Tenneco Unveils Advanced Hydraulic Rebound Stop System for

• The highly adjustable Monroe® Ride Refine™ advanced HRS system improves peak load management, minimizes noise and promotes chassis lightweighting strategies.
• Fully hydraulic system now available in Monroe® OE Solutions twin tube shocks for BEV, other relatively heavy passenger vehicles

NORTHVILLE, Ill., June 17, 2024 (GLOBE NEWSWIRE) — Tenneco, a leading global supplier of passive and electronic shock absorbers for automotive applications, unveiled an innovative and highly adjustable Hydraulic Rebound Stop (HRS) system that minimizes shock absorber rebound. energy and noise encountered in BEVs and other relatively heavy passenger vehicles, ensuring optimal energy absorption. The new system, Monroe^® Ride Refine Advanced HRS also eliminates the need for commonly added chassis reinforcements to withstand high energy impacts. Now available in Monroe OE Solutions twin-tube shocks and struts, the system can also be customized to increase body control, allowing OEMs to deliver exceptional ride comfort in all driving situations.

Designed to provide high damping force and best-in-class sound performance, the Ride Refine™ Advanced HRS system features an innovative grooved and crimped pressure tube and high-strength seal ring that provide a virtually imperceptible transition and highly progressive towards HRS activation. The system’s wide adjustment curve is defined by the length of the pressure tube and bleeds to the seal ring side. By eliminating a mechanical spring, Tenneco engineers also reduced shock absorber weight and packaging requirements.

“This innovative system addresses a deep need among automakers to optimize the handling of peak suspension loads on electric vehicles, which are heavier and lower to the ground,” said Dan Keil, executive director of Tenneco, product engineering, Monroe Ride Solutions. “This versatile new technology delivers premium damping performance and an exceptionally wide adjustment range while minimizing weight and complexity as well as durability for long-lasting performance. This is precisely what BEVs, HEVs and vehicles with relatively high curb weights need.

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