Tenneco's Monroe Ride Solutions introduced an integrated main and secondary valve system for passive dampers, and Monroe OE Solutions double-tube dampers now feature the new design. The system combines the Monroe DCx piston valve, introduced earlier this year, with the Monroe Ride Refine RC1 secondary valve.

Why it matters

The integrated system is designed to remove the longstanding compromise between ride comfort and control when driving conditions vary. Multiple automotive OEMs have already selected the DCx piston valve for upcoming models.

The DCx valve uses dual-stage bleed technology that is independently tunable in rebound and compression, while the RC1 valve reduces rebound-mode damping force during high-frequency wheel motions. No quantitative performance figures were disclosed.

The players

Monroe Ride Solutions

The Tenneco business unit that develops electronic and passive suspension systems for light vehicles, commercial trucks and off-highway equipment, and that introduced the integrated valve system.

The details

A bypass within the DCx valve directs oil into the RC1 valve when a vehicle encounters a rough road surface, while the dual-stage bleed design generates minimal damping forces at very low piston rod velocities. Monroe Ride Solutions develops electronic and passive suspension systems for light vehicles, commercial trucks and off-highway equipment.

Timeline

  1. Earlier in 2026: Monroe DCx piston valve introduced.

  2. November 5, 2026: Integrated valve system introduced.

Roadmap

The integrated system builds directly on the Monroe DCx piston valve introduced earlier in 2026, extending that valve's dual-stage design with the RC1 secondary valve. It reflects a broader push in passive suspension toward components that adapt damping across varied road conditions without electronic control.

Drivers of vehicles equipped with these dampers could see ride comfort and handling control handled by one integrated valve instead of a tradeoff between them. The benefit will depend on which automakers adopt the system in their production models.

The takeaway

Passive suspension improvements such as this integrated valve can deliver better ride control without adding electronic complexity. Buyers comparing vehicles may find damper design a useful factor when evaluating ride quality.
