To run a 285 or larger tire on factory wheels, some compatible 2007-2018 GM 1500 6-lug truck and SUV applications may require ReadyLIFT's 15-3485 1/2" front wheel spacer due to differences in factory wheel options and backspacing.

The ReadyLIFT 66-3085 Front Leveling Kit provides up to 2.25 inches of front lift without compressing the factory springs or requiring permanent modification to factory components or cutting of the strut studs. The system is designed to maintain factory OEM ride quality and comfort.

The 66-3085 kit includes two Aluminum SST Strut Extensions, two Aluminum SST Lower Strut Mount Spacers, and the necessary installation hardware. The spacers are CNC-machined from solid 6061-T6 billet aluminum for strength and durability.

For 2017 models equipped with stamped-steel upper control arms, compatible aftermarket upper control arms or factory aluminum upper control arms are required. Stamped-steel upper control arms on these models can experience ball-joint issues when the suspension is leveled or lifted.

Before ordering or installing the kit, measure the vehicle's existing front ride height. With the wheels pointing straight forward, use a plumb line to measure from the center of the wheel hub to the bottom edge of the fender at the 12 o'clock position. A measurement greater than 22 inches indicates that the vehicle may already have factory or aftermarket front lift.

If the measurement exceeds 22 inches, ReadyLIFT specifies that the kit should be installed without the lower horseshoe spacer to account for the vehicle's existing lift and maintain proper suspension geometry. Installing the complete kit on a vehicle that is already above this height may result in component interference or excessive wear.
