ReadyLIFT SST 4" Lift Kit For 2019-2024 Chevy/GMC Silverado/Sierra 1500 2WD/4WD

Upgrade your 2019–2024 Chevy Silverado or GMC Sierra 1500 with the ReadyLIFT 69-39400 4" SST Lift Kit. This premium no-cut kit provides a 4" front and 3" rear lift while preserving factory ride quality and handling. Designed for trucks equipped with or without Adaptive Ride Control (ARC), the kit includes heavy-duty steel strut spacers, CNC-machined billet aluminum preload spacers, and tubular upper control arms with corrected ball joint angles and maintenance-free TCT bushings. The rear lift utilizes 3" OE-style cast iron blocks and extended U-bolts, adding a subtle rake that enhances both towing capability and vehicle stance. This system allows up to 295/65R20 tires on 2019–2022 Chevy trucks and up to 295/55R20 on 2019–2024 GMC and 2023–2024 Chevy trucks.

This kit is intended for use with traditional steel leaf spring setups and is not designed for extreme off-road abuse. Some 2025 models may require U-bolt part #67-35120UB for proper fitment.
