4-4. Once you have your brackets loosely connected, pull the top of the bracket sets away from the coupler until the top
and bottom bolts rest on the frame and the chains are tight — the brackets will now be angled as seen below. Now
tighten down all four bracket bolts using two 15/16″ sockets or wrenches.
4-5. Make sure all brackets are clamped tightly — we recommend around 75-90 ft-lbs of torque depending on your frame.
4-6. Using a 5/16″ allen ratchet or allen wrench, screw in all set screws until they
barely touch the trailer frame. Then, proceed to tighten them 1-1/2 to 2 more
full rotations. If you nd that your brackets tend to shift, you can use one of the
following optional set screw installation methods for a more secure connection.
NOTE: If you are installing a kit with Raised 3″/4″/5″/6″ brackets, you will use four
set screws — one set on the outside brackets and one set on the inside brackets
as shown on page 8.
1. OPTIONAL SET SCREW INSTALLATION - PRE-DRILLING
(for both Regular and C-Channel frames)
A good option to strengthen and secure the hold of the set screws is to pre-drill a 7/16″ hole into the frame where the
set screws will be located. Before drilling, insert the set screw into the frame bracket and turn it until the tip makes
contact with the frame, then turn it a little more to apply pressure and make a mark on the trailer frame. Remove the
set screw and drill a hole in the frame at the point you marked. After drilling, replace and tighten the set screws into
the hole to prevent the bracket from slipping.
C-CHANNEL FRAMES
If your trailer has a ‘C-channel’ style frame as shown in the
illustration on the right, you will need to install the set screws or
brackets using one of the two optional methods that follow. Both
optional methods are designed to help ensure a secure hold for
the brackets of your WD kit.
IMPORTANT: Some lighter frames may begin to crush if torqued too high,
so be aware of your frame’s capabilities.
NOTE: Brackets should end up at an angle on your trailer frame
