3. Operation & Performance

The Monroe Gas-Magnum shock absorber is engineered to provide superior ride control and handling, especially for trucks and vans that frequently carry heavy loads or operate in demanding conditions.

3.1 Key Performance Features

• Designed for Trucks and Vans: Engineered with full-displaced valving on compression cycles to deliver controlled ride and handling for hardworking full-size vehicles.
• Consistent Ride: Features OE all-weather fluid with special modifiers to handle extreme temperatures, reducing friction and ensuring smooth rod reaction for a consistent ride.
• Improved Performance: A nitrogen gas-charge maintains tire-to-road contact, improving ride and handling by reducing aeration and shock fade.
• Longer Service Life: A larger bore and bigger 2-inch reserve tube work together to hold more oil, increasing capacity and allowing the shock to operate efficiently for a controlled ride and extended service life.
• Built to Last: Incorporates a heavy-duty nitrocarburized rod (on non-shield units) and a sintered iron piston for enhanced durability. A self-lubricating fluid seal reduces friction against the piston rod, minimizing wear.
