CAUTION: The tongue weight rating of the spring bars

represents the capacity of a pair of bars, not an individual

bar. Always use a pair of spring bars and be sure they are

of the same weight rating.

The loaded ball height should never be greater than the

uncoupled ball height. Front wheel overload and loss of rear

wheel traction can result and can lead to unstable handling.

It can reduce braking ability and create a tendency to

jackknife when turning and braking at the same time.

If the loaded trailer ball height is greater than the uncoupled

height, reduce take-up on the spring bar, remeasure and

adjust until the proper height is obtained.

Keep the socket-mounted ends of the spring bars and

the lock pins in the head assembly free from dirt and well

lubricated. Excessive wear in this area may indicate an

overload or inadequate lubrication.

Keep the head assembly exterior clean. Do not allow dirt

or stones to lodge between the spring bars and the head.

Keep hitch parts painted to prevent rust and

maintain good appearance. Do not paint over labels.

Keep lift brackets clean and lubricated

to ensure ease of operation.

Step 6 Tighten 3/4" - 10 bolts (#7, #9) just enough to hold the spacers (#6) into the hitch head (#1). These bolts will be tightened after the correct tilt setting has been determined. Install the spring bars Secure the two spring bars (#3) with the supplied pins (#10). Figure 8 Step 3 Slide the L-support in between the two captive channel brackets as shown above. Set the bracket height closest to the spring bar position set with the jack earlier.

Tighten head fasteners Step 2 Pry the spring bar onto the L-bracket by rotating the lift bar to vertical. After the correct tilt position has been determined and the tow vehicle is sitting level, the 3/4" bolts must be torqued. Step 3 With the spring bar supported by the L-bracket, remove the lift handle. Secure the spring bar by installing the retainer clip and cotter pin as shown below. Tighten 3/4" bolts and locknuts to 200 ft. lbs. Failure to tighten bolts may result in a complete system failure.

TOWING TIPS Driving a tow vehicle Good habits for normal driving need extra emphasis when towing a trailer. The additional weight of the trailer affects acceleration and braking. Extra time should be allowed for passing, stopping and changing lanes. Signal well in advance of a maneuver to let other drivers know your intentions. Severe bumps and badly undulating roads can damage your towing vehicle, hitch and trailer, and should be negotiated at a slow, steady speed.
