Monroe OESpectrum shocks and struts

OESpectrum Shocks & Struts

Monroe® OESpectrum® shocks and struts are designed with the right technology specific to each vehicle’s ride and handling profile to filter out noise, vibration and harshness while enhancing drivability and performance. Covering the spectrum of import and domestic vehicles, OESpectrum is built different.

Designed with the Right Technology for Improved Control

Monroe OESpectrum shocks and struts for cars, light trucks and SUVs provide an exceptional level of handling precision and control while filtering out noise, vibration and harshness.

Built to Last

Self-lubricating fluid seal retains gas and reduces excessive friction against the piston rod to help reduce premature wear.

Exceptional Handling

Tuned specifically for each application, full displaced rod valving automatically adjusts to road extremes while the larger bore provides more efficient damping control to provide consistency and a smooth ride.

Control & Durability

PTFE-banded piston provides consistent sealing between piston and pressure tube for better control and increased durability.

Features & Benefits

Improves Performance

Nitrogen gas charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade.

Consistent Ride

OE all-weather fluid contains special additives to assist with extreme temperatures and helps reduce oil breakdown.

Reduces Noise, Vibration and Harshness

Innovative, vehicle-specific technologies deliver improved control under most driving conditions while isolating impact-related noise, vibration and harshness.
