Check Vehicle Fit

Monroe® OESpectrum® shock absorbers are engineered specifically for foreign nameplate vehicles and feature the latest global original equipment valving technologies. Developed through years of research and on-vehicle testing, Monroe® OESpectrum® units provide an unprecedented level of handling precision and control while filtering out the ride harshness commonly encountered on many foreign nameplate applications. This unique blend of control and comfort is made possible through Tenneco's 'Twin Technology Active Control System', an exclusive internal damping control technology first developed for leading global vehicle manufacturers. Tenneco's Twin Technology consists of its latest Impact Control Valve (ICV), which delivers exceptional control under virtually all driving conditions, and a patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.

Product Features:
  • All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
  • Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride
  • Fluon Banded Piston: The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability.
  • Twin Technology: Impact Control Valve (ICV), delivers exceptional control under virtually all driving conditions, and patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.
  • Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
  • Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.
  • 1-3/8 inch (34.9 mm) bore (On most applications)
  • 5/8-inch (15.9 mm) diameter piston rod (On most applications)

    Comments about Monroe OESpectrum Light Truck Shock Absorber:

    I replaced the OEM shocks in my Jeep Cherokee at 100,000 miles with another brand of shock. They were terrible -- no control over large bumps, but very harsh over small bumps. I took them off after a couple of weeks and replaced with Monroe Sensa-Tracs. The Sensa-Tracs ride smoothly, they provide excellent control over large and small bumps, and they have lasted well over 100,000 miles..

        This Monroe Sensa-Trac Light Truck Shock Absorber - Part No. 37029 has the potential energy that is stored as a force of motion within your suspension's spring as it cycles up and down, this energy in motion is called kinetic energy, we need to control this cycling by converting the kinetic energy into some other form, namely heat. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
