Here is another 2008 Chevy 2500HD 4x4 that we installed the same 2.5" Top Gun Customz Torsion Key Leveling Kit the last Chevy got. This is a very popular product for our Chevy customers, due to it being adjustable. This Torsion Key can be clocked in 1/2" increments from 1" - 2.5" of lift. This gives our customers the freedom to set their leveling kit to the perfect height for their needs.
