Measuring Departure and Approach Angle

Departure and approach angles are measured by running a string line from the meeting point of the tire and ground up at
an angle to the lowest point on the front or rear of the trailer. These string lines are shown as dotted lines (Fig.1).
NOTE: C-Jacks

(For Aftermarket Applications)
NOTE: Measure from the front of the frame and make a
mark at 60". This will be the maximum allowable distance
for the location of the center of the C-Jack foot pad.
The final location should be as close to the draw bar as
possible, staying within the approach angle (Fig.1).
NOTE: Measure from the center of the rear axle hanger
to the center of the rear C-Jack foot pad. The minimum
allowable distance is 18" and the maximum is 48", staying
within the departure angle (Fig.1).
axle hanger
1. Measure the I-beam mounting bracket and make a mark
at the center. This will be the center of the C-Jack foot pad.
2. Measure from the center of the rear axle hanger (Fig.2A)
and make a mark on the I-beam at 18" (Fig.2B) and at 48"
(not shown) for the minimum and maximum distance. Align
the center of the I-beam mounting bracket between the 18"
mark and the 48" mark, staying within the departure angle
(Fig.1). Ensure the bracket lip (Fig.2C) is flush with the outside
lip of the I-beam.
