Ford-CSS-0507
NOW INCLUDING NEW ADJUSTABLE PANHARD BRACKET!
Over one year in prototyping, research and design went into developing this kit. 5 years of on road testing as of 2022. Our 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.
Application:
-Truck: 92-97 Ford F250/350 4x4
-Axle: 05-16 Ford F-250/350 Dana 60
Includes:
Additional Information:
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. There is no need for a custom cross member on 5 speed trucks at this height.
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
Some general dimensions that may persuade you to use this kit:Running a 275/70-18
Door handles will sit at 51" center-line. Front fender well will be 40". Hood to grill junction is 49.5"
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..

Very nice kit easy install these work great and a nice addition on our Lightning
The swap was pretty straight forward. The cables are huge compared to stock. Just be careful to wire the solenoid up right. Original starter had a spade wire connector but i replaced the oldie and the new one comes with a proper threaded lug. If you're trying to build reliability in these old trucks, I think these are a wise purchase. Old cables really were not sufficient.
everything fits perfect and works great
Started out needing the drivers side repaired, and figured if I do one why not do both.
Many times I have welded in reinforcement and so on to fix these and this kit here from experience makes life so simple I will not be using/doing anything else from here forward.
They fit perfectly in the cup on both sides, no gaps, no rivet holes lead to anything important behind. Comes with everything you will need aside from a 1/8” drill bit.
I recommend using a center punch to all of your holes so you don’t walk the bit given some of the holes are on slopes.
This brought my door handle from sloppy to sturdy and firm and I don’t see it getting sloppy again.
Incredibly happy worth every cent.
Purchased the 10” of travel Bilsteins for my 1984 bullnose to pair with a 99 Dana 60 RSK swap. Came quick and price was very competitive. Plan to purchase another set for the rear now to match my Sky's shackle flip.
I would have had to modify these pieces quite a bit to get them to work. Disappointing thought I found the answer to my problem. But it won't stop me from trying other products OBS makes.

Quality product. Everything was included down to washers. And it fit exactly how the directions said it would.
