ACE High-Pressure Pipe - Rear Lower within the Active Cornering Enhancement hydraulic circuit.

This pipe carries hydraulic pressure from the ACE valve block to the rear anti-roll bar actuator, routed along the lower chassis path at the rear of the vehicle. The ACE system applies controlled torque to the anti-roll bars via hydraulic actuators to counteract body roll during cornering - this pipe is part of the high-pressure delivery side of the circuit that actuates the rear anti-roll bar.

Frequently asked questions

What is the RQB000390 ACE pipe for?
The RQB000390 is a high-pressure hydraulic pipe in the Active Cornering Enhancement (ACE) system, carrying pressure from the ACE valve block to the rear anti-roll bar actuator. It fits the Land Rover Discovery 2 (1998-2004) and routes along the lower rear chassis.
Where does this ACE pipe sit on a Discovery 2?
This ACE pipe runs along the lower chassis at the rear of the Discovery 2 (1998-2004), between the ACE valve block and the rear anti-roll bar actuator. It's on the high-pressure delivery side of the hydraulic circuit that controls body roll during cornering.
Why do ACE pipes fail on the Discovery 2?
ACE pipes on the Discovery 2 typically fail through corrosion of the steel pipe or leaks at the unions, since they run exposed along the underside. Signs include ACE warning messages, hydraulic fluid leaks, or increased body roll. A leaking high-pressure pipe should be replaced to restore the system.
