3Racing XN1-41 19T Aluminium Pulley for XRAY NT1 - Racing Setup Part  [XN1-41]

Technical 19T Pulley Upgrade for Competitive XRAY NT1 Builds

The 3Racing XN1-41 is a competition-focused aluminium pulley for the XRAY NT1 chassis, manufactured to provide consistent tooth engagement and minimal deformation under load. Its 19-tooth profile is selected to optimise drive efficiency while maintaining a practical balance between torque and top speed for race setups.

Racing Performance and Tuning Advantages

In race trim the XN1-41 reduces belt micro-slip and contributes to a more consistent throttle band. Tuners can pair this pulley with specific belt tensions and spur choices to fine tune acceleration response without compromising top end.

Material and Fitment Specifications

Precision machined from aluminium, the 3Racing XN1-41 offers repeatable concentricity and a secure interface with XRAY NT1 shafts. The accurate machining reduces runout and allows predictable behaviour at high RPMs typical of competitive use.

Setup Recommendations for Racers

Fit the pulley with correct axial position and secure fixing torque. Verify belt alignment and bearing condition during installation. For track optimisation, adjust belt tension incrementally and log lap time differences to find the best compromise for your circuit.
