The Monroe Shocks & Struts Shock Absorber is the perfect solution for class 3-6 vehicles. This gas-charged shock absorber provides a stable ride and quicker response, making it ideal for high mileage and severe use trucks and buses. With its exclusive 10-stage valving, this shock absorber provides consistent control at all speeds, ensuring a smooth and comfortable ride. The robust hydraulic lock-out feature prevents over extension of air bags, top-out of the piston, and damage to the seal assembly, making it a reliable and durable choice for your vehicle. The bearing with Polytetrafluoroethylene coating reduces friction between the rod and rod guide, while the nitro carburized piston rod provides 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®.
