Monroe® OESpectrum® shocks feature the revolutionary, patented
M-RTECH®2 Rebound Valving Technology™, which provides virtually instantaneous feedback and response to changing driving conditions for exceptional road-holding capability, a smoother ride and increased driver control and confidence. This technology is combined with Tenneco’s new high-speed Impact Control Valve. This, in turn, helps each OESpectrum unit deliver a unique blend of world-class control and reduced noise, vibration and harshness.
