ZPI or NST crank pully? - Toyota Yaris Forums

Okay, some of you still aren't convinced. Here is a couple more reasons.

First of all, weights...
ZPI pulley - 14.4 oz
NST pulley - 12.5 oz

Second of all, has anyone noticed that ZPI's pulleys don't come anodized? Hard anodizing does more than just make your pulley look pretty. It actually makes the pulley stronger. Aluminum is a rather soft metal by design, but hard anodized aluminum is stronger and will resist the sands of time better than untreated aluminum. ZPI will charge you 20 bucks extra to anodize your pulley. NST includes anodizing at no extra charge. They don't cut corners.
