Monroe Magnum RV 557004 Suspension Shock Absorber for Chevrolet P30

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

• 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
