XRAY NT1 Clutch Spring Hard - Race Setup - Arrowmax AM-NT1-330002  [AM-NT1-330002]

Tuning spring for XRAY NT1 clutches

The Arrowmax AM-NT1-330002 hard clutch spring serves as an aftermarket replacement for XRAY NT1 clutch assemblies. Made from durable spring steel, it offers a higher rate than softer springs to change engagement behaviour without swapping shoes or the bell.

Use this spring when you need firmer initial bite and reduced slip during acceleration, bearing in mind it will produce a heavier engagement feel compared with softer springs.

Fitting is straightforward for experienced hobbyists: ensure proper seating of the spring, confirm there is adequate clearance with the clutch bell and shoes, and carry out incremental break-in runs to evaluate performance on your setup.
