All new lightweight 7075 super strong aluminum transmission pulleys weigh about 1/3 as much as stock pulleys for extended 5th gear bearing life (4-speed pulleys are constructed of 356 aluminum). And lighter weight means more horsepower to the rear wheel. The pulleys are hard anodized for durability. A wide selection of sizes permits fine tuning of final drive ratio. Includes a new spacer, shaft nut, seal and retaining plate with screws. Made in the USA.
