Description

Extreme DurabilityStainless Steel 316 CNC Machined Internal Steering Stop Lugs


Product Overview:

Our CNC-machined internal steering stop lugs are engineered to prevent over-rotation damage in high-stress cycling and motorcycle applications. Manufactured from marine-grade stainless steel 316, these components provide corrosion resistance, extreme durability, and precise steering control.Perfectly integrated into bicycle headsets or motorcycle triple clamps, these lugs are 5-axis CNC contoured to ensure 45° precision contact surfaces, delivering smooth steering while protecting your frame and fork from impact damage.


Key Features & Benefits
