The Arrowmax AM-NT1-330007 spring cup is an aftermarket shock part made to match XRAY NT1 applications and produced in 7075 HARD aluminium. It provides a robust seating surface for the spring end, aimed at limiting wear at the spring contact point.
Intended for use with XRAY NT1 shock assemblies; always confirm the seat profile on your shocks before ordering. To fit, remove the existing spring cup from the shock shaft, place the Arrowmax cup at the equivalent seat location, and tighten using the original shock fasteners. No additional fabrication is normally required.
Used during setup and tuning to preserve consistent spring position and reduce seat compression or wear. This cup is useful where a harder spring seat is preferred to keep indexing consistent after repeated track sessions.
