ASSEMBLY & INSTALLATION
Step 1:
Insert adjustable shank bar(#4) into receiver tube on tow vehicle and
secure with hitch pin&clip(#6).
NOTE:To obtain proper ball height on high ground clearance
vehicles,shank may be inverted as shown below.If shank is used in the
inverted position,check for adequate ground clearance.
Step 2:
Torque ball to 360ft-lbs.Secure the ball to the head assembly(#1) using a
lock washer(#8) and nut(#9).
Step 3:
Position head assembly on shank. Slide head up or down to the nearest
bolt hole alignment position which corresponds with the target ball height
determined earlier.Mark the position on the shank.

- 6 -
Step 4:
Install the head on the shank at marked position.Insert the 3/4”-10 x 5”
hex bolt(#10) through the 3/4” conical washer(#11）and then through the
lower hole in the head channel.Rotate the head forward as far as it will
go. The ball should be vertical or tilted slightly back.If it is not,adjust set
screws(#13).Install the remaining 3/4”-10 x 5” hex bolt(#10) with 3/4”
conical washer(#11）through the upper slotted hole. Install a second 3/4”
conical washer(#11）on both bolts. Start 3/4”-10(#12) nylock nuts and
finger tighten only.
Step 5:
Tighten top 3/4”-10 x 5 hex bolt(#10) just enough to hold head tight
against the pin in the head channel. This bolt will be tightened later.
Step 6: Install spring bars
Apply a heavy grease on the round end of each spring bar and push end
up into the head socket until you hear a click, as shown below. This will
indicate that the spring bar is locked into place. To release spring bar, lift
up slightly on spring bar and gently pull out on the retaining pin in the
hitch head. The spring bar will be dropped free of the hitch head.
Step 7: Attaching the trailer to the ball
Using the trailer tongue jack, lower the coupler onto the trailer ball and
close coupler latch. Do not retract jack fully at this time. Allow the jack to

- 7 -
support some of the tongue weight.
Raise the front of the trailer and back of the tow vehicle approximately 3"
with tongue jack or until the rear bumper is back to the initial measured
height. This will allow easier installation of the spring bars onto the
support brackets.
Step 8:Installing the spring bar support brackets
Mark the position of the support brackets (#3) by making a center line on
the trailer A-frame a minimum of 4" in from the end of the spring bars
(#2).
Step 9:
Assemble and tighten the mounting plate and bracket onto the trailer
A-frame using two 1/2"-13UNC-4"carriage bolts, two 1/2"-13UNC hex
nuts, and spring washers. Then, assemble the L-shaped bracket onto
the mounting bracket and secure it with two hex nuts and spring washers.
All nuts must have a torque of 45-55ft-lbs. As shown in the following
figure.
Step 10:Raise the spring bars
Pull the spring bar out from the A-frame and hook the lift bar into the
L-bracket as shown.

- 8 -
Step 11：
Pry the spring bar onto the L-bracket by rotating the lift bar to vertical.
With the spring bar supported by the L-bracket, remove the lift handle.
Secure the spring bar by installing the retainer clip and cotter pin.
Step 12:
Check the vehicle height and adjust the angle of the head using the set
screws (#13) as required until desired loading is reached. With the
spring bars secured, lower the jack to apply load to the hitch. The vehicle

- 9 -
should settle evenly. Remeasure the front and rear bumper reference
points. If the front has settled much more than the rear, adjust the set
screws until the vehicle and trailer are level. The spring bars should be
nearly horizontal when correct height is achieved.
Step 13：
Tighten all 3/4" bolts and lock nuts to 200 ft-lbs. Tighten the set screw
(#13) to 50 ft-lbs. Failure to tighten the hardware may result in fastener
loss or failure.
Before You Tow：
Check all connections listed below prior to towing:
- Hitch pin & clip (securing shank to receiver)
- Head to shank fasteners
- Trailer ball nut
- Coupler latch
- Spring bar support brackets
- Safety chains
- Lights and turn signals
- Braking system (including breakaway switch)
MAINTENANCE
1. Keep the socket-mounted ends of the spring bars and the lock pins in
the head assembly free from dirt and well lubricated. Excessive wear in this
area may indicate an overload or inadequate lubrication.

- 10 -
2. Keep the head assembly exterior clean. Do not allow dirt or stones to
lodge between the spring bars and the head.
3. Keep hitch parts painted to prevent rust and maintain good appearance.
Do not paint over labels.
4.Keep lift brackets clean and lubricated to ensure ease of operation.
