Monroe Shocks & Struts 557045 Product Description

Monroe Magnum RV 557045 Amortisseur

Key Features

  • Robusto bloqueo hidráulico: Evita la extensión excesiva de la suspensión, el tope del pistón y evita daños en el conjunto del retén.
  • Cojinete recubierto de PTFE: Reduce la fricción durante el funcionamiento entre la barra y la guía de la barra, mejorando la durabilidad
  • Bujes con rebordes Tenneco: Bujes con rebordes y bujes adheridos con diseños de manguito que evitan la salida del buje para mejorar la calidad y la durabilidad, en la mayoría de las aplicaciones
  • Cargado con gas nitrógeno: Para una mejor conducción y manejo, ayuda a mantener el contacto de la llanta con el suelo al reducir la aireación - en la mayoría de las aplicaciones
  • Técnica de soldadura en bucle: Soldadura por resistencia con soldadura adicional de 360 ​​grados para proporcionar hasta 15,000 libras (6.804 kg)de resistencia a la tracción para una máxima durabilidad (cuando sea necesario)
  • Tubo de reserva de 2 pulgadas (50,8 mm) o 2-3/8 pulgadas (60,3 mm): El tubo de reserva de 2" (Serie 555xx) o 2-3/8' (Serie 557xx) retiene más fluido o un rendimiento más consistente - cuando sea necesario
  • El diámetro interior de 1-3 / 8'' (Serie 555xx) o 1-3 / 4'' (Serie 557xx) es mayor que la mayoría de los amortiguadores para proporcionar un control más eficiente y consistente, cuando sea necesario
  • Vástago de pistón de 5/8'' (16 mm) de diámetro: Diseño nitrocarburado ecológico, mantiene los beneficios del cromo, sin afectar la durabilidad. El uso de hierro sinterizado permite dimensiones de pistón precisas para un ajuste excepcional
  • Tubo de presión de .05 pulgadas que soporta una presión de 9 KPSI
  • Fluido para todo clima: Contiene modificadores especiales para reducir la fricción y asegurar una reacción suave de la barra.
  • FOR RECREATIONAL VEHICLES -- Designed to handle the demands of recreational vehicles that go on cross country adventures and trips close to home
  • CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while larger reserve tube holds more fluid to improve performance (when required)
  • EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the bore provides more efficient and consistent control (most applications)
  • STRONG AND DURABLE -- Shouldered bushing and bonded bushing with sleeve protects from bushing walkout for improved quality; arc welds up to 360° for durability
  • BUILT TO LAST -- Robust hydraulic lock-out prevents over extension of air bags, top-out of the piston and averts damage to seal assembly (when required)
  • REDUCED NOISE, VIBRATION AND HARSHNESS -- Delivers exceptional control and isolates impact-related noise, vibration and harshness under most driving conditions
  • IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
  • BUY WITH CONFIDENCE -- Comes with Monroe’s 90-day Risk Free Ride Offer and Limited Commercial Warranty

El amortiguador Monroe® Magnum ™ RV utiliza tecnología avanzada, que combina una carga de gas y válvulas completamente desplazadas para un rendimiento superior de su casa rodante.

  • Direct fit, no surprises
    Marc D.Verified BuyerMay 28, 2026

    Lined up perfectly with the original. Install took about an hour with the right press. Solid feel back in the steering, no more clunk over bumps.

  • Shipped fast across Canada
    Jen P.Verified BuyerMay 14, 2026

    Ordered on a Monday, had it by Wednesday in Calgary. Greasable fitting is a nice touch. Quality looks on par with OEM.

  • Good part, double-check your side
    Steve R.Verified BuyerApr 30, 2026

    Works great so far. Just confirm fitment for your exact trim before ordering — the fitment list on the page was accurate for mine.

  • Quiet again
    Amrit S.Verified BuyerApr 19, 2026

    Replaced both sides at the same time. The knocking noise is completely gone. Boot quality feels durable.
