Page 2

For vehicles with air springs, air shocks or automatic leveling system, check vehicle owners manual. Unless otherwise
specified, level the vehicle with the vehicle loaded as it will be when towing before setting ball height and attaching
trailer.

PRELIMINARY BALLMOUNT ADJUSTMENT
1.

Install hardware in lower hole of ballmount as shown. Tighten nut enough to prevent easy rotation of ballmount.

Determine spring bar height "Y" using table below. Insert spring bar and trunnion into the ball mount. Swing bar outward
to the same angle as when connected to trailer. Lift up on bar to remove slack. Tilt ball mount for proper "Y” dimension
at end of spring bar.

The ballmount (G) is adjustable through a 15° angle. Each step is approx. 1" (approx. 8" overall) at end
of spring bar.

HIGH-PERFORMANCE BALLMOUNT ADJUSTMENT

Install one adjustment washer (E) on 3/4" X 5" bolt (J) and insert bolt in upper slot in ballmount. Use hole and index
position required to locate the ballmount at the proper angle. Install second adjustment washer using same hole and
index position as first washer, then add lockwasher, and nut. Torque the two nuts (K) to 300 ft/lbs. If proper torque
wrench is not available, torque nuts to 150 ft/lbs then turn nuts an additional 1/4 turn. Do not lubricate the threads.

Install longer 3/4” bolt (J) with two serrated washers (E) as shown. Install lockwasher (L) and nut (K), but allow space
for washers to be positioned and aligned. Align the washers as shown, hold in position, and tighten nut.

CAUTION: Washer MUST BE aligned parallel with teeth on ballmount. Re-check washer alignment after nut is
tightened. Equal number of teeth must show at top and bottom. Teeth can be stripped when loaded if not properly
aligned.
