This is the weekend I am installing my MaxTrac 2/4 lowering kit on my 2011 FX2 screw. Here are the pre pics of my truck prior to installation. Here is a list of the parts and part numbers I will be using. Will post updated pics after it is all installed.
For the Front:
04-12FORD F150 3" LOWERING SPRINGS
PRODUCTSKU : 253130


For the Rear:
2009-2013FORD F150 4" REAR LOWERING KIT
PRODUCT SKU : 303440


MAXTRACSHOCK
PRODUCTSKU : 2200LL-4


Energy Suspension
Rear Bump Stop
E1299103G

 

Well it all finished. With a little headache as the instructions are not very clear and pretty basic. It took us about 5 to 6 hours to get it all installed. Here are the final pics.

 

Looks good but is the rear a little lower than the front? Looks like it lowered it over 5" in the rear instead of 4" and not quite 3" in the front. Maybe the front will settle a little. Other than that, you may need to put your factory shackle in to get the rear a little higher. Unless you like the way it looks. I would give it some time to settle. How is the ride?

 

I had the same issue on my 2008, back was an half an inch too low, had to install helper bags.
