Cast Iron Rear Block Kit for Ford Super Duty (2011-2017)

Cast Iron Rear Block Kit, fitment-checked

Solid cast iron rather than aluminum or fabricated steel, with an integrated rear bump stop landing and a locating pin built in. E-coated U-bolts, nuts and washers complete the kit. Coverage is the F-250 Super Duty from 2011-2017 and the F-350 and F-450 Super Duty from 2016-2017.

The construction is the story on this one. The blocks are solid cast iron, with the rear bump stop landing integrated into the casting rather than added separately, and a locating pin to keep the block indexed on the spring pack. E-coated U-bolts, nuts and washers are supplied. Coverage differs by model: the F-250 Super Duty runs 2011-2017 while the F-350 and F-450 Super Duty are listed for 2016-2017 only, so check the year against your specific truck. Boxed weight is 23 lb.
