SKU:
MON66178MM

Description:

The Monroe® Magnum® Cab Suspension Shock Absorber is a gas-charged unit designed for heavy-duty cab suspensions. It isolates the cab from the frame for a smoother, more comfortable ride and utilizes velocity-sensitive valving to deliver a new standard in driver comfort (most applications).

Engineered for a wide range of heavy-duty cab suspension applications, the Magnum Cab shock delivers consistent cab isolation on Peterbilt, Kenworth, International, Freightliner, Mack, Ford, and other commercial platforms.

  • FOR HARDWORKING COMMERCIAL VEHICLES: Designed to handle high mileage and severe use vehicles with cab suspensions.
  • CONSISTENT RIDE: All-weather fluid handles extreme temperatures; larger 2-in. reserve tube holds more fluid (when required).
  • EXCEPTIONAL HANDLING: 10-Stage valving tuned to each vehicle; larger 1-3/8-in. bore for efficient, consistent control (most applications).
  • STRONG AND DURABLE: Shouldered and bonded bushings with sleeve; arc welds up to 360° for durability.
  • LONGER SERVICE LIFE: PTFE-coated bearing and nitrocarburized piston rod for durability and long service life (most applications).
  • REDUCED NOISE, VIBRATION AND HARSHNESS: Isolates impact-related NVH under most driving conditions.
  • IMPROVES PERFORMANCE: Nitrogen gas-charge reduces aeration and shock fade.
  • BUY WITH CONFIDENCE: Comes with Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

Common Fits: Compatible with cab suspension on Peterbilt 357, 375, 376, 377, 378, and 379 (1986-2008), Kenworth W900, T400, and T800 (1982-2024), International 4600, 4700, 4800, and 4900 (1990-2003), Freightliner FLC112 and FLD112 (1985-2007), Mack MR (1981-2007), and 1991-1997 Ford LA8000F.
