Best coil spring rate for a TTB Bronco

[David Kennedy]

Hey guys,

I'm building a '96 Bronco for daily driving/ chase duty and need some help with front coil selection. Currently I have Autofab beams, radius arms, and coil buckets. The coils I've started with are Skyjacker's (part number 184S) rated at 580 lb-in. Unfortunately they are too stiff and the front end sits too tall. I'm considering a set of Rancho coils (part number RS609) that are rated at 460 lb-in. I'd also like to know if early-Bronco coils will bolt in to a TTB Bronco. Does anyone have any recommendations for me?

Thanks again,

David

I have dual rate coilovers with 350/400 springs. For a standard spring set up I suggest you call Camburg . My brother has them on his truck and they seem pretty supple.

If those are the "1.5 inch lift - aka "riser" coils, I have used them several times on F-150 and broncos. I don't have the part number handy - but the camber is off a little, which I believe could easily be overcome with a ball-joint shim. I never bothered, just ran a little "tall", but not bad. I do believe that is the correct part number - I've probably bought 3-4 sets over the years, and gave my last ones away when I went with dual coil-overs... although I think I'm 300/350 if my memory serves me correct. Dad has the truck, so I can't go look.

so, im not sure if it was on here, or on fsb but there was a guy that said he was using moog springs with a kit he was selling? anyone know anything bout these springs?? are they honestly worth a **** or??? I have superlift 2" lift springs on my ttb f-150,and these things are stiff as hell...

A spring is a spring, with the only difference being the rate and whether it actually fits. The rate is going to be dictated by the wire diameter and the number of coils. What does make a difference is the material it is made from, and some spring mfgs will only use domestically produced steel, because of problems with breakage. Where the Moog springs are made and what they are made of could make a difference. As far as rates, there are some kits that use OEM van springs, which tend to be longer and/or stiffer, and could be made to work. If you are on this forum, you are probably looking for a little more specific requirements. It all comes back to you get what you pay for. If the supplier has done the testing and has a bunch of examples out there that work, then you would extpect to pay a little more and end up with something you can use. The best you can do is ask a lot of questions and make your own decisions with the information. I even had some coils that Deaver sent me that I had to send back. After taking measurements of the wire diameter and the number of coils, they were the wrong direction from what we needed, and would have made the truck undriveable.

Then there is my local blacksmith that provides stuff that will NOT work AND charges too much! Never could get that guy to understand.
