Detailed Description

Monroe 550067 is part of the Magnum Light Truck Shock Absorber line and is engineered for emergency, municipal fleet, and construction-duty environments. The shock uses a larger bore and reinforced mounting points to handle repeated load changes while maintaining controlled suspension movement. With a compressed length of 14.25 inches, an extended length of 22.67 inches, and 8.42 inches of travel, it is built for applications that require substantial suspension articulation. This part cross-references KYB 344077 for the same application.

Compatible with Ford F-350 Super Duty rear suspension applications, this Monroe shock absorber is a direct fit for 2017-2026 Ford F-350 Super Duty, rear. The Monroe 550067 is a practical replacement choice when restoring damping control on a heavy-duty truck that sees frequent towing, hauling, or fleet use.

What It Is Used For

  • Restoring rear suspension control after shock wear.
  • Reducing excessive bounce and body movement.
  • Improving stability under heavy load conditions.
  • Addressing uneven ride quality from fatigued dampers.
  • Replacing a worn shock on Ford F-350 Super Duty rear applications.

Installation Notes and Tips

Verify compressed length, extended length, and mounting style before installation. This shock uses a loop bushing upper mount and a loop bushing and sleeve lower mount, so confirm the sleeve dimensions match the vehicle application. Inspect surrounding suspension components for wear before replacing the shock absorber.

Quality Assurance

Monroe Severe Service Ride Control products are engineered for demanding fleet and work-truck use, with strengthened components and arc-welded mounts for added durability.
