Detailed Product Description
This Monroe Magnum Light Truck Shock Absorber 550065 is designed to meet the suspension needs of Ford F-250 Super Duty and F-350 Super Duty trucks. The shock absorber features a compressed length of 16.5 inches and an extended length of 27.17 inches, providing a travel length of 10.67 inches to accommodate heavy-duty suspension travel. The inclusion of a dust shield helps protect internal components from dirt and debris, extending the service life of the shock. An extended bumper stop is incorporated to enhance durability during suspension compression, while the absence of a compressed bumper stop and extended hydraulic lockout indicates a focus on consistent damping performance without additional mechanical stops. The lower mounting uses a loop bushing and sleeve mount with precise dimensions (9/16" sleeve ID x 1.5" sleeve OAL), and the upper mounting features a loop bushing mount (5/8" bushing ID x 1.3125" bushing OAL), ensuring secure and proper fitment on compatible vehicles.
The Magnum Light Truck Shock Absorber line by Monroe is tailored for heavy-duty trucks requiring robust suspension components. This product line emphasizes durability and consistent performance under load, making it suitable for trucks like the Ford F-250 and F-350 Super Duty models that often encounter demanding driving conditions.
