Dually Rear Spring Pack Kit for Ford Super Duty

Dually Rear Spring Pack Kit, fitment-checked

Built around a dually rear spring pack, which narrows it considerably. This is for the twin-rear-wheel trucks, not the single-rear-wheel ones.

The contents name the audience. A dually rear spring pack is part of this kit, so it belongs on a twin-rear-wheel truck rather than a standard one, and that is a bigger constraint than any trim list. Alongside it come solid cast iron blocks with integrated rear bump stops, a locating pin, E-coated U-bolts, nuts and washers. Coverage is the Ford F-250 Super Duty from 2011 to 2017 and the F-350 and F-450 Super Duty from 2016 to 2017: the F-250 row reaching back six years further than the other two.
