Key Features

  • Robusto bloqueo hidráulico: Evita la extensión excesiva de la suspensión, el tope del pistón y evita daños en el conjunto del retén (en la mayoria de aplicaciones)
  • Cojinete recubierto de PTFE: Reduce la fricción durante el funcionamiento entre la barra y la guía de la barra, mejorando la durabilidad - en la mayoria de aplicaciones
  • 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
  • Técnica de soldadura en bucle:La soldadura por resistencia con soldadura adicional de 360 ​​grados proporciona hasta 12,100 libras (5488 kg) de resistencia a la tracción para una máxima durabilidad (cuando se requiera)
  • Tubo de reserva de 2 pulgadas (50,8 mm): Más fluido para un rendimiento más uniforme - en la mayoría de las aplicaciones
  • Diámetro de 1-3/8 pulgadas (35 mm): Diámetro más grande que la mayoría de los amortiguadores para brindar un control más eficiente y consistente, en la mayoría de las aplicaciones
  • 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

  • LONGER SERVICE LIFE -- Bearing with PTFE coating reduces friction between rod and rod guide combined with nitrocarburized piston rod provides durability and longer service life (most applications)
  • 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

    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.

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

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