Measuring Departure and Approach Angle
Departure and approach angles are measured by running a string line from the meeting point of the tire and
ground up at an angle to the lowest point on the front or rear of the trailer. These string lines are shown as
dotted lines (Fig.1 and Fig. 2).
NOTE: C-Jacks shown for reference only to mark proper locations.

NOTE: Before checking ground clearance, make sure the trailer is parallel to the plain of the ground and
level front to back.
For the 2K and 3K C-jack Leveling System, follow steps 1-4 for the front and the rear jacks. If installing 5K
Jacks in the rear follow the 5K Jacks section.
NOTE: The height specifications for the C-jack Leveling System is a minimum of 10.5" and maximum 15"
(measured from the bottom of the foot pad to the ground).
2K and 3K C-Jack
NOTE: Figure 3 depicts C-jacks installed onto an OEM cross-member.
1. Align the jack assembly mounting holes with the holes on the mounting bracket assembly across the
chassis road-side to curb-side.
2. Insert six ⁄" - 16 x 1 ½" bolts (Fig. 3A) through each set of aligned mounting holes.
3. Secure the bolts with a ⁄" - 16 nut (Fig 3B).
NOTE: Figure 4 illustrates the ⁄" - 16 x 1 ½" bolt (Fig. 4A) within the C-channel of the mounting bracket
assembly.
4. Connect the wire harnesses to the C-jack motor wires (Fig. 3C).
Run the harnesses to the compartment where the controller will be
mounted.
NOTE: LCI recommends zip tying the wire harnesses tight against the front
C-Jack motors to prevent damage to the wire harnesses.

The trailer MUST be supported per manufacturer's specifications before working underneath. Failure to
do so may result in death of serious injury

5K Jacks
1. Align the rear jack mounting plate holes
with the holes in the rear jack mounting
brackets (Fig. 5B) on the main frame rail
(Fig. 5A). Set the rear jacks (Fig. 5D) at the
proper height to ensure the rear jack foot
panel is within the departure angle of the
trailer.
2. Bolt the rear jacks (Fig. 5D) to the rear jack
mounting brackets (Fig. 5B) using four
⁄" - 16 x 1 ½" bolts (Fig. 5E) and four
⁄" - 16 nuts (Fig. 5C) per jack. Tighten the
bolts to 90 ft-lb of torque.
3. Connect the wire harnesses to the rear jack
motor wires and run the harnesses to the
compartment where the controller
will be mounted.
4. Repeat steps 1-3 for the other side.
NOTE: LCI recommends zip-tying the harnesses
tight against the rear jack motors to
prevent damage to the wire harnesses.

Power Tongue Jack
1. Remove the foot pad from the Power Tongue Jack, if necessary.
A. Remove the hairpin cotter pin (Fig. 6D) and clevis pin (Fig. 6B) holding the foot pad (Fig. 6C) to the
jack leg (Fig. 6A). Set the pins and the foot pad aside.
2. Support the trailer according to manufacturer's instructions. Remove fasteners from the Power Tongue Jack.
3. Carefully slide the jack leg (Fig. 7A) through the hole in the coupler (Fig. 7B) on the trailer A-frame
(Fig. 7C).

4. Align the 3 holes in the Power Tongue Jack mounting plate (Fig. 8A) with the 3 holes in the coupler
(Fig. 8B).
5. Secure the Power Tongue Jack to the coupler plate with three ⁄" - 16 x 1" serrated flange Grade 5 Zinc
coated bolts (Fig. 9A).
6. Connect the two Deutsch Connectors from the jack to the Tongue Jack Harness.
7. Connect the power wire from the Power Tongue Jack to a 30 amp fuse, then to a grounded 12V power
supply on the trailer.
NOTE: The Power Tongue Jack has an option to replace the foot pad or attach the Drop Leg foot pad.
8. Reattach the foot pad to the jack leg by sliding the foot pad back over the bottom of the jack leg.
Secure it with the clevis pin and cotter pin which were previously removed (Fig. 6).
NOTE: The Power Tongue Jack has an option to replace the foot pad with the Drop Leg foot pad.
9. If using the Drop Leg foot pad, attach the foot pad (Fig. 10C) to the jack leg (Fig. 10A). Secure it with
the snapper pin (Fig. 10B).

Determining the Mounting Position and Installing Leveling Sensors
Mounting Position of Leveling Sensors
The leveling sensors have a limited
mounting area for proper performance. The
front sensor must be within 36” from the
front of the frame as signified by Section
A in (Fig.11). Ensure that the front sensor
is mounted in front of the front leveling
jacks. The rear sensor must be in line with or
behind the rear leveling jacks, as signified
by Section B in (Fig.11 and Fig. 12). Both the
front sensor and the rear sensor must also be
mounted in line with the center of the frame,
as signified by the dotted blue centerline in
(Fig.11 and Fig. 12).

Installing Leveling Sensors
The Leveling Sensors (Fig. 13) must be installed on cross-members in line with or behind the rear jacks, and
in line with, or in front of, the front jacks, centered curbside to roadside on the trailer with the arrows on
the top of the sensor pointing the correct direction (Fig. 14). See (Fig. 11), Sections A and B and Figure 12,
Section B for location clarification.
Fig. 13
NOTE: The following process will be repeated for both sensor installations.
NOTE: Leveling sensor mounting plate might be pre-installed by LCI, if so perform step 2 and step 4.
1. Dry fit the mounting plate (Fig. 15C) and the leveling sensor (Fig. 15B) to the cross-member (Fig. 15A).
The pre-drilled holes in the plate are for mounting the sensor to the plate. Mark on the plate where the
sensor will set.

NOTE: Leave space between the sensor (Fig. 15B) and cross-member (Fig. 15A) so the wire harness will not
be pinched.
NOTE: The wire harness must be oriented towards the front of the trailer (Fig. 11 and Fig. 12). Proper
orientation of the wire harness is imperative for correct operation of the leveling system.

2. Attach the sensor (Fig. 16A) to the mounting plate (Fig. 16B) using two #12 - 14 x 1" hex head self-
drilling screws (Fig. 16C).
NOTE: To avoid cracking the mounting sensor housing, do not over-tighten the screws.
3. Attach the mounting plate and sensor assembly (Fig. 17B) to the cross-member (Fig. 17A) using two
#12 - 14 x 1" hex head self-drilling screws (Fig. 17C). Ensure that the plate is centered side to side on the
frame and that the sensor is oriented properly. See (Fig. 11 and Fig. 12) Sections A and B for location
clarification.
4. Connect the sensor harness to the 3-Pin connector on the sensor (Fig. 18A) and run the harness
through the frame and up to the compartment where the controller will be mounted.
