KSP 2in Rear Lift Kit for F250 F350 Super Duty - 2in Rear Blocks

In this review the KSP 2in Rear Lift Kit for F250 F350 Super Duty is assessed for owners seeking a modest, reliable rear lift to level a truck or gain clearance for larger tires. The kit's single biggest selling point is its straightforward mechanical design: CNC machined steel lift blocks with a black powder coat and longer, 10.9 grade u-bolts that keep the factory ride quality while adding about 2in of rear lift. It is a practical choice for 2011 and newer F250 and F350 trucks that do not have overload springs.

Key Features

• Fitment: Designed for 2011+ F250 and F350 Super Duty models, providing a simple compatibility range for late-model trucks without overload springs.
• Block design: CNC machined steel with a black powder coated surface gives the blocks durability and corrosion resistance while maintaining a clean appearance.
• Support structure: Cross gusset plate locked design increases support and spreads load across a larger contact area to keep safe contact with the leaf springs.
• U-bolts: Comes with longer 10.9 grade black electrophoresis coated u-bolts that resist rust and are shaped to match original camber for easier installation and stability.
• Ride quality: The kit is engineered to maintain factory ride characteristics while providing the advertised 2in rear lift for a leveled stance.
• Installation: Can be installed with common hand tools in roughly two hours, no cutting or welding required for most compatible trucks.

Who It's For

This kit is best for F250 and F350 owners (2011 and newer) who want a modest rear lift to level the truck or run slightly larger tires without changing ride quality. It suits owners who prefer bolt-on solutions and value corrosion-resistant finish and stronger, CNC machined components.

Not recommended for trucks equipped with factory overload springs or for those with single rear wheel/no helper spring configurations unless the buyer is prepared to trim the u-bolts. If you need more than 2in of lift or a full suspension overhaul, look for a dedicated lift suspension kit instead.
