The ICON Vehicle Dynamics U-Bolt Plate Kit is an essential component to install ICON 5” lift rear leaf springs onto 2011-2025 Ford F-250 and F-350 Super Duty trucks. These heavy-duty fabricated, CNC laser cut steel plates replace the OE U-Bolt plates and allow ICON U-Bolts to secure the new leaf springs to the rear axle. The plates look as good as they function with a dual stage, semi-gloss black power coat finish to prevent corrosion and withstand the test of time.
