Description
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.
Please note: this kit is not compatible with Trail Boss, ZR2, AT4, AT4X, or 2019 Silverado/Sierra Limited “LD” old body style models. It is also incompatible with trucks featuring mono-leaf rear springs, identifiable by round U-bolts. Super Cruise and Auto 4 Hi are not supported. 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. Always confirm your vehicle’s suspension configuration before purchasing.
