EVIL ENERGY Wheel Spacers Front 3-Inch Rear 2-Inch for 2004-2023 F150 2WD/4WD – Forged Strut Spacers Suspension Upgrade

Q: Do I remove the factory rear block on my F-150 before adding the 2 inch lift block?

A: Some 4x4 F-150s come with a factory rear block from the plant. Follow the included instructions on whether to replace it or keep it. Do not stack two aftermarket blocks on top of each other; that can let the axle slip under braking or towing.

Q: How do I choose the right rear lift blocks for my F-150?

A: First measure the current front-to-rear fender height difference, then pick the block height that matches the front lift. For a 3 inch front lift, a 2 inch rear block keeps a slight rake so the rear does not sag when towing. Blocks larger than 3 inches usually need longer shocks and brake lines.

Q: Are 4 inch rear lift blocks a better choice than 2 inch blocks on an F-150?

A: A 4 inch block makes the leaf springs much more prone to axle wrap under hard acceleration and puts more stress on the driveshaft angle. For a daily driver or a towing truck, a 2 inch block is the more balanced choice.

Q: Does the F-150 3/2 lift kit fit both the 5.5 ft and 6.5 ft bed?

A: Yes. Bed length does not affect fitment. The strut spacers and rear blocks fit both 2WD and 4WD 2004-2023 F-150s regardless of cab or bed size.

Q: What tire size fits an F-150 with 3 inch front and 2 inch rear lift?

A: Many owners run 33 inch class tires such as 285/70R17 or 275/70R18 after this lift. Wider tires may need wheel spacers to keep them from rubbing the upper control arm.

Q: How long does it take to install rear lift blocks on an F-150?

A: Most DIY installs take about 1-2 hours for the rear blocks and front strut spacers combined, depending on rust and access. Work one side of the axle at a time so it stays centered.

Q: Does the F-150 need a longer brake line after a 2 inch rear block?

A: At 2 inches, the factory brake line usually has enough slack. Check it at full droop after installation; if it is tight, an extended brake line bracket fixes it.

Q: Will this lift kit affect the F-150's EcoBoost turbo heat shields or exhaust?

A: The kit does not touch the exhaust or engine components. The exhaust hangers stay in place because the frame does not move relative to the exhaust.

Q: Do I need to recheck the U-bolts after installing F-150 lift blocks?

A: Yes. Recheck U-bolt torque after the first 50-100 miles, because the spring pack and blocks settle slightly. Loose U-bolts are the most common cause of block shifting.

Q: Is an alignment required after installing the F-150 lift kit?

A: Yes. The front strut spacers change camber and toe, so align the front end right after installation to prevent uneven tire wear.
