I word to the wise
TT and shakle lifts are the cheap way....you get what you pay for, worn CV joints and replaced hubs, new axel seals...etc.
One alternative is a bodylift(3"), major pain, but and inexpensive non destructive lift.
The best lift out there right now for your truck is the Superlift kit(4"). They have engineered the best possible parts list for correct suspension geometry and least amount of stress on components. In my opinion, Trailmaster's kit is inferior in engineering.
As for install, someone said it already, nothing just bolts right up. You will have to cut one of the frame members to allow clearence for the lowering of the front diff, for example.
Expect to buy a double cardon front drive shaft, if you decide to use the stock shaft, expect to buy a new front axel(dana30 I believe) in a few thousand miles.
Research the kits, this is not something you want to just jump into real quick.
Good luck,
Matthew
