The SuspensionMAXX SMX-166310 is a heavy-duty rear block and U-bolt kit engineered to provide a 1-inch suspension lift. This component is specifically designed for the 2011-2013 2WD Ford F-350 Super Duty models that feature a top-mount overload spring. Beyond simply lifting the rear suspension, this kit offers a practical solution for leveling vehicles that are subjected to heavy loads. By utilizing block-style lift technology, it effectively raises the rear of the truck, contributing to a more balanced stance when hauling or towing. This kit includes the necessary U-bolts and blocks for a complete rear lift installation. As a "Block" lift type, it is a straightforward method for achieving increased ride height and load-carrying capability. Always ensure compatibility with your specific vehicle configuration before installation.
