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.

Common Applications and Problem Solving

  • Reduces excessive body roll and sway during towing or hauling
  • Improves ride comfort over rough or uneven terrain
  • Restores suspension control after wear or damage to original shocks
  • Minimizes bottoming out and harsh impacts on heavy loads
  • Enhances vehicle stability and handling in off-road or worksite environments

Installation Notes and Tips

Ensure compatibility with Ford F-250 Super Duty and F-350 Super Duty models before installation. Verify mounting hardware dimensions match the vehicle’s suspension points, particularly the loop bushing and sleeve mounts. It is recommended to replace shocks in pairs to maintain balanced suspension performance. Proper torque specifications should be followed to secure the shock absorber without damaging bushings or mounts.
