XRAY NT1 Clutch Spring - Hard Tune - Arrowmax AM-NT1-330002  [AM-NT1-330002]

Performance clutch spring for XRAY NT1

The Arrowmax AM-NT1-330002 hard clutch spring is a direct replacement for XRAY NT1 clutch assemblies. Made from spring steel, it delivers a firmer spring rate than softer options, allowing tuners to alter engagement behaviour without swapping clutch shoes or the bell.

Use this spring when tailoring clutch engagement to specific track surfaces or driving style. It increases initial bite and helps limit slip under load, though it results in a firmer feel at engagement.

Installation is straightforward for experienced model tuners: seat the spring correctly in the clutch assembly, confirm there is no interference with the bell or shoes, and run controlled break-in laps to verify engagement characteristics.
