About this kit
3.5-Inch Lift Kit with Red Forged Control Arms, fitment-checked
Same 3.5-inch geometry as the standard kit, finished in red: 11400RED supplies red forged aluminum upper control arms for 2021–2025 Tahoe, Suburban, Yukon and Yukon XL 4WD, with POM ball joints pre-installed. Requires 20in or larger wheels and minor trimming, and excludes Magnetic Ride Control and Adaptive Air Ride models.
This 3.5-inch lift kit for 2021–2025 Tahoe, Suburban, Yukon, and Yukon XL 4WD is the red-finish build: forged aluminum upper control arms replace the factory pieces to reset front geometry at the new ride height, with POM ball joints pressed in before the arms leave the box. Minor trimming is required, wheels need to be 20in or larger, and a mass damper on the front differential must come off. AT4, Premier, High Country, magneride, and Adaptive Air Ride trucks are not covered. A downloadable installation guide is available. Shipping weight: 25.0 lb.
