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 full-size Chevrolet and GMC C/K trucks, the Gas-Magnum delivers reliable rear suspension performance across multiple model years and configurations with a consistent, controlled ride.

• 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 1988-2000 Chevrolet and GMC C1500, C2500, C3500, K1500, K2500, and K3500, and 1988-1990 Chevrolet C35.
