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 l Product Features:Robust hydraulic lock-out Prevents over-extension of the suspension, top-out of the piston and averts damage to the seal assembly - on most applicationsPTFE 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 provide up to 13,100 lbs.
