08+ Leaf Springs in 99-07...Anybody done it?

[TxFireman1972]

Has anybody swapped 08+ springs on to 99-07 trucks? The 08+ springs are 8" longer and are supposed to ride alot better. The difference is the front hanger is 8" more forward. Curious if anyone has attempted it. I ran accross this on EBAY , just wondered if anybody had done it. 1999-2007 F-250 F-350 Superduty Leaf Spring Conversion:eBay Motors (item 250515443873 end time Nov-15-09 15:46:32 PST) I emailed him and asked about them. He told me: just think if you welded 8 inches onto the front of your current leaf springs…..the rear shackle and axle center pin remain in exactly the same place, its just that the front eye is moved forward by 8 inches….this actually makes the leaf springs the same length in front and in back of the axle like it should be….the 99-07 design is really a terrible design because of the shorter front section really affects ride quality and limits maximum load…. Like I said, we have them on all of our company 1999-2001 F350 duallies, and it makes a huge difference, both in ride quality and weight carrying capacity, and there were absolutely no issues with regard to axle location, simply removing the existing front hangers and replacing them with ours 8 inches further toward the front is all that’s necessary…. Well I've tried talking to the guy that has the listing. Not much luck on getting info out of him. I asked him if he would sell me a set of just the mounts and he told me he couldnt because this was the last set he was trying to clear out, thats why the price is so cheap. LOL I told him: Well I'm interested but want to see what the brackets look like. So send me a pic of them and we'll see what we can do. There has to be a way to let me see what they look like if you are "trying to clear out this last set". Why wouldnt a person just be able to get a set of factory mounts and move them forward 8 inches? Just put yourself in my shoes, would you spend $1000 on something that somebody doesnt even want to show you a picture of? He responded: Because: 1) you don’t know the correct location to mount them (not as simple as 8 inches forward) 2) what are you going to do when the main frame crossmember falls out (and it will if you do the sequence wrong) 3) how do you plan to handle the parking brake cables (existing bracket is 8 inches forward of existing spring mount) We’ve already figured out all these issues and several others that you will encounter….. Just heard back from him again, he told me: We are not going to send you a picture of the mounts for the simple reason that they can be copied……..that is the reason there is no picture of the mounts to begin with in the auction….if you are interested in this kit, you are welcome to do the buy-it-now…….if not, we understand and thanks for your interest…..Scott @ IST

SCAAARRRYYY.

I wouldn't spend that kind of money. If he is that worried about someone copying them then he is doing something wrong. People with integrity about their design will gladly show someone. He doesn't want to show you because then you will know you are overpaying, IMHO.

I would move the spring hangers forward and install the newer for springs. If the centers are the same (and they are since the beds are the same) then everything else should be trivial. I would do it. I've thought of doing it. I've done very similar things in the past!

While I agree with him that is MAY NOT BE as simple as 8 inches forward, if there is really any value to what he is charging, some will pay it some won't.

Just like the work I ask people to pay for everyday. I'll gladly show you exactly what you are paying for and what we are doing. If I take your money upfront so you can see it then I am doing something un ethical or that really does not have the value for what I am asking you to pay for.

I would not spend that kind of money on something unseen. I would imagine it could be done with some thoughtful measurements and relocation of items.

Take a look under a current 08 and up system to get a better idea as to what the new locations would be based upon the 07 and older ones.
