FRAME ASSEMBLY (Group 1)
1. We assemble the frame on its back to make it easier to install the springs
and axle. Once the springs and axle assembly is installed we will flip the trailer
over to complete the assembly. So first, layout the frame components upside
down as shown. The spring bracket mounting holes should be facing up. All
the decals should be upside down.
2. Attach the spring
hanger brackets to the
frame. The U shaped
shackle bolt brackets
mount to the front and
the C shaped “slip-
per” brackets mount
to the rear as shown.
Use 3/8” x 1” bolts and
nuts. Assemble with
the nuts on the inside of the frame rails. Fully tighten all 8 bolts now.
3. Identify the hitch end of the tongue
by the 3 holes on the left side. Insert
the small wire protection grommet
into the lower hole where shown,
then push it all the way in till it snaps
in place.

4. Pass the wiring harness into
the grommet and out the front
end of the tongue as shown.
Stretch out the white wire and
leave an equal length of the
green/brown/yellow wire outside
the grommet as shown. This
length of wires will be the con-
nector to your tow vehicle.
6. Now its time to pass the wire ends thru the tongue.
Make sure the wires are tangle free, then attach a
weight to the end of the wires. A large socket works
great as shown or you could tape a big bolt to the
wires. Tip the tongue up and let gravity work for you.
Feed the wire and let the weight slide through the
tongue pulling the wires with it.
5. Roll this wire so it
doesn’t get accidentally
pulled inside the tongue.

7. Installing the rear tongue support
bracket. First we lay the tongue back in its
place making sure its upside down. Push
the large wire protection grommet into the
rear tongue support bracket hole, then
pass the wires through the grommet. In-
stall the 4-1/2” long x 1/2” bolt up from the
bottom through the tongue support and tongue. Be careful not to pinch the
wires. Add a washer and nut. Hand tighten only.
8. Bolt the tongue support to the frame
rails using 3/8” x 1” carriage head bolts.
Note the square heads go on the outside
with the square holes in the frame. As-
semble with washers and nuts on the
inside. Hand tighten only.

9. Clamp the frame rails around the
tongue as shown using two 1/2” x
3-1/4” bolts. Use a washer on both
sides. Hand tighten only.
10. Lay the two frame cross members
in between the frame rails. The two
holes in the middle should face DOWN
as shown. Bolt the frame rails to the
cross members using 3/8” x 1” carriage
bolts and nuts, (no washers). The square carriage heads go
to the outside with the square holes in the frame rails. Hand
tighten only.

11. TIME TO TIGHTEN
FRAME BOLTS: Its important to
follow this tightening sequence in order
to insure the trailer will be straight after
everything is tight.
A) Tighten the 8 nuts holding the ends
of the two cross members.
C) Tighten the two tongue bolts
snug to the frame rails.
DON”T overtighten, you will just
crush the tongue.
B) Tighten the rear tongue support bracket. Check that
you installed washers under the 4 nuts as shown. Evenly
tighten the 4 nuts.

D) Tighten the big bolt thru the rear
of the tongue and tongue
support. Not too tight, don’t
crush the tongue or support.
Your frame assembly is now complete and should look like this.

SPRING AND AXLE ASSEMBLY
(Group 2)
2. Spin the axle to find the side with the spring
centering holes. These holes mate with the spring
center stud (shown to the left)
1. Set the envelope containing the manufac-
turer’s certificate of origin (MCO) and VIN labels
aside in a safe place.

4. Run each nut down UNTIL IT
TOUCHES THE PLATE ONLY!
DON’T TIGHTEN !!
You will need to wiggle the
springs to fit them into the
spring brackets in the next step.
5. Lift the axle/spring assembly to the trailer frame and slide the slipper spring
ends into the slipper spring brackets as shown.

