          Improve ride comfort, handling, and vehicle stability with this Monroe Suspension Shock Absorber. It is designed to help control suspension movement, reduce road vibrations, and maintain consistent tire contact with the road for a smoother, more controlled driving experience.

          Why replace this part? Worn shocks or struts can lead to excessive bouncing, poor handling, uneven tire wear, and reduced ride comfort. Installing a new Monroe Suspension Shock Absorber helps restore proper damping control, stability, and a smoother, more controlled driving experience.

          Key Features & Benefits

          • Improved handling and performance — Cross Tuned technology featuring exclusive rebound valving system and advanced compression phase improves overall handling and performance on and off road.
          • Minimizes rough ride — Exclusive Progressive Engagement Valving is custom-tuned for each vehicle to help reduce initial impacts at low speeds and minimizes a rough ride.
          • Strong and durable — Features a 16mm nitro-carburized piston rod to resist scuffs & corrosion, double-welded loops at stress areas, 35mm sintered iron piston for enhanced structural integrity and polyvinyl protective boot.
          • Handles extreme temperature changes — Large twin-tube body filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F.
          • Smooth performance — Polyurethane rebound bumper and rubber bushings help absorb ride harshness while the fluon-banded piston enhances responsiveness to changing road conditions for an overall smoother ride.
          • Reduces fade — Nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixture to reduce damping performance fade and foaming.
          • Maintains vehicle control — Compression Control Valve is custom-tuned for each vehicle to regulate fluid transfer to absorb impacts without disc flutter and help maintain shock motion control.
          • Built to last — Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the application-specific piston delivers heightened control of shock motion due to the expanded piston area.
          Product Overview
