Product Details

ReadyLIFT is now shipping a premium-grade lift solution for the all-new 2021-2026 GM 1500 SUVs (2WD/4WD. Our new 69-31300 3" SST Lift Kit is engineered specifically for the new Chevy Tahoe, Suburban and GMC Yukon vehicles with standard coil suspension. (Kit excludes models with Magnetic Ride). ReadyLIFT 69-31300 has been engineered to provide 3 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, a much taller stance, and the comfort of knowing our engineers thought of everything when they developed this lift kit for full-size GM SUVs. The new 69-31300 3" SST Lift Kit 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 SUVs 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.

Part 69-31300 is the ideal bolt-on, no modifications required lift solution to achieve a substantially taller stance, all while maintaining the factory ride and handling experience. With this new SST lift kit, you can run up to a 285/60-20 tire on a +18 offset wheel with no trimming. A 295/60-20 with a 0 to +14mm offset can be installed with trimming.

Note:  Not for use on Magnetic Ride. (Will not work on - Premier, High Country, AT4, and Denali.) Note:  Not for use with GM Super Cruise or GM Ultra Cruise.  If using Chevy Tahoe Diesel a tire size of 285/60R20 +18 will require trimming or recommend a smaller tire size. Will not work with stock OE wheels.
