i did the hockey puck lift on my old Tracker trail rig/dd. it did fine for the 3 years i owned it after the lift. no splits, chipping, cracking, etc with the pucks. no body mount damage at all. i road it pretty hard on the trails, and it still was used to get me to work and back. no driving issues at all. cheap and easy lift to be sure. others here will have different opinions, but that is mine from experience.
regular body lifts can be bought for your truck, and depending on where you live, you might want to consider replacing the original body mounts as well. here, where there is an annual freeze/thaw cycle, those rubber parts don't last as long as where the temps are more stable.
just my $.02.
