Shock Absorber for 2019-2025 Mack Pinnacle & More - Monroe 66886

Keep hardworking commercial trucks riding under control with the Monroe Magnum Suspension Shock Absorber 66886, a gas-charged unit built for the demands of high-mileage and severe-use Class 3-6 trucks and buses. It's cataloged for the front and rear positions and drops in as a direct-fit replacement across a long commercial list, including the 1973-1980 Chevrolet C60, the 1989-1999 International 9300, and the 1987-2020 Kenworth T800 — see the "Vehicles it fits" section for the full list of applications (Chevrolet, International, Kenworth, Mack and Workhorse).

• Gas-charged design: a nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
• 10-Stage valving: tuned to the vehicle and paired with a larger 1-3/8-in. bore to help provide efficient damping control and a smooth, consistent ride (most applications).
• All-weather fluid: special additives assist with extreme temperatures and help reduce oil breakdown, while a 2-in. or 2-1/4-in. reserve tube holds more fluid to help improve performance (when required).
• Strong and durable: shouldered and bonded bushing with sleeve helps protect from bushing walkout, with arc welds up to 360° for durability.

Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
