THE LOCK RING: Itself is an anodized aluminum piece, made of CNC machined material. Versus the common die cast lock rings out there, this one is much stronger, and looks better. It also has grips to tighten by hand, and of course, slots to tighten using the lock ring tool – also available here.
BE CAREFUL: This tool will allow you to tighten the lock ring so much that you can break your headlight reflector in half or crack it. Use a sensible amount of force, and finish the job with some JB weld to ensure nothing ever vibrates itself loose in the long run. Now get to work!
