About this part
2-Inch FK/FF-Code Leveling Kit, fitment-checked
This is the FK/FF RPO code version of Rough Country's 2-inch torsion key leveling kit for 2001-2010 Chevrolet Silverado and GMC Sierra HD trucks. Yellow, tan, or purple factory keys are what it is built for — if you are unsure, the RPO label in the glovebox settles it. Shock extension brackets come along so the factory shocks carry over. A torsion bar unloading tool (Rough Country 1067) is needed.
Two things decide whether this is your part: the RPO code and the color of the keys already in the truck. Rough Country builds the 8597 for FK and FF codes and for yellow, tan, or purple factory keys, while FT-code trucks take a different number. Beyond that it is a straightforward front-end lift — forged keys, indexed to keep the arms and shocks working in their intended range, plus extension brackets that put the factory shocks back where they belong. A downloadable installation guide is available.
