Sky's Offroad Design 05+ Super Duty Axle Swap Kit
Over one year in prototyping, research and design went into developing this kit. 5 years of on-road testing as of 2022. Sky's kit addresses the many shortfalls with other kits on the market.
What it is: Laser cut on a 6000 watt Mazak fiber laser for quality, CNC formed with Mazak 150 ton press brake and welded to perfection. Brackets are 1/4" A-36 PnO steel. This material is superior in strength and cleaner than run of the mill aftermarket products. Not plasma cut mill scaled plate, which is soft, impossible to coat decently without sand blasting, and will leave porosity in welds.

Donor axles needed for the swap. 05-16 front Dana 60 from F-250/F-350. Axle, radius arms, trac bar, coils, sway bar with links, steering from pit man down. 8x170 bolt pattern. 05-10 F-450 axle 10 lug can be used but will require rear 10 lug DRW axle.
Rear axle can be 99-16. The 05-16 axle is preferred for larger brakes. The 08-16 axle with leaf springs is best if using the Ford-RSDSW leaf spring swap kit. 2wd conversions should acquire the factory rear block from the 4wd. For stock height leveled setup our 4" RSDSW can be used to eliminate the block for a net zero lift.
Kit is designed as a 1-2" lift over a factory F-250 2"/F-350 1" using a 4400 lb spring rate coil. This spring is a ADD code. This is also dependent on your trucks wheel base configuration, a std cab does not weigh the same as a crew cab long bed.
The following is other various spring rates. -5310-AHD = 6000 -5310-AGD = 5600 -5310-AFD = 5200 -5310-AED = 4800 -5310-ADD = 4400 -5310-ACD = 4000
This kit can be used with most Super Duty lift components that retain the factory frame brackets. The coil buckets add about 1.5-2" of lift over whatever spring you use.
If you have an unknown front axle, the sway bar links will be the best way to determine what you have. They are as follows:
05-07 bushing on bottom, stud top
08-10 bushing top and bottom
11-16 stud top and bottom
FITMENT NOTES: Where the coil buckets and radius arm mounts the frames are all the same from 80-97 F150 through F350. Where the track bar (panhard) mounts on the frame rail there is an additional layer of 1/4" steel that wraps around to on the bottom of the frame rail on some 80-91 trucks. This requires a 1/4" shim to give the bracket a surface to mount to.
This piece is circled in the image below. This is how the bracket is supposed to sit as demonstrated on the 92-97 frame it was designed for.
Sky will be making a shim for this in the future.
All Sky products have at least 2 weeks lead time.
