ICON 1999+ Ford F-250/F-350 4in Block Kit

When you're looking to add some height to the rear of your 1999-2025 Ford F-250 or F-350 Super Duty, this 4-inch block kit from ICON Vehicle Dynamics is a solid option. What you get in this kit are two square, non-tapered steel blocks designed to easily lift the rear of your truck. These aren't just simple blocks; they're built to handle the demands of towing, hauling, and off-road adventures.

ICON fabricates these blocks from CNC laser-cut and brake-formed steel plate, using heavy-duty .250-inch wall square tubing for robust construction. A notable feature is the reinforced bump stop tang, which ensures proper engagement and helps limit compression travel. This helps prevent damage to your rear shocks and their mounts when the suspension is fully compressed. The blocks are finished with a semi-gloss black powder coat to resist corrosion, and they are designed to be a direct fit, mirroring the flat profile of the factory block.

This kit is a straightforward way to achieve a 4-inch lift in the rear of your Super Duty. ICON backs these blocks with their Limited Lifetime Warranty, giving you confidence in their durability.
