LC AUXILIARY AXLE CONTROL KITS
LIT NO: H830
DATE: April 2019
REVISION: A
Hendrickson Auxiliary Axle Systems announces the launch of our new LC Auxiliary Lift Axle Control Kits. The LC control
kits are designed to accommodate a variety of lift axle applications and will replace the existing HAC auxiliary lift axle
control kits. The new LC kits utilize diaphragm-operated valves, which eliminate the sticking that is common with spool
valves like those used in the HAC controls. Diaphragm valves also outflow similar sized spool valves, resulting in quicker
lift timing. The LC components have a long history of reliable service and are designed to survive the harsh truck and
trailer environment with or without an enclosure. The table below shows the available models as categorized by the
master control mounting location and the lift axle application. The LC auxiliary lift axle controls kits will be available for
purchase beginning April 2019.

All LC kits come standard with one (1) one master control assembly, one (1) secondary (slave) assembly, and one (1)
pressure protection valve for a single lift axle application. All outside-mounted kits also include an optional electric
override switch. This switch can be installed in the cab to give the driver temporary override control without exiting the
vehicle. Reverse kits include a reverse control assembly as well. The master control assembly should be mounted in the
preferred location (inside vs. outside), and the secondary (slave) assembly should be mounted to the vehicle frame
near the lift axle for optimal plumbing and lift timing. The LC kits noted in the table above are designed to re-deploy
to match the state of the air toggle switch in the interior master or the push/pull knob in the exterior master when the
vehicle is powered OFF.

As an alternative to the models listed in the table, two additional LC kits are also available. Contact Hendrickson to
determine if they are right for your application.
LC–MCA – For steerable and non-steer axles. An outside-mounted composite enclosure containing the valve assembly, regulator and gauge only. This kit does NOT include a push/pull valve. A separate electric override switch
is intended to be mounted in the cab to control the state of the axle. LC–MCA is designed to lift the axle to the up
position when the electric override switch (or vehicle) is powered OFF.
LC–MSO – For steerable and non-steer axles. An outside-mounted enclosure containing the valve assembly, regulator, gauge and an external valve stem. This kit does NOT include a push/pull valve. A separate electric override
switch is intended to be mounted in the cab to control the state of the axle. LC–MSO is designed to lift the axle to
the up position when the electric override switch (or vehicle) is powered OFF.This kit also meets the specific mounting requirements of the state of Maryland.
The LC auxiliary lift axle control kits feature color-coded connections, as was standard on the HAC kits (see example
below). These color-coded caps provide for easy identification and reduced installation time.
