Aluminium double belt alternator pulley to suit early 12A and 13B rotaries through to series 5 RX-7 (vehicles with 15 mm alternator shaft).

It allows a second v-belt to be added for improved reliability, particularly on high-revving engines.

Two alternator belts of the same size as the original are required. These pulleys do not change the drive ratio of the alternator.

Key benefits:

* Eliminates belt slip on the alternator/water pump/cooling fan pulleys
* Shares the load between two belts
* Back-up belt if one belt fails
