Monroe Gas-Magnum Shocks
Monroe Gas-Magnum shocks provide firm control without a harsh ride by using up to twice the fluid capacity of standard 1 in. bore shocks. This all-weather fluid contains special modifiers to reduce friction and ensure smooth rod reaction. The shocks also feature full displaced valving for better range on both the compression and extension cycles, ensuring a comfortable ride. These shocks use a sintered iron piston, which is stronger than traditional metals, to enhance durability for longer service life. Each unit is nitrogen gas-charged for improved ride and handling; reduced aeration helps to maintain tire-to-road contact. Their large 2 in. reserve tube allows for more fluid-producing consistent performance, while their 1 3/8 in. bore offers more lowering pressure than conventional 1 in. bore shocks. Monroe Gas-Magnum shocks are finished off with a 5/8 in. heavy-duty nitrocarburized rod and a special self-lubricating fluid seal to retain gas without excessive wear or friction.
