Description
Performance for the Trails and Smoothness for the Highway. Give your Sierra 1500 maximum off-road performance without compromising ride quality with the Rough Country 6-Inch Suspension Lift Kit with Premium N3 Shocks. This suspension lift kit will provide your truck with 6 inches of overall lift while simultaneously leveling-off the front to the rear. By doing so, this kit gives you the ideal ground clearance to negotiate more rugged terrain on larger 35-inch tires. Meanwhile, its leveled-off stance gives your truck a fierce style to match its muscular looks. More importantly, this lift kit retains your ride quality virtually at factory levels so you don’t lose its everyday drivability.
Premium Rear N3 Shock Absorbers. This suspension lift kit features a pair of N3 shock absorbers to provide excellent damping performance both on and off-road. This is achieved by combining 10-stage variable valving technology with a high-pressure nitrogen charge to provide a more immediate damping performance. This translates to improved handling control on the trails and a smooth ride on the highway. What’s more, these shocks utilize wider alloy shock bodies designed for more heat dissipation and 18mm chrome-hardened piston rods for maximum strength.
Hefty Front Steering Knuckles. This lift kit gets its front lift thanks to a pair of lifted front steering knuckles. These knuckles are also designed to restore steering geometry to near factory levels, ensuring your truck continues to handle as it should. Additionally, these knuckles are cast from high-quality steel and are finished in a corrosion-resistant protective coating.
High-Strength Fabricated Rear Lift Blocks. The rear lift is provided by a pair of lift blocks precision-fabricated from high-grade steel. These lift blocks offer exceptional strength and resistance to compression forces, unlike cast blocks. Moreover, these lift blocks are finished in a protective black powder coat finish that provides superior corrosion protection.
Heavy-Grade Strut Spacers. This suspension lift kit also includes a pair of strut spacers that enables you to reuse your factory struts for maximum ride comfort. Moreover, these spacers are precision-cut and fabricated from heavy-grade steel before receiving the same corrosion-resistant black powder coating as the lift blocks. This ensures these spacers are well-protected against rust.
Direct Install Procedure. The suspension lift kit’s various parts install onto preexisting locations on your truck. No welding is needed for installation but you will need to make minor cutting and trimming to properly fit certain components. A complete set of tools and advanced mechanical knowledge is also needed to keep the install as efficient as possible.
Features a Limited Lifetime Warranty. This Rough Country 6-inch suspension lift kit features a limited lifetime warranty covering factory defects. Please visit the manufacturer’s website for more details.
Application. The Rough Country 6-Inch Suspension Lift Kit with Premium N3 Shocks fits all 2019 to 2025 3.0L GMC Sierra 1500 models, excluding AT4s and Denalis.
Application Notes. Your factory wheels will not fit this suspension kit. Please use 20 inches or larger aftermarket wheels with a 4.50-inch backspacing.
