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

Red aluminium spring bottom for NT1 dampers

The XN1-49/RE replaces the factory spring seat on XRAY NT1 damper assemblies and is turned from aluminium with a red finish for durability and easy identification. It provides a firm seating point for the spring during rebuilds or routine service.

Fitting requires shock teardown so the original spring bottom can be removed and the aluminium replacement fitted. The component lets you set accurate preload because small changes at the bottom translate directly into initial spring compression and vehicle attitude during load transitions.

Keep this part in your tuning kit to preserve spring alignment and ensure repeatable preload between runs. The colour is purely for visual reference and does not change the spring rate or damper internals.
