Technical spring seat for XRAY NT1 dampers

The XN1-49/RE is an aluminium replacement spring bottom engineered for XRAY NT1 damper assemblies, finished in red to simplify parts tracking. It provides a consistent seating interface for the spring and is intended for rebuilds and setup regimes where repeatability matters.

Installation requires full shock strip-down so the factory spring bottom can be removed and this unit fitted. The component maintains concentric spring alignment and enables precise preload adjustments; small base-level changes translate into measurable shifts in initial compression and dynamic chassis response.

Use the part as a stable mechanical reference during setup cycles to reduce variables between runs. The anodised finish is cosmetic and corrosion resistant; it does not alter spring rate or damper internals but does improve serviceability and identification for race-day pit work.

What tolerance should I expect for fitment?

The part is produced to match XRAY NT1 damping interfaces for direct replacement; verify fit at assembly and check for free spring movement before full reassembly.

How does this affect setup repeatability?

By stabilising the spring seating geometry, the unit reduces variation in preload and alignment, which improves repeatability across shock rebuilds.

Any service considerations?

Inspect the seating surface during routine service for burrs or debris, clean before reassembly and torque any fastenings to recommended values to preserve alignment.
