1989 Ford F53 Rear Shock and Struts

The Monroe® Magnum RV shock absorber utilizes advanced technology, combining a gas charge and full displaced valving for superior RV performance.

Product Features:

• Robust hydraulic lock-out Prevents over-extension of the suspension, top-out of the piston and averts damage to the seal assembly
• PTFE coated bearing Reduces friction during operation between the rod and rod guide, improving durability
• Tenneco shouldered bushings Shouldered bushing and bonded bushing with sleeve designs prevent (bushing walkout) for improved quality and durability – on most applications
• Nitrogen gas-charged For improved ride and handling, helps maintain tire to road contact by reducing aeration – on most applications
• Loop welding technique Resistance weld with additional 360-degree weld to provide up to 15,000 lbs. (6,804 kg) tensile strength for maximum durability – when required
• 2-inch (50.8 mm) or 2-3/8-inch (60.3 mm) reserve tube The 2″ (555xx Series) or 2-3/8′ (557xx Series) reserve tube holds more fluid or more consistent performance – when required
• 1-3/8-inch (35 mm) or 1-3/4-inch (44.6 mm) bore The 1-3/8′ (555xx Series) or 1-3/4″ (557xx Series) bore is larger than most shocks to provide more efficient and consistent control – when required
• .05-inch Pressure tube withstanding pressure of 9KPSI
• All weather fluid Contains special modifiers to reduce frictions and ensure smooth rod reaction

The KYB Gas-a-just monotube truck shock absorber has additional performance advantages over the twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-Just is available as an OE monotube replacement and as an OE twin-tube performance upgrade. The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

Product Features:

• Adds Up To 25% More Damping Performance Over Original Equipment Shocks
• Components And Valving Designed Specifically For Heavy Duty Trucks
• Gas-A-Just Monotubes Include Additional Damping Over One Design For Vehicles That Work, Tow, And Have Larger, Heavier Tires & Wheels
• High Pressure Monotube Design Separates The Gas And Oil For Fade Free Operation And Instant Response
• Fluid Leaking Can Be A Cause Of Shock Failure, The KYB Gas-A-Just Has An Ultra-Smooth Triple Chrome Plated Chrome Piston Rod To Reduce Seal Wear
• The Higher Gas Pressure Of The KYB Gas-A-Just Responds Quickly To Improve Steering Response
• Electronic Safety Systems Depend On The Suspension, Brakes And Tires Operating As The Vehicle Manufacturer Intended. The KYB Gas-A-Just Helps Keep Electronic Safety Systems Performing As Designed.
