Skyjacker's 3.5-inch lift kit for 2019–2021 GMC Sierra 1500 (crew cab, short bed) includes rear Nitro 8000 shocks and heavy-duty upper control arms to raise ride height with a bolt-on fit. Replaceable, greasable pivot ball joints and high-strength DOM tubing improve serviceability and strength, while gusset plate stiffeners add rigidity. The kit aims to preserve steering geometry for lifted applications.
