I believe that the Spyderlocks are aonly available in 3.5" backspace which would be ridiculous for these trucks. You will want to stay around 4.5-5" of backspace on a 9" wide wheel for a long arm kit on these trucks.Want to fit 38" tires on it that way 37" tires won't rub. Poison Spyder 17x9 beadlocks. At least 4" over stock to clear the bigger tires but mainly a lift that flexes extremely well. Looking at trying to keep it around $2500 but can be flexible with the right set up.
Unfortunately there isn't alot available in that price range that won't have you upgrading and replacing parts down the road. If you want to do it once and do it right I would suggest the following setup:
Pure Performance PW 4" X-factor system minus the rear lift components
Pure Performance forged drop pitman arm
Carli 4" rear full leafs made by Deaver
Bilstein 5100's or something custom from Carli like the Performance 2.0's valved for a Hemi truck.
Depending on shock options something like that would end up just under $4k.
