The Gabriel 61641 ProGuard Shock Absorber is engineered to enhance the comfort and control of trucks, vans, and SUVs across diverse road conditions. Designed with a 1-3/8 inch bore piston, it offers greater durability and performance. The larger reservoir tube facilitates better cooling, reducing shock fade and extending the shock's lifespan. A piston seal minimizes oil by-pass, ensuring maximum shock control and performance. The super-finished chromed piston rod provides superior corrosion resistance and enhanced sealing properties. Additionally, the larger diameter piston delivers improved response and performance, resulting in sportier handling and a smoother ride. These features collectively contribute to a more stable and comfortable driving experience, reducing wear and tear on other suspension components and enhancing overall vehicle performance.
