aFe CONTROL Leveling Kits are made of 6061 billet aluminum and provide a 2.0-Inch lift in the front to provide better off-road performance while also eliminating the ?nose-down rake? notorious on stock trucks. High quality hardware is used for strength and durability. Installation of these 2.0-inch leveling spacers can be done at home with the proper tools and safety precautions. Installing these spacers does not require disassembly of the strut/spring.
