Measuring Height (H)
5. Attach the trailer to the vehicle without the weight
distribution bars connected.
6. Measure the height of the top of the front wheel
opening on the fender to ground, this is height H2.
7. Install and adjust the tension in the weight distribut-
ing bars so that the height of the front fender is
approximately (H2-H1)/3+H1 (about 1/3 the differ-
ence between H2 and H1 above normal ride height
[H1]).
8. The truck can now be driven. Jack mode will be
canceled and vehicle will return to normal ride height
when drive at speeds above 5mph (8kph).
