If you're looking for a serious lift for your truck, but want it to still be able to be a daily driver, you've found the right kit. You'll also be able to run much larger tires and wheels (see wheel size tab for more info on commonly used wheel and tire sizes.
The 6-8" kit (you will need to add torsion keys part CSK-C13-3
to go from the fixed 6" up to 8" in the front) includes a 1 piece gusseted sub-frame w/ steel full size differential skid plate, fabricated steel / CNC machined front steering knuckles, high strength steering drop center link w/ heim jointed support links to minimize wear of factory idler and pitman arms, differential drop brackets, heavy duty bump stop brackets, extended sway bar end links, brake line drop brackets, CST laser cut torsion drop brackets, all necessary hardware, and front stock shock extensions. Steering stabilizer brackets are built into the kit and CST's stabilizer shock kit CSR-2946

To lift the rear of the truck, this CST Lift Kit includes fabricated 4" lift blocks with bump stop pads and heavy duty 3/4" u-bolts. Extended length rear shocks are required and are available at an additional charge (above), or you can use another brand of your choosing.
