Keep hardworking commercial trucks and buses riding smoothly with the Monroe Magnum Front Suspension Shock Absorber (MPN 66422). This gas-charged front shock is a direct-fit replacement for class 3-6 vehicles, including the 2002-2008 and 2016-2019 International 4300, 1996-2002 International 3000, 2002-2011 International 3200, 2010-2024 IC Corporation CE School Bus and 2014-2024 Nexus Ghost — see the Buyer's Guide tab for the full list of applications.
- Gas-charged control: A nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade for more consistent ride and handling.
- Built for commercial duty: Designed to handle the demands of high-mileage, severe-use class 3-6 trucks and buses, helping to reduce excessive vibration.
- 10-stage valving: Tuned to each vehicle to adjust to road extremes, while a larger 1-3/8-in. bore provides more efficient damping control on most applications.
- All-weather fluid & durable build: Special additives help handle extreme temperatures and reduce oil breakdown, a 2-in. or 2-1/4-in. reserve tube holds more fluid where required, and shouldered and bonded bushings with sleeve help protect against bushing walkout, with arc welds up to 360°.
A robust hydraulic lock-out helps prevent over-extension and piston top-out on most applications, and a PTFE-coated bearing paired with a nitrocarburized piston rod supports longer service life. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
