Engineered for hardworking emergency, municipal, fleet and jobsite vehicles, Monroe® Magnum® Severe Service shocks feature enhanced components for superior stability and ride control in the toughest environments.

• ENGINEERED FOR EMERGENCY AND FLEET VEHICLES -- For hardworking first responder, municipal, fleet and jobsite vehicles and features 10-stage valving that adjusts to road extremes to help handle frequent stops, heavy loads and high miles
• LONGER SERVICE LIFE -- Larger bore, bigger 2-in. reserve tube and 0.05-in. pressure tube work together to hold more oil for greater capacity to allow the shock to work efficiently for controlled ride and longer service life
• STRONG AND DURABLE -- Loop welding techniques include resistance welds and/or arc welds up to 360-degrees for durability while shouldered bushing and bonded bushing (on most applications) delivers quality
• BUILT TO LAST -- Heavy-duty nitrocarburized rod (on most applications) and sintered iron piston enhance durability for longer service life
• IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
• CONSISTENT RIDE -- OE all-weather fluid contains special modifiers to handle extreme temperatures and help reduce friction and ensure smooth rod reaction
• CONTROL AND DURABILITY – Banded piston helps reduce friction between the piston and pressure tube to enhance responsiveness to changing road surfaces for smooth operation
