These are the pulleys supplied with the AiM Steering Angle Sensor (Part No. MC-215). Replace a lost or damaged pulley, or move an existing sensor to a new vehicle without a lot of hassle. The steering shaft pulley fits a 7/8" diameter shaft; smaller shafts will need to add a bushing.
We also offer the Replacement Steering Sensor Belt, Part No. MC-336 (sold separately).
