Will this kit work on my 4WD truck?

This kit is engineered for 2WD trucks only. The suspension geometry and load paths on 4WD models differ enough that this kit won't deliver the intended result—stick with a 4WD-specific leveling solution.

Do I need to install shocks or anything else while I'm in there?

The kit alone will level your front end. Whether you upgrade shocks or other suspension components is your call, but it's not required for the leveling kit to work. Many guys refresh worn shocks while they're doing the install anyway.

What tools and fasteners do I need to bolt this on?

You'll need basic hand tools and a jack to get under the truck. The kit assembly comes as shown above—verify all mounting points and fastener specifications against your truck's service manual before final torque.
