KSP 3ft Rear Lift Block Kit for F150 2004-2020 - 3in Rear Leveling

In this review the KSP 3' Rear Lift Block Kit is judged as a focused, practical solution for F150 owners who want a modest rear lift and a cleaner stance. The kit is best for 2004-2020 F150 models and its single biggest selling point is compatibility: it provides a true 3in rear lift on 2WD trucks and the correct additional lift for 4WD variants depending on their factory block. Installation is straightforward for a competent home mechanic, and the kit's construction aims to resist corrosion while offering stronger support than basic blocks.

Key Features

• Fitment: Designed for 2004-2020 F150 2WD and 4WD, it provides the advertised rear lift relative to factory block height.
• Lift amounts: Provides 3in of lift on 2WD F150s and the appropriate extra 1in or 1.5in on 4WD models depending on model year.
• Black powder coat: The powder coated surface improves rust resistance and keeps the blocks looking clean over time.
• Cross gusset plate: The cross style gusset plate locked design gives a firmer, more uniform support surface than plain blocks.
• High grade u-bolts: Supplied 10.9 grade u-bolts with 9/16 thread pitch are longer than stock for tuner fitment and can be trimmed if too long.
• Support policy: Backed by a 30-day refund and 12-month free replacement parts service for buyer reassurance.

Who It's For

This kit is ideal for F150 owners who want a rear lift without replacing springs or complex suspension parts, especially 2WD owners seeking a full 3in raise to match a front level or to increase ground clearance. It also suits 4WD owners who need the correct incremental lift to compensate for factory block size on specific model years.

People who want a complete suspension rebuild, air ride, or who need exact ride height tuning beyond the fixed block sizes should look elsewhere. Also, anyone uncomfortable cutting u-bolts or performing axle work without help should consult a shop.

Pros & Cons

Pros

• Easy to install with common tools, making it accessible for DIY owners.
• Robust cross gusset design and powder coat improve durability and appearance.
• Supplied 10.9 grade u-bolts provide strength and flexibility for different setups.
• Clear fitment notes for different model years reduce guesswork before purchase.

Cons

• U-bolt length receives mixed feedback; some buyers may need to cut them to fit precisely.
• As a block lift, it fixes ride height but does not address changes in ride quality or spring rate.

Frequently Asked Questions

Will this raise my 2007 F150 rear by 3in?

Are the u-bolts ready to install or do I need special tools?
Answer. The kit includes 10.9 grade u-bolts that are longer than stock and can be installed with common tools; they can be cut if they are too long for your setup.
