Prior to Installation
MAKE SURE ANY POINTS OF CONTACT FOR JACK
STANDS DO NOT RESULT IN DAMAGE TO ANY
PANELS OR LINES UNDER THE TRAILER. IMPROPER
RAISING OR LOWERING OF THE TRAILER COULD
RESULT IN DEATH, SERIOUS INJURY OR SEVERE
PRODUCT OR PROPERTY DAMAGE.
3. Remove the tires and wheels from the trailer.
The suspension should be free from any loads, except
its own weight at this point.
4. Place another set of jack stands under the axles,
close to the U-bolt plates. This will provide support to
the axles and ensure that they do not swing down during
disassembly of the shackle components.
NOTE: Allowing the axles to drop could result in damage
to the wiring for the electric brakes.
5. Remove the two shackle nuts (Fig.2A) on the shackle at
the rear of the front spring.
1. Using the properly-rated oor jacks, lift the trailer
according to the manufacturer’s recommendation until the
wheels are no longer in contact with the ground (Fig.1).
2. Support framework in accordance with the
manufacturer’s recommendations.
Fig.1
NOTE: The bolts are pressed into the shackle plate and
should not turn. However, use a properly-sized box end
wrench to make sure the bolts do not turn during the
removal of the nuts.
6. After the nuts and the shackle plate are removed,
remove the shackle plate with the bolts from the other side.
7. After removing the front spring’s shackles at the
equalizer, repeat the process for the shackles (Fig.2C) that
mate the rear spring to the equalizer.
8. Remove the nut on the cross bolt for the equalizer
(Fig.2B). Again, the bolt may be pressed into the frame
hanger and should not be allowed to rotate.
9. Remove the old equalizer.
NOTE: LCI recommends using new shackle links with
shackle bolts and nuts for installation of the Equa-Flex.
Shackle Link kits not included.

clarification during installation.
Rear Axles
NOTE: When installing the Equa-Flex Equalizer into the
center frame hanger, the Equa-Flex Equalizer label should
be facing out.
1. Install the equalizer bolt through the frame hanger
outside plate, the top most bronze equalizer bushing, and
through the frame hanger inside plate.
2. Use a hammer or a piece of steel tube (for bolts with
a grease tting) and drive the bolt into the frame hanger
outside plate, until the bolt head is seated against the
hanger surface.
Installation
THE TRAILER MUST BE SUPPORTED PER
MANUFACTURER’S RECOMMENDATIONS BEFORE
WORKING UNDERNEATH. FAILURE TO DO SO MAY
RESULT IN DEATH OR SERIOUS INJURY.

3. Both the shackle bolts and equalizer bolt must be
installed from the outside-in towards the center of the
trailer chassis. This ensures that the bolt threads do not
interfere with any other assemblies. This applies to bolts
with or without grease ttings.
4. Thread a nut onto the exposed equalizer bolt thread until
the nut seats against the hanger. Torque the nut until it
bottoms out on the bolt shoulder at 30-50 ft-lbs.
5. Place the axles into the normal operating position.
6. Attach the new shackle links with shackle bolts and
mounting nuts.
7. Torque the nuts until they bottom out on the bolt
shoulder at 30-50 ft-lbs.
8. Repeat steps 1-7 for the opposite side of the trailer.
NOTE: If using the triple axle greaseable bolts with grease
fittings, use any multi-purpose grease marked with the
NLGI code of GC-LB.

Front Axles
1. Install the triple axle equalizer on the roadside frame
hanger with the xed arm (Fig.4) facing the rear of the trailer
and the Equa-Flex logo facing outward.
2. Install the equalizer bolt through the rst bracket
of the frame hanger, then through the topmost bushing
of the Equa-Flex equalizer and, nally, through the second
bracket of the frame hanger.
3. Use a hammer or a piece of steel tube (for bolts with
grease ttings) and drive the equalizer bolt into the frame
hanger. This will seat the serrations of the bolt against
the hanger surface and provide resistance to rotation
when tightening.
Fig.4
NOTE: The equalizer bolt must be installed from the outside
in toward the center of the trailer chassis. This ensures the
bolt threads do not interfere with any other assemblies. This
applies to bolts with or without grease fittings.
4. Install the nut onto the equalizer bolt until the nut seats
against the shoulder bolt. Torque nut to 30-50 ft-lbs.
NOTE: When installing the equalizer bolt nuts, use a
wrench to hold the bolt heads.
5. Repeat steps 1-4 for the opposite side of the trailer,
making sure the xed arm faces towards the rear.

6. For Axle #1 and Axle #3, attach the leaf springs to the
hangers with shoulder bolts and nuts (Figs.5 and 6).
7. For Axle #2, attach the leaf spring to the xed arm of
triple axle Equa-Flex equalizer conguration with shackle
bolt and nut (Figs.5 and 6), included within kit.
NOTE: For Axle #2, using kit #281314, when attaching
the leaf spring to the fixed arm, use the front spring eye
location, see the Parts List section for location.
NOTE: A longer shoulder bolt MUST be used to attach the
leaf spring to the Equa-Flex fixed arm.
8. For Axle #1, Axle #2 and Axle #3, attach all shackle
links to the Equa-Flex pivot arm bushings and the leaf
springs with shackle bolts and nuts (Figs.5 and 6).
9. Torque all nuts until they bottom out on the shoulder bolt
at 30-50 ft-lbs.
10. If using the triple axle greaseable bolts with grease
ttings, use any multi-purpose grease marked with the
NLGI code of GC-LB.
11. The installation of the LCI Equa-Flex Equalizer on a
triple axle trailer is now complete (Figs.5 and 6).
12. Lower the trailer evenly to the ground. Use care to
avoid jarring movement. The trailer must NOT be dropped
to the ground. Make sure the shackle links are upright
and located approximately in the 10 o’clock and 2 o’clock
position (Figs.5 and 6).
