Front Shock Absorber for 2011-2012 International Terrastar - Monroe 66446

Help keep a hardworking commercial truck riding steady with the Monroe Magnum 66446 front suspension shock absorber, built for high-mileage, severe-use class 3-6 trucks and buses. It fits the 2011-2012 International Terrastar. The gas-charged design is intended to give quicker response and a stable, more comfortable ride. Replacing worn-out units with Magnum shocks helps reduce excessive vibration.

• Consistent ride: All-weather fluid carries special additives that help it cope with extreme temperatures and reduce oil breakdown. A 2-in. or 2-1/4-in. reserve tube holds more fluid to improve performance (when required).
• Handling: 10-stage valving, tuned specifically to each vehicle, adjusts to road extremes. A larger 1-3/8-in. bore provides more efficient damping control for a consistent, smooth ride (most applications).
• Strong and durable: A shouldered bushing and a bonded bushing with sleeve help protect against bushing walkout. Arc welds reach up to 360° for durability.
• Built to last: A hydraulic lock-out is designed to prevent over-extension of air bags and top-out of the piston. It also helps avert damage to the seal assembly (on most applications).

The nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade. The shock is also designed to isolate impact-related noise, vibration and harshness under most driving conditions. On most applications, a PTFE-coated bearing reduces friction between the rod and rod guide. A nitrocarburized piston rod adds durability for a longer service life. Monroe backs it with its 90-day Risk Free Ride Offer and Limited Commercial Warranty. See the "Vehicles it fits" section for complete fitment details.
