Monroe Shocks & Struts Magnum RV 557001 Shock Absorber

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 36-degree weld to provide up to 15, lbs. (6,84 kg) tensile strength for maximum durability - when required
• 2-inch (5.8 mm) or 2-3/8-inch (6.3 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
• 5/8-inch (16 mm) diameter piston rod: Nitrocarburized design more environmentally friendly, maintaining chrome structural benefits, without affecting durability or use life of the rod. Sintered iron design allows for more precise piston dimensions, requiring no additional components for exceptional fit - on most applications
• .5-inch Pressure tube withstanding pressure of 9KPSI
• All weather fluid: Contains special modifiers to reduce frictions and ensure smooth rod reaction
