Product Information

MONROE GAS-MAGNUM SHOCK ABSORBER

Get back in firm control and maintain a smoother ride with the enhanced strength and precision-engineered design of Monroe’s Gas-Magnum shock absorber. Founded in 1916, Monroe manufactures top-quality OE replacement shock absorbers, struts and mounts for the automotive aftermarket.

  • Full displaced valving maintains optimum ride control and comfort
  • Piston built with sintered iron for enhanced strength
  • 5/8-inch nitrocarburized piston rod engineered to provide extended lifespan
  • Nitrogen gas charging facilitates ideal tire-to-road contact by diminishing aeration
  • Increased size of 2-inch reserve tube accommodates more fluid for steadier performance
  • All-weather fluid reduces friction and maintains dependable rod reaction
  • Gas tightly retained by self-lubricating fluid seal
  • 1 3/8-inch bore enables shock to operate at lower pressure
