*Note: All Kits Currently Shipped Include This Part Standard.
With the option of using a set screw (grub screw) to hold the clamp in tight, we added another procedure to the process of the ViperSharp System. This upgrade is now available for anyone who wants to swap out their old upright assembly for the new version with the set screw option. Purchasing this new upright assembly should not change the functionality of your system. But with the tight tolerances on the clamp there is a possibility that the new upright may not work smooth with older clamps from a different run. If there is an issue with fit to an old clamp please contact us.
This set screw is not necessary for the vipersharp to function properly and this is something included in all systems from early 2018 forward.
