Quick Overview

The new design for the GMC Sierra 1500 and Denali models with a Gas engine is a head turner that transforms beautifully with the addition of a suspension lift kit. The Rough Country lift kit was engineered to provide a 6" level stance without sacrificing ride quality by utilizing optimal suspension geometry that gives your truck enhanced off-roading capability that doesn't affect the smooth handling and ride quality that makes these trucks so impressive.


Rear N3 Nitrogen charged shocks have 10-stage variable valving to create a fantastic blend of smooth street riding and off-road action. With a durable 18mm spring-loaded piston rod and faster-cooling 54mm shock body, this shock offers up to 36kN Tensile Strength for a long lifespan of impressive vibration dampening. Natural rubber bushings and an eye-catching metallic silver paint combine to make an impressive statement.


This lift kit allows 35x12.50 tires on 10" wide wheels with 4.5" backspacing without increasing the stock track width.
