Monroe Gas Magnum Shocks

Monroe Gas Magnum shocks are designed for vehicles that could use a little extra shock control. Whether you have a full size truck that constantly tows heavy loads, or a work van that carries a lot of extra weight around, Gas Magnum shocks can help with the harsher bounce of a heavier ride. These shocks have a larger diameter and a 2 inch reserve tube that holds more oil than OE shocks for better shock control and greater longevity of the shock itself.

Shocks for Heavy Duty Jobs

The heavy duty piston rod in the Gas Magnum is more durable than the rods in most original shocks and the seal is designed to self-lubricate resulting in less friction on the rod and longer effective lifespan of the shock. A nitrogen gas charge cuts down on harshness and shock fade and keeps the oil from foaming up when on a rough road which reduces the ability of the shock to control bumps and jolts to the vehicle. Gas Magnum shocks are covered by Monroe's limited lifetime warranty so you can rest assured that these shocks will get the job done over the long haul.
