XRAY NT1 Aluminium Damper Spring Bottom Red XN1-49/RE by 3Racing  [XN1-49/RE]

Aluminium spring seat for XRAY NT1 shocks

The XN1-49/RE is a replacement spring bottom made for XRAY NT1 dampers, machined from aluminium and finished in red to provide a durable contact point for the damper spring. It is a direct-fit item for NT1 damper assemblies and replaces the original spring seat during maintenance or setup work.

Installation is done during shock disassembly: remove the factory spring bottom and fit this aluminium unit in its place. The part secures spring seating and lets you make fine preload changes; small adjustments at the spring base produce predictable differences in initial compression and chassis pitch under load.

Use this spring bottom as a stable interface between spring and shock body to keep alignment consistent and achieve repeatable preload settings. The red finish makes it easy to identify in a mixed parts drawer but does not alter spring rate or internal damper performance.
