The Arrowmax AM-NT1-330007 is a spring cup crafted for XRAY NT1 shock assemblies and supplied in the 7075 HARD aluminium grade. It acts as the seat for the spring end and gives a tougher contact zone intended to lower wear on the original shock components.
This item is compatible with XRAY NT1 style shocks; verify your shock top or lower seat dimensions before fitting. Installation is carried out by removing the existing spring cup, fitting the Arrowmax unit to the identical seating point, and refastening with the original shock hardware. No special machining is normally necessary.
In practice the cup helps preserve repeatable spring position and prevents progressive seat deformation under frequent setup changes. Fit it when you require a firmer spring seat for consistent indexing through multiple sessions.
