Built for the ReadyLift 66-3086 Suspension Leveling Kit for 2014-2018 GM 1500 Trucks, this ReadyLIFT component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.

ReadyLIFT offers a solution for leveling 2014-2018 GM 1500 trucks. GM modified the upper control arms to stamped steel, which lacks support for the factory ball joint in lifted scenarios. GM prohibits lift or leveling kits for these vehicles. This kit is compatible with GM 1500 trucks with stamped steel or aluminum control arm suspension (not cast steel). You can identify your control arms [here](www.readylift.com/blog/2017/07/11/upper-control-arms). ReadyLIFT's solution includes a CNC machined billet aircraft-grade aluminum 2.25" leveling kit and durable DOM-tube steel upper control arms. These arms replace the factory stamped steel ones, featuring heavy-duty ball joints and maintenance-free anti-resistance bushings. This combination (PN 66-3086) levels 2017-2018 GM 1500 trucks, maintaining the factory ride and preventing stamped steel control arm failure. It allows up to 33x11.50 tires. Some vehicles may need the 15-3485 1/2" front wheel spacer with certain factory wheels. The kit includes CNC machined billet aluminum construction leveling kit, DOM tube steel upper control arms, heavy-duty ball joints, and maintenance-free bushings with "side biter" splined washers for alignment. To ensure proper fitment, measure from the wheel hub center to the fender's bottom edge at 12 o'clock while the wheels face forward. If it's over 22", the truck has pre-installed lift. Install the ReadyLIFT leveling kit without the lower horseshoe spacer for correct front lift height and suspension geometry. Incorrect use on trucks with over 22" may result in component interference and excessive wear. For more information, visit [here](www.readylift.com/blog/2017/07/11/upper-control-arms) or watch the [video](youtu.be/mGWolZSgu4k) about this kit. Some vehicles may require the 15-3485 1/2" front wheel spacer when using factory wheels, depending on wheel options and backspacing. To fit a 285 or larger tire on factory wheels, you may need 1/2" wheel spacers in front.

The ReadyLift 66-3086 suspension leveling kit provides an effective solution for leveling and enhancing the appearance of 2014-2018 GM 1500 trucks. Designed specifically for models with stamped steel or aluminum upper control arms, this kit addresses the support limitations of factory stamped steel components when lifting the vehicle. It includes a CNC-machined billet aircraft-grade aluminum leveling spacer that raises the front of your truck by 2.25 inches, restoring a balanced stance without compromising ride quality. The kit also features durable DOM-tube steel upper control arms equipped with heavy-duty ball joints and maintenance-free anti-resistance bushings, ensuring increased strength and longevity while maintaining factory ride characteristics. This combination prevents stamped steel control arm failure and allows for up to 33-inch tires, giving your truck a more aggressive look and improved off-road capability. For proper fitment, vehicle owners should measure from the wheel hub center to the fender's bottom edge at 12 o'clock while the wheels face forward; if the measurement exceeds 22 inches, the vehicle has pre-installed lift components. Some trucks may require the addition of 1/2-inch front wheel spacers, especially when fitted with factory wheels, to achieve optimal clearance and tire fitment. Installation is considered difficult and requires professional expertise, typically taking over five hours, and should be performed without the lower horseshoe spacer to preserve suspension geometry and avoid component interference. This leveling kit is compatible with a range of 2014-2018 GM trucks, including Chevrolet Silverado 1500, GMC Sierra 1500, and larger SUVs like the Tahoe, Yukon, and Suburban, offering a straightforward upgrade to improve both aesthetics and performance. For detailed instructions and product insights, visit the manufacturer's blog or watch the installation video linked above.
