This 3Racing XN1-49/RE is an RC-scale replacement spring bottom designed for XRAY NT1 dampers, finished in red and made from aluminium to provide a durable contact point for the damper spring. It serves as a direct-fit component for the NT1 damper assemblies and is intended to replace the original spring seat during shock rebuilds or maintenance.
Installation is performed during shock disassembly, where the original spring bottom is removed and this aluminium unit is fitted in its place. The part's role is to secure the spring seating and allow precise preload adjustments; small changes at the spring bottom translate to predictable effects on initial spring compression and chassis attitude under load.
For tuning, use this part as a stable interface between spring and shock body to maintain consistent spring alignment and repeatable preload settings. The red finish aids visual identification in a mixed-parts toolbox but does not imply any change to spring rate or damper internals.
