About the Gas-Magnum Shock Absorber Line
The Monroe Gas-Magnum Shock Absorber line is designed to deliver consistent damping performance using pressurized nitrogen gas technology. This helps reduce shock fade and maintain vehicle control under various driving conditions. The 34909 model fits select Ford trucks and is built to meet the demands of both daily driving and heavier load applications.
Detailed Product Description
This Monroe 34909 shock absorber features a compressed length of 13.25 inches and a travel length of 8.75 inches, allowing for effective suspension movement and ride comfort. The extended length of 22 inches ensures proper fitment and stroke range. A metal dust shield protects the shock shaft from debris and corrosion, extending the service life of the component. The shock includes an extended bumper stop to prevent damage during full extension, while the absence of a compressed bumper stop allows for smooth compression travel. Both upper and lower mounts use a stem mount design with a 2.3/8" stem length and 3/8"-16 thread pitch, ensuring secure installation on compatible Ford trucks.
