Specifications

Keep drivers rested and tires wearing evenly with Monroe’s heavy-duty 66201 Gas-Magnum cab shock. A large 2-inch reserve tube carries extra all-weather fluid, so damping stays consistent from sub-zero dawn starts to desert afternoons. Precision multi-stage valving tames both compression and rebound forces, cutting steering shake and dashboard rattle. Factory LS77/LS34 loop-sleeve mounts line up with existing hardware—no spacers or drills needed. Every unit is pressure-tested, powder-coated against corrosion and backed by Monroe’s commercial-vehicle warranty for mile-after-mile confidence.
