Tony,
What I have are the rear portions of the RCD lift kit (extended shackles, add a leaf, pinion angle shims, u-bolts, bump stop relocation blocks, and Bilstien 5100 extended shocks (still on truck but will be available shortly)). They were for the RCD 5" lift kit. They should fit your truck. The front portion of the lift was sold several months ago and would not have fit your truck. The spindle lift is probably still your best option for the front of the truck. Shackles and add a leaf might make the back of your truck too tall with a 3" spindle lift, assuming you left the factory lift block. If you removed the factory lift block, it might be just about right. If you are interested, I am looking to get $250.00 for the rear parts (including the shocks) or $200.00 without shocks. For your application, you might want to get new shocks based on the amount of lift that you get. Good luck and let me know what you want to do. I will watch for a used 3" spindle lift.
