Monroe Shocks & Struts Suspension Shock Absorber P/N:550057
Keep hardworking commercial miles under control with the Monroe Magnum Rear Suspension Shock Absorber 66454. This gas-charged rear shock is a direct-fit replacement for many class 3-6 Hino and Lion trucks and buses, among them the 2021-2023 Hino XL7, 2021-2022 Lion LION6 and 2021-2022 Lion LION8 — see the "Vehicles it fits" section for the full list.
A robust hydraulic lock-out prevents over-extension of the air bags, piston top-out and damage to the seal assembly on most applications, and the design isolates impact-related noise, vibration and harshness under most driving conditions. For balanced ride control, replace the rear shocks as a pair. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
