Warp9 Racing Stem Lock Fender Adapter

Eliminate Loose Head Bearings with the Warp9 Racing Stem Lock Fender Adapter

Tired of your head bearings constantly coming loose on your UTV? The culprit is often the OEM star nut that slips up the steering tube. Warp9 Racing's innovative Stem Lock kit solves this problem with a full-length threaded rod. This system dramatically compresses the lower triple clamp to the upper triple clamp, ensuring your head bearings remain securely tightened for a consistent, reliable ride.
