Monroe 66112 Magnum Cab Suspension Shock Absorber

The Monroe Magnum Cab Suspension Shock Absorber (66112) is a gas-charged, heavy-duty cab shock engineered specifically for commercial vehicle cab suspension systems. It isolates the cab from the chassis to dramatically reduce road-induced noise, vibration, and harshness reaching the driver — delivering a smoother, more comfortable ride and reducing operator fatigue on long hauls.

Key Features:

• Patented Groove Tube Technology — Utilizes Monroe's proprietary grooved tube design paired with velocity-sensitive valving to deliver consistent, precise damping performance across varying road conditions
• Gas-Charged Design — Nitrogen gas charge helps maintain consistent ride quality, reduces aeration, and improves tire-to-road contact
• 10-Stage Valving — Tuned specifically to each application, adjusts to road extremes for exceptional handling and control
• Larger 1-3/8 in. Bore — Provides more efficient and consistent damping control on most applications
• Larger 2 in. Reserve Tube — Holds more fluid to improve performance and help dissipate heat under severe use conditions
• All-Weather Fluid — Special additives help maintain performance across extreme temperature ranges and reduce oil breakdown
• Shouldered & Bonded Bushing with Sleeve — Protects against bushing walkout for improved durability and long service life
• 360° Arc Welds — Full-perimeter welds provide maximum structural strength and durability
• Cab Isolation — Specifically designed for today's heavy-duty cab suspension systems to isolate the cab from frame-transmitted road shock

Backed by Monroe's Limited Commercial Warranty, the Magnum Cab 66112 is built to handle the demands of high-mileage, severe-duty commercial vehicles. Extended length: 11.00 in. Compressed length: 8.25 in. Travel: 2.75 in. Upper and lower mount codes: LS76/LS76.
