Monroe 66196 Magnum Cab Gas-Charged Heavy-Duty Shock Absorber

The Monroe Magnum Cab Shock Absorber (66196) is a gas-charged, heavy-duty cab suspension shock engineered specifically for commercial vehicles with cab suspension systems. It effectively isolates the cab from the chassis to minimize road-induced noise, vibration, and harshness (NVH), delivering a smoother, more comfortable ride and reducing driver fatigue on long hauls.

Featuring Monroe's patented groove tube technology and velocity-sensitive valving, this shock sets a new industry standard for driver comfort in heavy-duty cab suspension applications. The nitrogen gas charge reduces aeration and shock fade, maintaining consistent tire-to-road contact for improved ride and handling.

Key Features:

• 10-Stage Valving: Tuned specifically to each vehicle, automatically adjusts to road extremes for precise, controlled response
• 1-3/8 in. Bore: Larger bore provides more efficient and consistent damping control (most applications)
• 2 in. Reserve Tube: Holds more all-weather fluid with special additives to resist extreme temperatures and reduce oil breakdown
• Nitrogen Gas-Charged: Reduces aeration and shock fade for improved ride and handling performance
• PTFE-Coated Bearing: Reduces friction between rod and rod guide for longer service life (most applications)
• Nitrocarburized Piston Rod: Provides enhanced durability and extended service life
• Shouldered & Bonded Bushing with Sleeve: Protects against bushing walkout for improved quality and longevity
• 360° Arc Welds: Full perimeter welds ensure maximum structural durability
• Internal Rebound Bumper: Protects against over-extension for added reliability
• Metal Dust Shield: Shields internal components from road debris and contamination
