ReadyLIFT 4" SST Lift Kit for 2019-2024 Chevrolet Silverado 1500 & GMC Sierra 1500

The ReadyLIFT 4" SST Lift Kit lifts the front and rear together, so the vehicle gains clearance without losing its balanced stance. Each component is matched to this platform's factory suspension rather than adapted from a universal part. ReadyLIFT kit 69-39400 is engineered for the 2019-2024 Chevrolet Silverado 1500, Silverado 1500 LD and Silverado 1500 LTD and GMC Sierra 1500.

What's Included:

Wheels, tires, alignment, headlamp aiming and ADAS recalibration are not included.

Features

Lift at both ends
SST kits raise the front and the rear, unlike a leveling kit that only lifts the nose. The result is added clearance with a stance that still looks planned.

Room for larger tires
The added height opens the wheel wells for a bigger tire package. ReadyLIFT lists a tested tire size for every application.

Engineered per platform
ReadyLIFT designs each SST kit around one vehicle's suspension layout, so brackets, spacers and arms fit that platform rather than a universal pattern.

Keeps a usable rake
Most SST kits leave a slight rear rake so the vehicle sits right when it carries weight or pulls a trailer.

Built to keep factory manners
ReadyLIFT's stated aim for its mild lifts is added clearance without giving up the ride and handling the vehicle had from the factory.

Complete kit per application
Each kit ships with the lift components ReadyLIFT specifies for that vehicle, listed in the kit contents on every product page.

Tire fitment (ReadyLIFT's published guidance for this kit)

Tire and wheel sizes vary by manufacturer, so test-fit your combination before installation.

Installation

Type: front and rear mild lift  ·  Install: per-vehicle, see each kit's install sheet  ·  Afterward: alignment, headlamp aim, ADAS check

This kit installs using the steps in ReadyLIFT's instructions for this vehicle. Plan on a wheel alignment after installation and have headlamp aim checked. Vehicles with camera, radar or sonar driver-assistance systems need those systems checked and recalibrated, which can require dealer tools. ReadyLIFT recommends installation by a certified mechanic and says to read the full instructions before starting. Tire sizes are ReadyLIFT guidance based on specific wheel and tire brands, so test fit every combination. Larger E-rated tires have stiffer sidewalls than stock C-rated tires and can make the ride feel firmer.

ReadyLIFT estimates about 4.5 hours for this kit, give or take 0.5 hours, not counting the alignment or mounting wheels and tires.
