Gabriel Shock Absorber - Freightliner Cascadia 126 & Western Star 49X - 83911 18-73207-000 A83911

Take the bounce out of a late-model Freightliner or Western Star with this Gabriel Heavy-Duty Shock Absorber distributed by FleetPro Parts & Tires. It is the direct replacement for Freightliner 18-73207-000 on the Cascadia 126 Day Cab 2021-2024 and on Western Star 49X 2021-2024 and 57X Day Cab 2023-2024. A weak or leaking shock stops controlling the axle after each bump, and the truck tells you about it: the cab bounces, the tread starts cupping, and every bushing and mount on that corner works harder than it should. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Bounce Under Control: The Gabriel 83911 Advantage

A shock is the only thing turning suspension motion into heat instead of more motion. When it can no longer do that, the spring or air bag keeps cycling on its own and the tire spends part of every oscillation not fully loaded — which is exactly how a tread ends up scalloped and noisy. Putting a fresh unit on settles the chassis in one stroke, quiets the ride, and protects a set of tires worth many times the price of the shock.

At FleetPro Parts & Tires we know these late Cascadia and Western Star jobs come in as a pair of numbers, so we stock the Gabriel unit that covers them. This shock is a direct replacement for highly searched industry numbers including Freightliner 18-73207-000, listed as 1873207000 and 814903018451, and Gabriel 83911. Replace shocks in pairs on the same axle so damping stays even side to side.
