Keep your hardworking class 3-6 truck riding firm and controlled with the Monroe Magnum Front Suspension Shock Absorber 66602. This gas-charged front shock installs as a direct-fit replacement for many commercial vehicles, among them the 1995-1998 UD 1800, 1998-2013 UD 2000 and 2005-2013 UD 2300DH — see the "Vehicles it fits" section for the full list.
Built for the demands of high-mileage and severe-use trucks and buses, it swaps in for worn-out units to help reduce excessive vibration.
- Gas-charged: nitrogen charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
- All-weather fluid: special additives assist with extreme temperatures and help reduce oil breakdown; a 2-in. or 2-1/4-in. reserve tube holds more fluid (when required).
- 10-stage valving: tuned to the vehicle to adjust to road extremes, with a larger 1-3/8-in. bore for efficient damping control (most applications).
- Strong and durable: shouldered and bonded bushing with sleeve protects against bushing walkout, with arc welds up to 360°.
A PTFE-coated bearing reduces friction between the rod and rod guide, and on most applications a hydraulic lock-out prevents over-extension. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
