Monroe 34756 Shock Absorber - Rear

Monroe Gas-Magnum Shock Absorber 34756

Monroe Gas-Magnum Shock Absorber 34756 is built for rear suspension control on midsize and full-size trucks and vans. It delivers firm damping without creating a harsh ride, making it a practical choice for heavy-duty street use and load-carrying applications.

The Gas-Magnum line is Monroe’s truck and van shock family, engineered with greater fluid capacity than standard 1-inch bore shocks so the unit can manage heat and motion more efficiently. For Chevrolet Express 3500, GMC Savana 3500, Chevrolet C3500, GMC C3500, and Chevrolet C35 rear suspension service, this design supports consistent control under demanding conditions.
