ReadyLIFT is now shipping a premium-grade lift solution for the all-new 2021-2023 GM 1500 SUVs with (2WD/4WD) Magnetic Ride Control. Our new 69-31301 3" Smart Suspension Technology (SST) Lift Kit is engineered specifically for the new Chevy Tahoe, Suburban and GMC Yukon vehicles compatible with Premier, High Country, AT4, and Denali models or models equipped with Magnetic Ride Control. ReadyLIFT 69-31301 has been engineered to provide three inches of lift height overstock, without over-lifting. Three inches of lift is perfect for installing a plus-1 or plus-2 larger tire and wheel combination without sacrificing the plush factory ride and handling of these new GM SUVs. Enjoy increased ground clearance with a much taller stance. Take comfort in knowing our engineers thought of everything when they developed this lift kit for full-size GM SUVs. The 69-31301 3" SST Lift Kit for new GM SUVs equipped with Magnetic Ride Control is the highest-quality, best-engineered bolt-on lift system you can install on a new GM SUV. The kit includes our popular ReadyLIFT tubular control arms with corrected ball joint cup angles, heavy-duty one-ton ball joints, and maintenance-free non-bonded TCT pivot bushings that ensure proper suspension geometry and functionality. The front lift is achieved with new heavy-duty steel top mount front strut extensions, while the rear is lifted with fabricated steel top mount spacers and CNC-machined billet Aluminum rear coil spring pre-load spacers. The rear pre-load spacers serve the GM SUV's well by adding just a touch of rear spring rate, ideal for preventing rear sag when the vehicle is loaded down or carrying many occupants. This new kit checks all the boxes. We even include new relocation brackets to allow for slack on critical suspension sensor wires. Note:   Not compatible with Air Ride Adaptive Suspension. Note: Not compatible with GM Super Cruise or GM Ultra Cruise.
