Determine the required ball height:1.
Divide tongue weight by 200 for tow a.
vehicles with overload springs, divide it
by 100 for vehicles without overload
springs and multiply the result to
calculate tow vehicle ‘squat’:
_______ lb. Tongue wt.
200 (if tow vehicle has overload springs)
–:
OR
100
(if tow vehicle has no overload springs)
= _______
X 1/8”
= _______ ” tow vehicle ‘squat’
Position trailer parallel b.
to the ground on a
at, level surface and
measure the distance
from the ground to the
top of the ball cup
and write it here:
_________ ” coupler height
Add the distance found in step 1a to c.
the distance from step 1b to get the
required ball height:
______ ” tow vehicle ‘squat’ (step 1a)
+ ______ ” coupler height (step 1b)
= ______ ” required ball height
