What makes it high steer?
Our Dana 60 High Steer Arms bolt onto the factory knuckle.
By placing the arms on the top of the knuckle you have moved the mounting locations for steering up higher. AKA HIGH STEER.
The factory tie rod location circled in red is considerable lower, than the height of the high steer arm circled in yellow.
How do I set my preload and what should it be?
After your studs have been mounted. To get your preload you will tighten the set screw, putting pressure onto the preload spacer. Tighten until you have between 20 to 25 lbs. of pull. This is a fine adjustment, you will need to tighten and loosen the set screw as needed to get the correct pull weight.
A fish scale is a common tool used when measuring pull. Attach the scale to the knuckle at full turn and pull, the scale will give a reading in lbs. Once the pull weight is correct, recheck to confirm accuracy of measurement. Tighten jam nut. Check this periodically.
