aFe CONTROL Leveling Kits are made of 6061 billet aluminum and provide a 1.5-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 1.5-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. Minor trimming of the upper studs on the factory struts is required for this install. A vehicle alignment is required after installing this product.
