Tenneco, a leading provider of passive and electronic dampers for automotive applications, has introduced the innovative Monroe® Ride Refine Advanced Hydraulic Rebound Stop (HRS) system. This tunable system reduces damper rebound energy and noise in BEVs and other heavy passenger vehicles, ensuring optimal energy absorption. It also eliminates the need for additional chassis reinforcements for high-energy impacts. Now available in Monroe OE Solutions double-tube shock absorbers and struts, the HRS system can be custom-tuned to enhance body control, allowing OEMs to deliver exceptional ride comfort in all driving conditions.

Engineered to provide high damping force and best-in-class noise performance, the Ride Refine™ Advanced HRS system features an innovative grooved and swaged pressure tube and high-resistance sealing ring that provide a virtually imperceptible, highly progressive transition to HRS activation. The system’s broad tuning curve is defined by the pressure tube swage length and bleeds on the side of the sealing ring. By eliminating a mechanical spring, Tenneco engineers also reduced damper weight and packaging requirements.

“This innovative system addresses a profound need among vehicle OEMs to optimize management of peak suspension loads on electric vehicles, which are heavier and sit lower to the ground,” said Dan Keil, Tenneco Executive Director, Product Engineering, Monroe Ride Solutions. “This versatile new technology delivers premium damping performance and an exceptionally broad tuning range while minimizing weight and complexity as well as durability for long lasting performance. It is precisely what is needed for BEVs, HEVs and vehicles with comparatively high curb weight.”

With the introduction of the new system, Tenneco now offers three highly effective, differentiated hydraulic stop technologies covering virtually all passenger vehicle use cases. Other Monroe designs include spring equipped standard HRS and Performance HRS. For more information on Monroe OE Solutions visit: oe-monroe.com.
