The Monroe® Gas-Magnum® Rear Suspension Shock Absorber is designed for midsize and full-size trucks and vans, delivering firm control without a harsh ride. With up to twice the fluid capacity of standard 1-in. bore shocks, Gas-Magnum shocks work more efficiently with less effort.

A reliable, economical rear suspension replacement for Chevrolet and GMC full-size vans, SUVs, and Winnebago coach applications, backed by Monroe's Limited Lifetime Warranty and exclusive Feel the Difference™ Guarantee.

• Designed for Trucks and Vans: Full-displaced valving on compression cycles delivers controlled ride and handling.
• Built to Last: Heavy-duty nitrocarburized rod (non-dust shield units only) and sintered iron piston enhance durability; self-lubricating fluid seal reduces piston rod wear.
• Consistent Ride: OE all-weather fluid with special modifiers handles extreme temperatures and ensures smooth rod reaction.
• Improves Performance: Nitrogen gas-charge maintains tire-to-road contact by reducing aeration and shock fade.
• Longer Service Life: Larger bore and bigger 2-in. reserve tube hold more oil for greater capacity and long-term performance.
• Buy with Confidence: Backed by Monroe's Limited Lifetime Warranty and exclusive Feel the Difference™ Guarantee.
