The Monroe Magnum shock absorber for Class 6-8 Vehicles is the first gas-charged, large-bore shock specifically designed for air spring and taper leaf suspensions. Its nitrogen gas charge provides the fast response essential for today's heavy truck suspension systems. Its extra-large piston bore is engineered to handle the demands of high mileage and severe use. When combined, the gas charge and large-bore provide the consistent control necessary for demanding truck suspensions Product Features:Robust hydraulic lock-out: Prevents over-extension of the suspension, top-out of the piston and averts damage to the seal assembly - when requiredPTFE coated bearing: Reduces friction during operation between the rod and rod guide, improving durability - on most applicationsTenneco shouldered bushings: Shouldered bushing and bonded bushing with sleeve designs prevent [bushing walkout] for improved quality and durability - on most applicationsNitrogen gas-charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applicationsLoop 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 required2-3/8 inch (60.3 mm) reserve tube: More fluid for more consistent performance - on most applications1-3/4-inch (44.6 mm) bore: Large bore than most shocks to provide more consistent control5/8-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, requir.05-inch Pressure tube withstanding pressure of 9KPSI10-stage valving: Reacts to wide range of driving conditions - on most applicationsAll weather fluid: Contains special modifiers to reduce frictions and ensure smooth rod reactionSingle-lip, low-friction oil seal
