Range Rover Sport 2005-2009 Roll Stability Control Unit and Sensors
Many models of Range Rover Sport feature variable rate anti roll bars to combat undesirable body roll when the vehicle is driven in a more sporting manner. Electronically controlled by high pressure hydraulics, the system is known as Roll Stability Control or Active Cornering Enhancement (ACE).
Roll Stability Control is fitted as standard on 3.6 TDV8 diesel models and is a very popular option on 4.2 AJV8 Supercharged and 4.4 AJV8 petrol models; it is also found on some 2.7 TDV6 diesels.
The pump, reservoir, valve block and other control equipment associated with the system may be found in the section here, while the specially modified anti roll bars, air springs and other suspension parts are listed in the Front and Rear Suspension sections.
