Upgrade your front suspension with a high-performance fork kit that replaces traditional damper-rod internals with gas-charged, single-tube inserts for noticeably better damping and control. 🛠️🏍️

The kit contains gas-charged fork inserts and custom-tuned springs to improve resistance to front brake dive, enhance front-end stability, and reduce bottoming during aggressive cornering.

No fork modification is required for installation; lowering options can drop the front end up to 2" (lowering kit not for use on low models). Made in the U.S.A.
