Installation Instructions (continued)
Weight Distribution Head Installation
1. Determine the required ball height:
a. Divide tongue weight by 200 for tow vehicles with
overload springs, divide it by 100 for vehicles
without overload springs and multiply the result to
calculate tow vehicle ‘squat’:
_______ lb. tongue weight
200 (if tow vehicle has overload springs)
–:
OR
100
(if tow vehicle has no overload springs)
= _______
X 1/8"
= _______ " tow vehicle ‘squat’
b. Position trailer parallel to
the ground on a flat, level
surface and measure the
distance from the ground to
the top of the ball cup and
write it here:
_________ " coupler height
c. Add the distance found in step 1a to the distance
from step 1b to get the required ball height:
______ " tow vehicle ‘squat’ (step 1a)
+ ______ " coupler height (step 1b)
= ______ " required ball height
2. Insert Square Shank (1) into tow vehicle
receiver. Secure it in place with the Lock
Pin (17) and the Spring Clip (18).