MPG460G
8. Wiggle the spring eyes into the front hanger brack-
ets and bolt using 1/2” x 3” bolts and self locking
nuts. Tighten the shackle bolts ONLY until they grip
the sides of the brackets. This is a hinge, the spring
needs to move freely.
10. Slip the hub caps thru the wheels
from the back then mount the wheels
onto the hubs and hand tighten the lug
nuts.
9. Now that the axle assembly is at-
tached to the frame, tighten the axle
plate U-bolts evenly until there is a
slight bend in the tie plates.
11. Stand behind the trailer, lift
the rear cross member at one
corner and flip the trailer over onto
the tires.
ALWAYS BEND FROM YOUR
KNEES WHEN LIFTING. IF THE
TRAILER IS TOO HEAVY FOR
YOU TO FLIP
SAFELY GET
SOME FRIENDS
TO ASSIST
YOU.
12. Tighten
the lug firmly
to 75 to 85 foot
pounds
of torque.

REFERENCE:
Trailer Wiring Color Code
•Brown = running lights
•Yellow = left turn / left brake
•Green = right turn / right brake
•White = ground
2. Sandwich the license plate mounting
bracket between the left side lamp and the
left side tail lamp bracket. Attach the tail
light using the nuts provided with the lamp
kit. Then mount the right side lamp.
1. Attach the tail lamp brackets to
the frame as shown using 3/8” x 1”
carriage head bolts and nuts. No
washers are needed.
LIGHTASSEMBLY (Group 3)
3. Use the holes just above the
spring bracket to mount the amber
side lamps. Put the stud through
the forward hole and the wire
through the rear hole. Tuck the wire
so the lamp sits flush on the frame.

4. Check that the coil of wiring harness outside the tongue grommet is still full length.
5. Route the
GREEN/BROWN wire along the
RIGHT side of the frame.
Route the YELLOW/BROWN wire
along the LEFT as shown.
6. Use the clips provided to secure the wire to
the inside of the frame channel as shown
7. Route the wires thru the mid cross member as shown then secure the har-
ness in place using the frame clips provided. Use your knife to CAREFULLY
divide 1/2” of the green/
brown wire and the
yellow brown wire just
below the side lamp as
shown.
8. Then grasp either side of the cut with your fingernails
and pull to separate 3” of wire as shown.

9. Press the brown wire into the quick connector
as shown. Then insert the wire from the side
marker light fully into the 2nd opening. Use pliers
to squeeze the conductor blade down and thru
the insulation. The blade cuts thru the insulation
and connects the wires inside. Flip the cover to
lock the connector. Repeat on the other side again
using the brown wire.
12. Cut the harness wires off with 10” extra
working length at the tail lamp wires.
13. Strip 1/2” of insulation off the ends of all
tail light wires.
10. Route the harness wires to
the tail lights along the frame.
Use wire clips to secure the wires.
11. Pass the lamp wires inward
through the hole under the tail
lamp mounting bracket.
14. Using your fingers, twist together
in a clockwise motion the lamp
wire and harness wire, of the the
same color. Carefully screw the
wire nut over the twisted copper in
a clockwise rotation. The threads
inside the wire nut will grip the wires
together. Repeat for all four wires.

Note: fenders are
symmetrical and fit on
either side of the trailer.

5. Tighten bolts fully and repeat for other side.
Note that when bolting the mounting brackets to the frame you will install
a washer on both sides, under the head of
each bolt and under each nut.
4. Using 3/8” x 1” bolts, washers on both
sides, and nuts, attach the fender brackets
to the slotted holes in the frame as shown.
NOTE you will use the center hole in the
bracket and the outside two slotted holes in
the frame.

sembly under the tongue and
insert the bolt up through the
skid bolt hole on the bottom of
the tongue as shown.
4. Slip the ring terminal over
the bolt and install the nylon
lock nut hand tight.
5. Check that the rear end of
the skid is still in its hole in the
bottom of the tongue. Tighten
the bolt while holding the nut
stationary. This way the ring terminal remains straight.
