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, including the 1973-1979 Ford F-700, 1981-1997 Ford L9000, 1981-1997 Ford LT9000, 1987-2024 Kenworth T800, 1982-2016 Kenworth W900, and 2004-2009 Pierce Mfg. Inc. Dash — see the Buyer's Guide tab for the full list of Ford and Kenworth 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.
Is this a front shock absorber?
Yes. The Monroe Magnum 66811 is cataloged as a front suspension shock absorber for the listed Class 3-6 truck and bus applications.
What vehicles does it fit?
It's a direct-fit replacement for many Ford (F-700, L9000, LT9000) and Kenworth (T800, W900, T600A) trucks, plus the Pierce Dash. See the Buyer's Guide tab for the full year and model list.
Is this shock gas-charged?
Yes. It uses a nitrogen gas charge designed to reduce aeration and shock fade, helping maintain tire-to-road contact for more consistent damping.
How many should I order?
Shocks are sold individually. Replacing both sides on an axle together as a matched pair is recommended for balanced ride and handling.
What are signs my shocks may need replacing?
Excessive vibration, bouncing, or poor ride control can be signs of worn shocks. Have the suspension inspected first, since these symptoms can have other causes.
