Our 1500 4WD Bulletproof Suspension system has set the bar for the best lift kit on the market.

Bulletproof Suspension's 1500 4WD lift kit system for it's name sake is "Bulletproof".

Six shocks are required for this system and we offer standard shocks or Fox Racing Shox as options. Complete instructions with photos and hardware kit labeled for each step make the installation a breeze. We here at Bulletproof Suspension Inc recommend Atlas Rear Leaf Springs (quoted separately). No blocks, "Add-A-Leaf" or shackle extensions on our kit. At Bulletproof Suspension Inc. we don't cut corners and set you up right in the first time.

1999-2006 Chevrolet 1500 4WD have a reputation for wearing out factory idler arms especially when you install 37-38" tires. The design team here at Bulletproof Suspension Inc has added yet another stand above the rest improvement to our steering system in the way our manufactured 7071 aluminum billet steering arm drop downs. Our billet steering arms are further enhanced with 4140 chromoly bushings heat treated to ensure long life and are far superior to the factory component. The pitman arm powers the Bulletproof Suspension Inc steering system and allows your tire choice to turn freely without effort or strain on the system. Bulletproof Suspension Inc.'s Chevy 1500 4WD lift kit system tie rods, center-link and drag-link are made out of 1-1/8" O.D .219" wall thickness D.O.M. Tubing attached at all ends with our seven piece chromoly steel heim rod ends. This system is definitely "Bulletproof"

Bulletproof Suspension Inc. drops the differential to the full amount of the lift to maintain the suspension within factory specification and eliminate any extreme angles that come with other lift kit. In addition, bump stops and droop stops are added to ensure that there will be no over extending, compressing or binding in your suspension system. Another critical factory aspect of you truck is wheel track and wheel base. Bulletproof Suspension Inc. maintains the factory spindles keeping your track and wheel base and off-set stock. We also include Bulletproof Suspension Inc. torsion keys giving you the option of taking you truck up to a full 12" of lift ( hence the 10-12" ability ).

We here at Bulletproof Suspension Inc. know that your vehicle is important to you, and we've designed our Chevy 1500 4WD kit so that there is no need to remove the main boss from the differential like most of our competitors do. Keeping your critical factory components in tact is essential and not doing that is just a cheap short cut.
