XRAY NT1 7075 HARD Spring Cup by Arrowmax AM-NT1-330007  [AM-NT1-330007]

Spring cup for XRAY NT1

This Arrowmax spring cup is an RC-scale shock component produced for XRAY NT1 series applications, finished in the 7075 HARD specification noted by the part code. It serves as the seating element that locates the spring end on the shock assembly, offering a hard aluminium interface intended to reduce wear at the spring contact point.

Compatibility is limited to XRAY NT1 chassis shock assemblies; confirm your shock top or lower spring seat dimensions before fitting. Installation is straightforward: remove the existing spring cup from the shock shaft, position the Arrowmax cup to the same seating point, and secure using the original shock hardware. No machining or additional tools beyond standard shock disassembly are required for replacement.

In a tuning context this part is used to maintain repeatable spring position and to provide a hard wearing contact surface during repeated runs or setup changes. Use it where a firmer spring seat is preferred for consistent spring indexing and minimal seat deformation over time.
