Hey everyone, this is one of my first post so bear with me ... I have a 1997 Ford F-250 SB CC 4x4 7.3
Just had a OBS sky 2.5in. reverse shackle with my stock 215k mile OBS leaf springs installed.
Converted to the Dana 60 straight axle
2.5 lift block in rear, stock springs.
It has pretty heavy weight up front with the Buckstop Winch bumper w/ 12klb winch.
THE PROBLEM I have is truck has so much bounce in the front end, it’s not very drivable. Not side to Side just up and down like a low rider. Definitely cant trailer anything which is what I mostly use the truck for, mainly just a car at a time, not big heavy loads or anything.
Does anyone have any advice if I should:
1. Buy 43-630-HD OBS springs for the front? Will prob lift it another 2in but need to get the ride back.
2. Take off the OBS kit and install the Sky Super duty kit front and rear ( I know that’s what should have been done in the first place)
3. any other ideas?
Advice is greatly appreciated, I’m kinda stuck on what to do next. Thanks
Yes and no. The SD springs are a different length, so you would need the SD RSK springs kit if you decide to go that route. It sounds odd but the OBS 250 springs are stiffer than the OBS 350 springs are. The TTB Dana 50 needs the additional stiffness. The easiest thing would be to install OBS 350 springs
Obs 350 springs will fix you up. You cant use 250 springs on straight axle.
You can do sd rsk and sd springs if you want to spend more money. Supposedly the ride is better. I have not spent enough time in sd rsk trucks to notice much diff.
i did however have rsk on my f350 for years with original springs. It was an improvement but not a luxury auto by any stretch.
This comes down to budjet. 300 or 800$....
Thanks for The response guys...Very helpful!
I’m going to post pics of springs I’m thinking about buying. Please let me know if you disagree or have any input on the OBS HD springs for my reverse shackle kit
my only concern is that it will lift the front a lot. Guess I can adapt the rear if I need to.
thanks again!
I am not smart enough to know if those are for an OBS or not. If they fit then they should work. Are you going to put a brush guard or anything on it? Do you have an adjustable lanyard bar or a drop bracket? With the RSK and the lift from the springs you will probably need at least one.
Yes I’ve been talking to them through all this and they told me about them for the SD kit, I haven’t looked for the OBS kit or was not mentioned.
This is what they sent me:
SD kit, For the panhard bracket, if this ends up being 3.5 or more lift in the front with those springs (SD HD) I'd recommend either doing the FORD-PHBF-3"-Raw or the FORD-DropPlate-3"-Raw
Just my $.02...I would contact ATS (ask for JR). He is also a member here "ATS JR" and is great to work with. I have purchased a few set of springs from them over the years. Great dude and very knowledgeable about these set-ups on the OBS trucks as well as the SD trucks!
He will give you solid advice for your application/desired ride and lift.
The image shows up now. It says it is for an F superduty. It may be a little stiffer than needed. Do they have springs for a 350? I would second ATS. They have a good reputation around here. You can get an adjustable panhard for either kit. Mine is for the OBS springs. When I talked to them about different kits they mentioned that smallest kit for an OBS was about the limit before needing an adjustable one. If the springs lift it more you may want to keep the bar in mind
I'm taking my SKY RSK OBS system off my 96 F350.
Have original Ford springs with 100,000 miles and bushing are still like new.
Have SKY track bar drop as well.
Make offer.
