The ICON Vehicle Dynamics 1999-2025 Ford F-250/F-350 Super Duty 4” Rear Block Kit features a square, non-tapered block design to provide easy rear lift to a Ford Super Duty pickup. These heavy-duty blocks are fabricated from CNC laser cut and brake-formed steel plate and heavy duty .250” wall square tubing to endure the stresses of heavy towing/hauling duty as well as aggressive off-road use. Their reinforced bump stop tang provides proper bump stop engagement and limits compression travel to prevent damage to the rear shocks and shock mounts at full bottom out. These blocks look as good as they perform with a semi-gloss black powder coat finish and are backed by ICON’s Limited Lifetime Warranty. These blocks are flat like the factory block and have a built in bump-stop tang.
