2-Inch Block and U-Bolt Kit for Ford F-250 Super Duty

2-Inch Block and U-Bolt Kit, fitment-checked

For 2011-2016 Ford F-250 Super Duty trucks, this 2-inch kit combines fabricated steel blocks with semi-round U-bolts, a different bolt profile than the round-style sets used on earlier Super Duty applications. Blocks run 2.5 inches wide with a single 9/16-inch pin and a powder-coated black finish; the U-bolts thread 5/8-inch with a 3.125-inch inside width and 15.25-inch inside length. Dually and overload-spring trucks are not covered.

The 2-inch kit for the 2011-2016 Ford F-250 Super Duty covers XL, XLT, Lariat, King Ranch, and Platinum in 4WD and RWD. Steel blocks are fabricated rather than cast, and each one tapers to hold driveshaft angle down after the change in ride height. The semi-round U-bolt profile is the detail that matters at ordering time: confirm the 3.125-inch inside width and 15.25-inch inside length suit your spring pack, and rule out overload springs and a dually axle first. Install runs 2-3 hours.
