About this part

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

A 2-inch block and U-bolt kit for 2005-2010 Ford F-250 and F-250 Super Duty pickups. The fabricated steel blocks are 2.5 inches wide, taper to keep driveshaft angle in check, and locate on a single 9/16-inch pin. Round U-bolts are e-coated black and thread 5/8-inch, with a 3.625-inch inside width and 16.5-inch inside length. Overload-spring and dually trucks are excluded.

This 2-inch kit covers the 2005-2009 Ford F-250 in XL and XLT and the 2005-2010 F-250 Super Duty across Cabela's, FX4, Harley-Davidson Edition, King Ranch, Lariat, XL, and XLT, in 4WD and RWD. Fabricated construction rather than cast is the durability argument here, and the powder-coated blocks pair with corrosion-resistant e-coated U-bolts. Two things to settle before you order: rule out a dually axle, and check whether your truck runs overload springs, since neither is covered. Plan on 2-3 hours in the driveway.
