0A3 Gearbox VSS Trigger Ring [B3/B4]
The 0A3 transmission does not have provision for an on-board VSS (Vehicle Speed Signal) sensor, instead factory cars equipped with this transmission used a wheel speed sensor to provide a VSS feed into the cars various electronic systems such as the ECU, TCU, and dash instruments.
Wheel speed sensors cannot be used on the legacy systems due to an incompatible tooth count.
Our 0A3 VSS trigger wheel provides the all important VSS signal when converting your older chassis car to use the 0A3 gearbox. Combine this sensor with our 0A3 VSS Hall Sensor to provide a plug in solution for your 01A and 01E equipped car.
The trigger wheel also acts as a spacer to correctly offset the left driveshaft to the correct length for fitment into the B3/B4 chassis.
Custom designs can be created to suit your 0A3 installation - please enquire for details.
Machined from 817M40T / EN24T / 4340 & zinc di-chromate plated for corrosion resistance.
This trigger wheel forms part of our 0A3 Gearbox Conversion Kit which also includes the necessary gear shifter linkage and gearbox mounting brackets.
