Product Details: The Monroe Shocks & Struts Shock Absorber is the perfect solution for class 3-6 vehicles. This shock absorber is designed to handle the demands of high mileage and severe use, providing a stable ride and quicker response. Featuring an exclusive 10-stage valving system, this shock absorber provides consistent control at all speeds, ensuring a smooth and comfortable ride. The robust hydraulic lock-out prevents over extension of air bags, top-out of the piston, and averts damage to the seal assembly. The bearing with Polytetrafluoroethylene coating reduces friction between the rod and rod guide, combined with nitro carburized piston rod, providing durability and longer service life. This shock absorber delivers exceptional control and isolates impact-related noise, vibration, and harshness under most driving conditions. FleetPride is your First Click in Heavy Duty®.
