Aluminum Alternator Pulley -Double Sheave
74-92 Rotary Engines (All)

The Racing Beat-designed 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 (typically identified by components finished with a bright red or blue finish), a hard-anodized aluminum component will offer comparatively superior durability and wear characteristics. Hard anodized components are typically identified by a darker surface coating, most commonly with a dark grey or black matte finish appearance.

Note: It is not practical to offer a standard replacement belt due to the variations in engine configurations. After measuring the distance required for your application, we suggest you contact your local auto parts store to obtain the required 3/8-inch wide replacement belt.
