Our 2012 5.0L Project truck needed to go a bit higher in the rear, which meant we needed a rear block kit of some sort. Our friends over at ReadyLift were more than happy to help us out and sent over one of their excellent 2004 to 2014 F150 4WD 3" Rear Lift Blocks to help us out. This pair of 3" blocks add about 1.5" of ride height to the rear of a given F150, and they were perfect for giving our truck a leveled look in conjunction with our ICON Front Coilovers which add up to 3" of front ride height. In essence, we threw a 3" lift kit onto our truck without needing to do anything crazy like replacing spindles, driveshafts drops, or anything else that's common with taller and "more complete" lift kits. Anywhere, here's our very own install guide for ReadyLift's rear blocks. Enjoy!
The first step of our pretty straightforward rear block install was to take our 2012 F150 project truck over to Extreme Performance out in Goodyear, Arizona, where Kris and JD were waiting to help us out and to once again show off all their tattoos. Not that there's anything wrong with that. We rolled in, and the guys threw the truck on their lift, got the stock tires off and got to work.
With the truck in the air, JD grabbed a few adjustable axle stands to push the axle against the springs and relieve their tension so he could start loosening the factory U-bolts without them or the axle flying in his face. For the DIY in the garage sort of install, a good jack and jack stands should be all you need for this part of the install.
Once the stands were secure and adjusted to the correct height, JD loosened the nuts holding each of the u-bolts to their axle bracket. Expect a ton of dust to fall out of the brackets as you pull them away. There's only 46,000K miles on our project truck, and there was dust pouring out of these things.
After all the nuts are off the u-bolts, pop the brake line clips off each of the u-bolts, remove each bracket, and take the u-bolts off your truck.
Now that the u-bolts are off, JD lowered the axle a few inches with the stands and pulled the factory block out without too much trouble.
Installing the ReadyLift 3" blocks wasn't quite as simple as popping the factory ones off. First JD had to hit the leaf spring block "nubs" with some penetrating oil to get some of the corrosion off. Then he had to bring over another axle stand and place it under the driveshaft input into the differential to help rotate the axle into proper alignment with the leaf springs. While not overly difficult, the process was a bit tricky.
After you've wrestled ReadyLift's blocks into place, JD raised the axle using the stands and settled everything into place. With everything properly seated, he grabbed ReadyLift's larger u-bolts and draped them over the leaf springs and axle.
He then reconnected the plastic clips and grabbed the u-bolt nuts and brackets and fit the brackets back on just finger tight to make sure everything was looking just dandy.
With everything looking good, JD grabbed his impact and tightened all the u-bolt nuts back to their proper torque. Install complete. The end result was a perfect amount of rear lift to go along with the extra 3" lift up front courtesy of a pair of ICON Front Adjustable Coilovers.
Overall, the install of ReadyLift's 3" blocks was surprisingly easy. Even though we had the benefit of a lift and a full shop at our disposal, getting a set of these bad boys on with a few jacks and jack stands is entirely doable for the DIY-minded individual in the garage or out in the driveway.
