Belltech Sport Trucks Lowering Kit for the 09-13 Ford F150 Ext & Quad Cab 2WD Short Bed is designed specifically for you to be able to raise, as well as lower your truck. This kit is adjustable in ®" increments, so the you will have the option to raise the truck up to 1" higher than stock, and lowering it all the way down by 3" in the front. In the rear of the truck, up to a 5.5" drop can be expected.
We had the stock suspension swapped out for a fully adjustable Belltech setup that allows the truck to be raised or lowered per the owner's tastes.
Take a look at the MPT Ecoboost for a reference to see the real difference you will see when lowering the truck from stock. (NOTE: Our truck in the picutres is the 2WD model)
