Severe Service Ride Control products are engineered for emergency, municipal fleet and construction uses. These gas-charged, extra-durable Monroe shock absorbers feature strengthened components for superior stability and ride control in the toughest applications. Durable Severe Service shock absorbers have a larger bore for greater working capacity and arc-welded mounts for higher tensile strength. Product Features:Multi-lip fluid seal designed for smooth performance, long life and reduced frictionPowdered metal rod guide with DU bushing for better side load performanceLarger boreDrawn over mandrel pressure tube - improved tube strengthHeavy chrome rod - better finish for longer seal lifeNitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applicationsFluon Banded Piston: Enhances responsiveness to changing road conditions.10-Stage full displaced valving (on most applications)All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.Arc-welded mounts for improved tensile strength
