Product Details

The Monroe® Gas-Magnum™ RV shock absorber line is engineered specifically for the unique and demanding requirements of recreational vehicle applications. Combining nitrogen gas-charging with full displaced valving technology, these shocks deliver superior ride control and handling stability for motorhomes, tow vehicles, and trailers — covering a broad range of RV platforms including Class A, B, and C motorhomes.

Designed to exceed the demanding standards of original equipment manufacturers, the Gas-Magnum RV line effectively reduces the bounce and wander associated with RV and trailer travel, while also minimizing the surge caused by trailer motion feedback to the tow vehicle — resulting in a smoother, more comfortable, and more controlled driving experience across a wide variety of road conditions.

Key Features:

  • Nitrogen gas-charged design — helps maintain consistent tire-to-road contact by reducing aeration and shock fade, improving overall ride and handling
  • Full displaced valving — delivers optimized performance across both compression and extension cycles for smooth, controlled damping
  • Larger-bore piston design — provides more efficient and consistent damping control compared to conventional shock absorbers, with greater fluid capacity for extended service life
  • Sintered iron piston — allows for greater dimensional precision, requiring no additional components for an exceptional fit and enhanced durability
  • Heavy-duty nitrocarburized piston rod — an environmentally friendly alternative to chrome that maintains structural integrity and corrosion resistance throughout the life of the shock
  • Robust hydraulic rebound lockout — prevents over-extension of the suspension, protects the piston from topping out, and guards the seal assembly from damage
  • PTFE-coated bearing — reduces friction between the rod and rod guide during operation for smoother, longer-lasting performance
  • Tenneco shouldered bushings — resist bushing walkout for improved quality and extended service life
  • All-weather fluid formulation — special modifiers reduce friction and ensure consistent, smooth rod reaction across a wide range of driving conditions and temperatures
  • Self-lubricating fluid seal — retains gas charge without excessive friction or wear on the piston rod
  • Heavy-duty pressure tube — engineered to withstand high internal pressures to handle the severe road conditions common in RV travel

Backed by Monroe's decades of ride control engineering expertise, the Gas-Magnum RV series is covered by a 2-year/200,000-mile limited commercial warranty against defects and wear-out — a trusted solution for restoring or enhancing suspension performance across a wide variety of recreational vehicle applications.

Hope these work!

The sticker, on the side of the shipping box, had the complete shipping address but the mailing label was incomplete. I had to go to the post office, with the tracking number, and they had to search for it.

no problems with the order.

parts were easy to find

So far so good

Smooth transaction.

thanx
