Description

Control ride motion and keep heavy loads planted with the Monroe Magnum Rear Suspension Shock Absorber 65404, a gas-charged, large-bore shock built for the demands of class 6-8 trucks and buses. It installs in the rear position on many hardworking commercial vehicles, including the 1987-2024 Kenworth T800 and 1981-2024 Kenworth W900 — see the "Vehicles it fits" section for the full list.

Nitrogen gas-charged: The gas charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
10-stage valving: Tuned to the vehicle, with a larger 1-3/4-in. bore for more efficient damping control and a smooth, consistent ride (most applications).
All-weather fluid: Contains additives to help handle temperature extremes and reduce oil breakdown, while a larger 2-3/8-in. reserve tube holds more fluid (most applications).
Strong and durable: Shouldered bushing and bonded bushing with sleeve protect against bushing walkout, with arc welds up to 360° for durability.

A robust hydraulic lock-out helps prevent over-extension of the air bags and piston top-out (most applications), and a PTFE-coated bearing with a nitrocarburized piston rod reduces friction for longer service life. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
