About this part

Rear Kit with Dually Spring Pack, F-250 to F-450, fitment-checked

The three Super Duty sizes are covered over different spans here, and only the F-350 row is narrowed by trim — King Ranch, Lariat, XL and XLT.

Read your own row rather than the part as a whole, because the three sizes are not treated alike. The Ford F-250 Super Duty runs 2011 to 2017 with no trim condition. The F-350 Super Duty runs the same years but only in King Ranch, Lariat, XL and XLT. The F-450 Super Duty is limited to 2016 and 2017. All three share the contents: a dually rear spring pack, solid cast iron blocks with integrated rear bump stops, a locating pin, E-coated U-bolts, nuts and washers.
