The proper belt to be used for steering on MK4 and MK4i swerve modules with the corresponding 15mm width Base Pulley and Steering Shaft.
Note: The MK4 Swerve Drive Module design was refreshed mid-cycle to use the 15mm-wide version of this belt, instead of the original 9mm-wide belt. If your MK4 uses the narrower (9mm) belt, order it here.
