Why Buy Monroe Gas-Magnum Truck Shock Absorbers?

The Monroe® Gas-Magnum® truck shock absorber is designed for mid to full size, hard working pick-up trucks and vans. These units provide firm control without a harsh ride. With up to twice the fluid capacity of standard 1" bore shocks, Monroe Gas-Magnum truck shocks work more efficiently with less effort.

The result: enhanced control with uncompromised ride comfort.

  1. All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  2. Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride comfort.
  3. Sintered Iron Piston: Stronger than traditional metals, enhances durability for longer service life.
  4. Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration.
  5. 2" Reserve Tube: More fluid for more consistent performance.
  6. 1-3/8" Bore: Lower operating pressure than standard 1" bore units.
  7. 5/8" Piston Rod: Heavy-duty nitrocarburized rod* for long service life.
  8. Special Seal: "Self-lubricating" fluid seal designed to retain gas without excessive wear or friction.
