The GABRIEL 77810 31.53" Extended Length Monotube Shock Absorber is engineered to enhance the suspension performance of 1999-2004 Ford F-250 and F-350 Super Duty 4WD trucks. Designed for light off-road use, towing, and hauling, this shock absorber offers superior control and stability under demanding conditions. Its monotube design features a larger bore size, enabling quicker response times and a smoother, more comfortable ride. The single-tube construction and multi-stage sealing effectively minimize chamber temperature and debris intrusion, ensuring longer-lasting performance. The rod guide bearing system facilitates smooth and effortless movements, while the D.O.M. (Drawn-Over-Mandrel) tubing reduces internal wear, extending the product's lifespan. The chromed piston rod provides a consistent wear surface for proper seal lubrication, further enhancing durability. With an extended length of 31.53 inches, a collapsed length of 18.5 inches, and a stroke of 13.03 inches, the GABRIEL 77810 is tailored to meet the specific needs of Super Duty trucks, delivering reliable and consistent performance for fleet operations.
