Monroe Shocks & Struts Magnum 66638 Shock Absorber

The Monroe® Magnum™ shock absorber for class 3-6 Vehicles is gas-charged for quicker response and a stable, more comfortable ride. Replacing worn-out units with hard-working Magnum™ shocks can help reduce excessive vibration. The result can be better tire life, less downtime and a lower cost per mile.

• Robust hydraulic lock-out: Prevents over-extension of the suspension, top-out of the piston and averts damage to the seal assembly - on most applications
• PTFE coated bearing: Reduces friction during operation between the rod and rod guide, improving durability - on most applications
• 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 provide up to 13,1 lbs. (6,395 kg) tensile strength for maximum durability - when required
• 2-inch (5.8 mm) or 2-1/4-inch (57.2 mm) reserve tube: More fluid for more consistent performance - when required
• 1-3/8-inch (35 mm) bore: Larger bore than most shocks to provide more efficient and consistent control - on most applications
• 5/8-inch (16 mm) diameter nitrocarburized 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
• 1-stage valving: Reacts to wide range of driving conditions - on most applications
