Description
Enhanced Suspension Lift. The Rough Country 6-Inch Suspension Lift Kit with Premium N3 Shocks significantly raises the GMC Sierra 1500’s stance, delivering aggressive styling and increased ground clearance. It is engineered to accommodate larger tires and enhance off-road performance while preserving factory suspension geometry.
Construction and Appearance. Constructed from durable, high-strength components, this kit includes precision-fabricated knuckles, crossmembers, brackets, and lift blocks designed for optimal strength and longevity. The premium N3 shocks provide improved performance, and all parts feature a protective coating to resist corrosion and wear for lasting reliability.
Installation. Installation requires moderate mechanical skill with an estimated timeframe of 8-10 hours. Minor cutting and drilling are necessary for proper installation, so appropriate tools and preparation are recommended.
Warranty. This suspension lift kit is covered by a limited lifetime replacement warranty against manufacturer defects.
Application. Specifically designed for 2025-2026 4WD GMC Sierra 1500 models equipped with the 3.0L Duramax engine. It does not fit Denali, Denali Ultimate, AT4, or AT4X models due to incompatibility with Adaptive Ride Control and factory-installed lift systems.
