Frequently Asked Questions

Are springs and oil included?

No — springs, oil, and installation tools are sold separately. Order the service kit and fork oil before installation.

How do I adjust compression and rebound?

Adjustments are made at the top of each fork leg. Compression is tuned on the left leg, rebound on the right.

Do I need a professional to install this?

Fork cartridge installation requires suspension knowledge and proper tools. Most riders have a suspension shop handle the swap.

Will this fit my 2021+ Harley?

This kit is tuned for 2017-2020 models. 2021 and newer Harley forks use different geometry — verify fitment before ordering.

What makes NIX different from standard cartridges?

The NIX design separates compression and rebound into left and right legs, allowing independent tuning of each function for better control and comfort.
