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 Ford full-size vans and wagons, the Gas-Magnum delivers reliable rear suspension performance for E-Series Econoline platforms across multiple model years with consistent, controlled damping.

• 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 1992-2024 Ford E-250 and E-350 Econoline, 2003-2024 Ford E-450 Super Duty, 1999-2024 Ford E-350 Super Duty, 1996-1999 Ford Econoline Super Duty, and 1999-2002 Ford E-450 Econoline Super Duty.
