KSP 2in Lift Block for F150 2004-2020 - Rear Leveling Lift Kit

In this review the KSP 2in Lift Block is evaluated as a simple rear leveling solution for 2004-2020 F150 models. The bottom line: this is for owners who want a modest, reliable lift or to restore rear height after added weight, and it stands out for its straightforward fit and sturdy construction. Installation is basic for anyone comfortable with leaf spring work, and the kit's powder coat and cross gusset plate give confidence in long term durability.

Key Features

• Fitment: Designed to fit F150 models from 2004 to 2020 in both 2WD and 4WD applications with clear notes on stock block height differences.
• Lift Height: Provides a full 2in rear lift for 2WD trucks and an additional 0.5in on 09-20 4WD trucks where a 1.5in stock block exists.
• Durable Finish: Black powder coat protects the block surface against rust and keeps the underbody appearance tidy over time.
• Reinforced Design: Cross gusset plate locked construction increases support and spreads load across the block for better stress distribution.
• Hardware Quality: Supplied extra long U-bolts are grade 10.9 with 9/16 thread pitch, giving stronger clamping than many stock bolts and room for trimming if needed.
• Support: KSP backs the part with a 30-day refund window and 12-month free replacement parts service for peace of mind.

Who It's For

This kit is best for F150 owners who want a simple, cost-effective way to level the rear of their truck or regain ride height after adding weight to the bed. It suits do-it-yourselfers and home mechanics who have basic tools and experience with leaf spring and axle work.

It is not aimed at those seeking multi-inch performance lifts, full suspension overhauls, or adjustable coil/air systems; owners who need more than a modest rear lift or who prefer bolt-on adjustability should consider more comprehensive suspension kits instead.

Pros & Cons

Pros

• Easy to install with common tools and a design that fits the leaf spring closely for good contact.
• Solid construction with cross gusset plate and black powder coat that improve longevity and looks.
• Includes longer 10.9 grade U-bolts that are stronger than many stock bolts and can be trimmed to fit.
• Clear vehicle fit notes reduce the risk of ordering the wrong part for 4WD vs 2WD variants.

Cons

• U-bolts are longer than stock for some setups, and trimming may be required which adds one extra step for some installers.
• Will not provide a lift on 04-08 4WD trucks that already have a 2in stock block.
