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.

Built for hardworking trucks and vans, the Gas-Magnum provides firm, controlled rear suspension performance with its larger bore and increased oil capacity, allowing it to operate efficiently under demanding conditions.

• DESIGNED FOR TRUCKS AND VANS: Engineered for full-size trucks and vans with full-displaced valving on compression cycles for 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 friction and 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 2-in. reserve tube hold more oil for greater capacity and controlled ride over time.
• BUY WITH CONFIDENCE: Comes with Monroe's Limited Lifetime Warranty and exclusive Feel the Difference™ Guarantee.

Common Fits: Compatible with rear suspension on 1999-2004 Ford F-250 Super Duty, 1999-2004 Ford F-350 Super Duty, and 2005-2016 Ford F-350 Super Duty.
