Front Shock Absorber for 1987-2024 Kenworth T800 & More - Monroe 66811

Smooth out the ride and rein in impact-related vibration on hardworking Class 3-6 trucks and buses with the Monroe Magnum Front Suspension Shock Absorber (MPN 66811). This gas-charged unit is a direct-fit replacement for the listed applications, fitting many Ford, Kenworth and Pierce Mfg. Inc. vehicles, among them the 1981-1997 Ford L9000 — see the "Vehicles it fits" section for the full list of applications.

• Gas-charged damping: A nitrogen gas charge helps reduce aeration and shock fade to maintain tire-to-road contact for a more consistent ride.
• Tuned control: 10-stage valving is tuned to each vehicle, and a larger 1-3/8 in. bore provides more efficient damping control on most applications.
• All-weather fluid: Special additives help handle extreme temperatures and reduce oil breakdown, while a 2 in. or 2-1/4 in. reserve tube holds more fluid where required.
• Built to endure: Shouldered and bonded bushings with a sleeve protect against bushing walkout, arc welds run up to 360°, and a PTFE-coated bearing plus nitrocarburized piston rod support longer service life on most applications.

A robust hydraulic lock-out helps prevent over-extension of air bags, piston top-out, and seal damage on most applications. If worn shocks are behind excessive vibration or poor ride control, these Magnum units help restore damping. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
