Overall Assessment

Customers appreciate the appearance and quality of our pulleys, highlighting an enhanced performance upon replacing their stock pulleys. However, some users encountered issues with the provided belts' fit, suggesting inconsistencies depending on the specific long water pump utilized. A few reviews suggested a longer bolt might be needed on the lower pulley due to its thickness. While there were fitment issues, many confirmed they would purchase again if needed, reflecting product satisfaction and trust. A minor critique referred to adjusting the small raised lip for the balancer bolt hole, emphasizing the product's superior features when installed properly.

Need to recommend that a longer bolt be used on the lower pulley to the crank shaft because of the thickness of the pulley.
