aFe CONTROL Leveling Kits are made of billet aluminum and provide an adequate lift to the front of your vehicle to improve off-road performance while also eliminating the “nose-down rake” from the factory stance. This kit includes both shim and preload spring spacers, allowing for a range of lift heights. Using both provides the maximum 3.0-inch lift while maintaining proper operation of the factory shock and spring assembly. The included relocation brackets reposition the factory ride-height sensors for the increased front ride height, helping prevent drivability and transmission shift issues during hard acceleration. Constructed from 304 stainless steel, the brackets provide excellent corrosion resistance and long-term durability in harsh environments. Installation requires removal and disassembly of the front strut assemblies. A suitable spring compressor is required to install the preload spring spacers.
