I've got a 99 F-150 that sags very bad with a load in the back or hauling a trailer? Anybody have experience with helper springs? Do they help? Anybody know of stiffer springs that will swap into an f 150? Any suggestions will be taken, thanks guys
you can check jegs they have spring helpers for your truck, they have most common parts for all the american made trucks, or you can look into AAL for your make and model.
I found some, I was just wondering if anybody had used them with good or bad results
the front springs for a OLDER f250 or 350 are the same length if i remember right
i added a few leaves to mine to help out with that
