Want your truck to have that old school vibe like those from the 40's and 50's? Belltech's Rear Flip Lowering Kit will give it to you. This kit can lower your F150 by 5.5 inches in the rear by moving the rear axle from below the leaf spring to above it. It is definitely a change that people will notice. Engineered to be as tough as the truck you're installing it to, the kit is made constructed out of premium-grade steel and powder coated to defend against rust and corrosion. Grade 9 hardware accompanies the kit, making sure every part of this kit is built to last. On top of that, this kit comes with a Limited Lifetime Warranty. (See manufacturer for more info)
