SIZING WD AND TRAILER HITCH SYSTEMS
•Weigh loaded trailer tongue to determine proper system size.
•Choose a system with tongue rating at or above the actual trailer tongue weight.
•Tongue rating of trailer hitch must meet or exceed the measured tongue weight of the trailer.
OEM hitches may not be rigid enough for tongue weight and may need to be replaced (too much
flex and won’t carry load).
•Total trailer gross weight rating must never exceed tow vehicle rated gross tow rating.
FRAME BRACKET ASSEMBLY (600 and 800 lb kits only, shown in Fig. 2)
•Assemble 5/8” shoulder bolt (L) through hole in pad hanger (M) and outside frame bracket (N) as
shown in Fig. 2. Frame brackets have multiple lower mounting holes used for 3, 4, 5 and 6” tall
frames, insert the shoulder bolt through the highest hole not obstructed by the frame. Assemble
5/8” nylon lock nut (P) and torque to 50-75 ft*lbs. Note: For 5”all frames, the top nut flat may
need to be oriented horizontally to prevent interference with the frame.
•Assemble inside frame bracket (Q) to the outside frame bracket using a 5/8” bolt (R) through the
top hole clamping the trailer frame between brackets. The center of the frame brackets should be
placed according to Chart 1 on page 3. The shoulder bolt will also pass through the inside frame
bracket. Assemble 5/8” lock nuts (S) as shown and torque to 120 ft*lbs.
•Repeat for the other side.
NOTE: During spring bar setup, it may be necessary to use a lower bracket hole to decrease spring
bar load if there is not enough head angle adjustment. The lowest hole in the outside frame bracket
can be used on 3 and 4” tall frames using the additional supplied 5/8” bolt as shown in Fig. 4.
