Stop struggling with loose head bearings on your Sur-Ron or Ultra Bee with the Warp 9 Stem Lock Kit. Unlike the OEM star nut, which can move up the steering tube over time, this kit uses a threaded rod running the full length of the steering tube to compress the lower triple clamp to the upper triple clamp, keeping your head bearings secure and tight under all riding conditions.
The lower machined retaining nut includes dual 5mm threads for mounting accessories like fenders, while four black steering tube height spacers (20mm, 15mm, 5mm, 3mm) allow for precise fitment. Durable, lightweight, and engineered for easy installation and long-term reliability.
