QUICK OVERVIEW

ReadyLIFT is excited to offer a newly redesigned leveling kit for the GM 1500 series 2WD & 4WD trucks. The new design provides a leveling solution via an all-new upper strut spacer instead of the horseshoe bottom strut design. This new design helps with the installation process with less risk of contacting the CV boots when not installed properly. These new kits offer a 1.5" leveling solution for the new body 2019-2023 Chevy Silverado and GMC Sierra 1500 trucks. The leveling kit spacers are manufactured from CNC-machined 6061-T6 aircraft-grade Aluminum with a unique design to work with exclusively the 2019-2023 GM 1500 struts.



The 66-39150 leveling kit is specifically designed for the GM 1500 trucks without Adaptive Ride Control whereas the 66-39151 provides two extra brackets to work on GMC Denali and Chevy High Country 1500s equipped with ARC.



This all-new leveling kit will allow for up to a 33x11.50-20 tire on a 20x9 0 offset wheel (same wheel/tire specifications as the 66-3920 & 66-3922).



NOTES: (1) Not compatible with Chevy Trail Boss and GMC AT4 / AT4X suspension. (2) Not compatible 2019 Limited OLD Body Style. (3) Some wheels may require 6mm or greater wheel spacer to clear the brake caliper.

TIRE FITMENT

Denali trucks can accept a maximum tire size of 33x11.50-20 on 20x9 0 offset. Some minor trimming may be necessary depending on tire tread design.

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
