift with 35x12.5r18

Nate- Thank you for your question. The Pro Comp Suspension Rear Add-A-Leaf Kit will make the rear a little stiffer. You might also try the MX-6 reseviour shock. This shock is adjustable, that way you can tune your ride to your taste.
