Description
This Discovery 2 ACE actuator ram is the hydraulic ram used by the Active Cornering Enhancement system to act on the anti-roll bar and control body roll. The ACE system works under hydraulic pressure through the pump, valve block, pipework and rams, so a leaking or binding actuator can quickly turn into fluid loss, warning lights and poor roll control. This replacement ram replaces RQK100000 and fits front or rear ACE actuator positions on Discovery 2 models fitted with ACE.
Vehicle Fitment
- Discovery 2 1998-2004
- TD5 and V8 models where Active Cornering Enhancement is fitted
- Front or rear ACE anti-roll bar actuator position
Fitment Notes
This part is only for Discovery 2 vehicles fitted with ACE. Non-ACE vehicles use conventional anti-roll bar hardware and do not use this hydraulic actuator ram. ACE is a high-pressure hydraulic system, so the system must be refilled and bled correctly after replacement.
Related Parts
Use the correct ACE hydraulic fluid when working on the system. Ravenol SSF ACE fluid is available separately for Discovery 2 ACE systems requiring STC50519 / LR003401.
