Built for the ReadyLift 66-3085 Suspension Leveling Kit for GM Silverado and Sierra 1500 (2012-2020), this ReadyLIFT component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.

To run a 285 or larger tire on the factory wheels of your 2007-2020 GM Silverado / Sierra 1500 6-lug new body style pickup, you may need to use ReadyLIFT's 15-3485 1/2" front wheel spacer. This spacer is essential as factory wheel options and backspacing differ. This lift kit, known as the 66-3085, ensures that your factory springs are not compressed and does not require cutting the strut studs. Importantly, it will not affect your factory OEM ride quality or comfort level. The 66-3085 kit includes two Aluminum SST Strut Extensions and two Aluminum SST Lower Strut Mount Spacers, all constructed from CNC-machined 6061-T6 solid billet Aluminum. This high-quality construction ensures durability compared to cheaper kits made from low-grade stamped steel. Please note that this kit is compatible with new 2015-2020 GM 1500 Trucks. However, if your truck is a 2017 model with stamped steel upper control arms, it may require either aftermarket upper control arms or the purchase of Aluminum factory upper control arms. Stamped steel control arms on 2017 models are known to have issues with ball-joints when leveling or lifting the suspension. To determine the proper fitment of the leveling kit, use a plumb bob line to measure from the center of the wheel hub to the bottom edge of the fender at the 12 o'clock position while the wheels are pointing straight forward. If this measurement is greater than 22 inches, it means your truck already has some factory or aftermarket front lift compared to a base truck. For distances measuring greater than 22 inches, #66-3086 or #66-3085 should be modified to account for the pre-installed lift. Incorrectly using these kits on a truck with 22 inches or more distance may result in component interference and excessive wear. Additionally, some vehicles may require the use of 1/2" front wheel spacers when using aftermarket tires on certain factory wheels, but the factory wheel options and backspacing can vary.

Upgrade your 2007-2020 GM Silverado and Sierra 1500 trucks with the ReadyLift 66-3085 suspension leveling kit, designed to provide a 2.25-inch front lift for improved ground clearance and a more aggressive stance. This kit is ideal for fitting larger tires, up to 33 inches in diameter, on factory wheels while maintaining your vehicle's original ride quality and comfort. Crafted from CNC-machined 6061-T6 solid billet aluminum, the kit includes two aluminum SST strut extensions and two aluminum SST lower strut mount spacers, offering durability and resistance to wear compared to lower-grade steel alternatives. It is engineered as a direct fitment for 2012-2020 model year trucks, with specific considerations for 2017 models that may require aftermarket upper control arms if factory stamped steel components are present.

Installation involves professional expertise and typically takes around four hours. The kit does not require cutting of strut studs or compression of factory springs, ensuring a straightforward upgrade process that preserves OEM ride quality. Proper measurement from the wheel hub to the fender ensures compatibility, especially on trucks with pre-existing lift or aftermarket modifications. If the distance exceeds 22 inches, modifications may be necessary to prevent component interference and excessive wear. Additionally, some vehicles might need 1/2-inch front wheel spacers when using aftermarket tires with certain factory wheels to achieve optimal fitment.

It's important to note that this product is California Proposition 65 warning-labeled due to potential exposure to chemicals like DEHP. For best results, professional installation is recommended to ensure safety and proper fitment. The ReadyLift 66-3085 kit offers a reliable solution for drivers seeking a balanced lift, improved tire compatibility, and enhanced vehicle appearance without sacrificing ride comfort or safety.
