These spring brackets are designed to mount onto 1967-72 Ford half ton 4wd trucks and allow you to install either 2008-16 or 2017+ Super Duty leaf springs. Please compare your truck to the diagram before ordering.
These work well with either OEM axles or 2005+ SD axles.
Skyjacker FR173S is a 2017+ leaf option. It is fairly stout and has more load capacity than you likely need. it rides well for how stout it is.
Skyjacker FR84S is a 2008-16 leaf option. It is plenty capable and is a little softer than FR173S. It should have more capacity than any half ton application could use.
Both 2008-16 and 2017 Super Duty leaf springs are a massive 65" eyelet to eyelet. The main difference between the two types is the 2008 style has a 20mm forward bolt while the 2017 style has a 7/8 (really a metric equivalent) forward bolt.
Every bracket uses at least one factory drilled frame hole to make alignment and installation easier. You do need to drill a grand total of ten 7/16" holes in your frame. The brackets work as a template for the drilling location.
This can be used with your original Dana 60, a new super duty axle etc. Either way you do need to cut your factory perches and weld new perches meant for a 3" wide spring.
This listing includes all four brackets, enough to swap out both of your rear springs for super duty springs. 16 new 7/16" grade 8 bolts and all metal lock nuts are included.
You will need to separately purchase these things:
- Rear leaves
- lift block as needed
- Axle leaf spring perches for 3" leaves and axle tube diameter
- Leaf Spring plate for 3" leaves and axle tube diameter
- Leaf Spring Shackles for 2008-new Super Duty. Cheap ebay ones are fine.
- U Bolts- 5/8", width matched to axle tube diameter. No lift block = about a 9" U bolt so add your block to that. A 10" long U bolt is good for most applications.
- 7/16" Drill bits for bracket mounting
The red truck shown in the pictures here has Bilstein 33-230320 shocks. It has FR173S leaves and a 1" lift block.
