Monroe 34504 Shock Absorber - Front

Monroe Gas-Magnum 34504 Front Shock

Monroe Gas-Magnum shock absorber 34504 is built for front suspension use on midsize and full-size trucks and vans that need firm control without an overly harsh ride. It is a direct-fit suspension shock absorber for heavy-duty Chevrolet Silverado and GMC Sierra applications, including select Suburban 2500 and Yukon XL 2500 models.

The Gas-Magnum line is Monroe’s heavy-duty shock absorber family, using increased fluid capacity to manage heat and damping demand more efficiently than a standard 1-inch bore design. That makes this Monroe 34504 a practical choice for front-end control on larger vehicles that see towing, hauling, or daily road use.

Confirm the upper stem mount and lower loop bushing and sleeve mount dimensions against the original shock absorber before installation.
