3. Insert the bolt head into the slot and add a ½” lock washer and
thread a ½” nut onto the end of the bolt.
Inverted or Upside-Down Installation – Bottom-mounted
Couplers, V-nose Trailers
Install the assembly upside-down if you have a trailer with a bottom-
mount coupler, V-shaped nose, or any other obstacle that prevents
them from being installed right-side up.
1. Slide the assembly up around the frame until the bolt hits the
bottom of the trailer frame with the mounting bolts facing out.
2. Insert the second ½” x 4” bolt through the open hole closest to the
top of the trailer frame. (Figure 11)
3. Insert the bolt head into the slot and add a ½” lock washer and
thread a ½” nut onto the end of the bolt.
No Gaps
For either typical or upside-down installation there should not be a
gap between the trailer frame and the link plate bolts either above or
below the trailer frame. Move electrical or propane lines if necessary.
(Figures 12)
Pinch the link plates flat against the sides of the trailer frame, and
hand tighten both nuts. [FIGURE 13-14]
When the nuts have been tightened by hand and both link plates are
held flat against the frame, use a torque wrench to tighten all the link
plate bolts to 65 ft-lb.
L-bracket Installation
Place the L-bracket onto the outside link plate with the bolts in the
two middle holes. Thread on the nylock nuts and hand tighten them
until the L-brackets are held firmly in place. (Figures 15, 16)
Step 5 – Install Spring Arms
Á
WARNING
Never tow with loose socket bolts. Tighten socket bolts to a minimum of 60
ft-lb before you tow.
Á
NOTICE
Do not pound directly on the sockets to move them.
Pounding may cause the sockets to crack or chip. Use
only the lever force of the spring arm to rotate tight
sockets. Loosen the socket bolt if required when new
to break free from the paint. Retighten them once the
socket has been moved.
The e2 Round Bar arms are
not
side specific. Simply push the arm
with the notched end into the bottom of the hitch head until the
spring bar retaining pin snaps into place. (Figure 17)
To remove the arms, lift the retaining pin tab and pull down or swing
the arm out perpendicular to the trailer and the arm should drop free.
Step 6 – Set Up Weight Distribution
Tools Needed:
• Measuring tape
• Pencil
Good weight distribution is a critical component of the e2 round bar hitch setup. To ensure
proper weight distribution, measure the front fender of the tow vehicle three times in different
vehicle configurations.
1. Measure without the trailer coupled.
2. Measure with the trailer coupled with the spring arms unattached.
3. Measure with the trailer coupled and the spring arms attached.
For best accuracy, measure both the driver and passenger fenders and use the average of these
two measurements for the calculations. [FIGURE 18]
