I decided to try and install my 3.5" deaver rear springs by myself today. I have a couple of questions for you guys. My truck was alrready lifted about 3.5" in the rear but when I pulled off the old springs it was 4leafs and an overload leaf. Isn't that stock? How could It be lifted. I thought maybe i had a reverse shackle? But it looks to be stock. The other question I have is. When I bought the deavers I purchased new bushings and sleeves for it. the pachage comes with 2 small sleeves(front shackles?) and 6 larger sleeves(rear shackles?). I took the bushings and sleeves out of the package to pre-fit. How and the world is that bolt suppose to go through that sleeve? It doesn't look like it fits. Am I suppose to pound it in?
