I have a '16 Screw 4x4 FX4. Love it!

I did a front level lift and my truck has the appearance that the front is higher than back, and I don't care for that look. I'd like it to be level, or a slight rake as I intend to tow in the future. I haven't measured the rear block, and have read that it is either 1" or 1.5". I don't want to install airbags, I would like to install new rear blocks, not an additional block. The only rear block I've been able to find is a 3" block with new u-bolts. Is this the only option, based on my restrictions......? If so, are new shocks needed? Thanks!

 

First I'd measure the distance from the center of the wheel to the fender on both front and rear, and both sides. Find the difference between the front and rear and that should tell you what you'd need as far as size to achieve the amount of level/rake you want.

I know f150lifts.com offers a 2, 2.25, or 2.5" rear block replacement. U-bolts are supplied with the package as well. I did the 2.5" front spacer and 2.25" block on mine and didn't need to replace any shocks.

Stock block on a 4x4 is 1.25".

 

Stock rear blocks on a 4 x 4 are 1 1/4 inches tall from the factory. I got the Auto Spring one and a half inch front and the 2 inch rear replacement blocks. My son did the Auto Spring 2 inch front and 3 inch rear block kit. That left us both with a one and three-quarter inch front rake. They both look great. You can buy the Auto Spring rear blocks separate.

 

Here mine with Motofab lift
2,5 in front and 1,5 rear (rear block is actually 1,5 in higher than the stock one so it's 2.75 in total)
