74-91 Aluminum Alternator Double Sheave Pulley

Belt for this kit can be found here for 79-85, and here for 86-91

Double Sheave Aluminum Alternator Pulley reduces alternator RPM approximately 20% from stock RPM, and is intended for high performance and moderate race use. It is compatible with either the stock main pulley, or assuming you are not using the air pump, our Double Sheave Aluminum Main Drive Pulley. For use on virtually all 1974-92 12A and 13B rotary engines. The weight of this pulley is 7.2 oz.

Precision-machined from billet aluminum alloy, each pulley is finished with a hard anodized surface treatment to ensure superior longevity and excellent abrasion resistance. As compared with standard anodizing processes, a hard-anodized aluminum component will offer comparatively superior durability and wear characteristics.
