Tech Insight

The secondary nut (lock nut) plays a critical role in maintaining consistent ride height and preload settings. After adjusting the primary spring collar, the secondary nut locks the adjustment in place to prevent movement caused by vibration and suspension cycling.

Running without a properly tightened secondary nut can lead to preload changes, inconsistent handling, and uneven suspension performance. Replacing worn hardware during routine service helps maintain dependable, race-ready performance.
