INITIAL SET-UP
1.
Line up tow vehicle and trailer on level pavement, in straight-ahead position, uncoupled.
2. Level the trailer and measure and record the distance from the ground to the top of the ball socket (X dimension Fig.1).
3. Select a hitch ball with a diameter that matches the trailer coupler size. The three most common sizes are 1-7/8", 2",
and 2-5/16". Select ball with 1-1/4" or 1" threaded shank that is V-5 rated equal to or greater than trailer gross vehicle
weight rating (GVWR). A thin jam nut (.72” thick) should be used on standard ballmount to prevent interference with
spring bar trunnion.
WARNING: Raised balls usually have reduced load ratings. Ball rating MUST equal or exceed trailer GVWR.
4. Attach hitch ball to the ballmount (G). REESE standard height hitch balls with 1-1/4" shanks are supplied with
lockwashers and nuts (If you must use a 1” shank ball, use bushing 55030 (B) to reduce hole size in ballmount (G) to
1”). Always use a lockwasher and place washer next to nut. Unless otherwise specified by ball manufacturer torque ball
nut to 450 ft/lbs for 1-1/4" nut, 250 ft/lbs for 1" nut.
5. Some installations may require a longer hitch bar (D). Extended bumper guards, pickup truck "caps", or rear mounted
spare tires can limit turn angles unless a longer bar is used. Individual hitch bars (D) are available in various sizes.
6. Insert the hitch bar (D) into the hitch box and install a pull pin. Place ballmount (G) onto hitch bar and move up or down
for proper height. Hitch bar may be used in either the up or down position (see below).
NOTE: Ball height should be greater than coupler height (measured in step 1) to compensate for vehicle "squat”
(approximately 3/4” to 1”).
