The Gabriel 61664 ProGuard Shock Absorber is engineered to enhance the comfort and control of today's trucks, vans, and SUVs. Designed with a 1-3/8 inch bore piston, it offers greater durability and performance compared to standard shock absorbers. The larger reservoir tube increases fluid capacity, providing better cooling and reducing heat buildup, which is crucial for maintaining consistent shock performance under varying road conditions. The super-finished chromed piston rod delivers superior corrosion resistance and enhances sealing properties, extending the shock absorber's lifespan. Additionally, the leak-proof piston seal minimizes oil bypass, ensuring maximum shock control and performance. The Gabriel 61664 is gas-charged and features stud mounting types for both upper and lower installations, facilitating straightforward replacement and maintenance. This shock absorber is a reliable solution for fleet operators seeking to improve vehicle handling and ride quality, thereby reducing driver fatigue and enhancing operational efficiency.
