Thread: L322 takes on Simpson Desert and Cape York

Just had Graham’s LIAMS installed. Really nice controls for this type of trip, with a 3” selectable height range.

One thing I've always wanted to know is if they control the crosslink valves as well? The offroad mode doesn't just control height.

From the system description & operation guide:

The following wheel travels are shown for on road and off-road vehicle operation. The difference between the two
operating conditions is a result of operation of the cross-link valve. When the cross-link valve is opened the
suspension travel is as given for off-road wheel travel. When the cross-link valve is closed the suspension travel given
for on road applies.

FRONT:

The off road mode wheel travel is:
l 175 mm bump
l 95 mm rebound
l This gives a total of 270 mm off road suspension travel.

The on road standard wheel travel is:
l 115 mm bump
l 155 mm rebound
l This gives a total of 270 mm on road suspension travel.

REAR:


The off road mode wheel travel is:
l 190 mm bump
l 140 mm rebound
l This gives a total of 330 mm off road suspension travel.

The on road standard height wheel travel is:
l 140 mm bump
l 190 mm rebound
l This gives a total of 330 mm on road suspension travel.

I’m sure Graham will give you an answer. As I understand the system it indirectly controls the height. The LR system seems to think its a normal height at all settings. I think Graham’s system essentially tricks the EAS into believing -25mm is normal, +25 is normal and +50mm is normal. The system adjusts the air pressure to EAS to ensure its at ‘normal’ height setting.

The cross-link valves don't control height but perhaps on the pre-TR L322s the cross-link valves might be open whenever in off-road height mode.

LLAMS doesn't control any valves directly, only as stated above whereby the height sensor signals are altered to make the suspension ecu think that the vehicle is higher or lower than it is thus causing the suspension ecu to increase or decrease air-spring air volume until the height sensor signals are within the tolerance band of the target height.

Hey thanks for the info. Do these kits work with early models so the 2002-2005?

They do except that I don't have connectors to plug and play so the connection to the height sensors has to be hard-wired. It'ss fiddly but not too bad a task as the suspension ecu is under the passenger end of the facia.
