The Gabriel G64000 Ultra Truck Shock Absorber is engineered to enhance the performance and durability of heavy-duty vehicles. Designed for the rear position, it features a collapsed length of 17.68 inches and an extended length of 27.36 inches, making it compatible with specific models such as the 2003-2009 Hummer H2. This shock absorber incorporates Gabriel's exclusive G-Force„¢ Technology, which includes Infinitely Variable Damping for on-demand control across various road conditions. The StableSteer„¢ valving improves tire contact with the road, enhancing control, safety, and performance. A 1-3/8-inch bore piston with bonded iron construction ensures durability and a longer service life. The super-finished chromed piston rod provides superior corrosion resistance and enhances sealing properties. Additionally, the leak-proof piston seal and rod guide eliminate oil bypass, maintaining consistent performance. The OE-design single-lip oil seal minimizes friction, optimizing sealing efficiency. The bulged design increases fluid capacity, aiding in cooling and extending the shock absorber's lifespan. These features collectively contribute to a smoother ride and improved vehicle handling, addressing the operational challenges of maintaining vehicle stability and comfort under varying road conditions.
