Steps to Calibrate:
1. Measure before hooking up — Use a tape measure to record the height of your truck's front and rear bumpers before attaching the trailer.
2. Attach the trailer (without spring bars engaged) and note how the rear of the truck sags.
3. Engage the spring bars and adjust the chain bracket tension until the truck returns to (or near) its original pre-hitch measurements.
4. Check level — Both the tow vehicle and trailer should be level when calibrated correctly.
5. Adjust the head angle using the heavy-duty adjustable shank to fine-tune leveling.
