I first installed Camburg 1 1/2 inch collars on my truck, didn’t like how much lift they gave me and was not impressed with how the OEM suspension couldn’t handle the additional pre-load tension of the coil. Definitely didn’t ride as well dampened as I had hoped.
I then installed a set of 1” Eibach springs and they were a vast improvement over the collars, but still left a little to be desired on how they handled down travel, as again, the OEM shocks aren’t tuned for added tension of the Eibachs and the rebound was too fast for my liking.
So I decided to upgrade to the fox race series, coil overs, even though they are not application specific. I can say that these are far better than any of the previous lifts that I had done. Obviously as they are tuned to work with the spring that they have installed on them. I added a little bit of preload based on some of the left I’ve seen from other people doing the same thing, however, they seem to lift my truck a little bit more than some of the other people I have seen online. I only added 1/2 inch a free load to the collar and they actually gave me about 2 inches of lift. I am going to take all the pre-load out of the collar, just like how they came, and that should give me right around 3/4 of an inch to 1 inch of lift over the OEM set up. There is such a night and day difference between the ride of these coil overs, and doing a lift collar or springs that it isn’t even funny. I wouldn’t even waste my time with any other set up. I wish I didn’t waste the time and the money with those cheaper options.
As the truck sits right now, it is at 43 inches in the front, and 42 inches in the rear. It has 37 inch BFGKO2 tires.
