When choosing a pulley set, there are three types to consider: stamped steel, cast aluminum, and forged aluminum. Each offers specific benefits and should be compared to determine the best fit. Pulley size also plays a role in choosing the best set. Stamped steel is affordable, while cast aluminum offers more show appeal and a longer life cycle. Forged aluminum is the best choice for high-performance and top-end capacity.
When choosing the best pulley set, you’ll be required to select your pulleys from three basic types: stamped steel, cast aluminum, and forged aluminum. Each type of pulley set offers a specific benefit and should be compared to other styles to determine the best fit for a given application. Variations between pulleys aren’t limited to materials, and pulley size also comes into play when trying to choose the best set for a particular application. By selecting pulleys with a larger or smaller diameter than stock, you can effectively choose an over or under driven set of pulleys.
Most stock or original manufacturer pulleys feature a stamped steel design. This type can offer you an affordable pulley set and commonly bolts directly into any application where a stamped steel set is originally installed. If you’re looking for a basic, no-nonsense pulley set, you may want to investigate this type. If, however, you are looking for a higher performing set of pulleys with more show appeal, you may want to investigate a cast aluminum set. This pulley design offers a more eye-catching design with a little more flash. For the show vehicle, this can often be the best choice.
For moderate performance and load at a moderate price, the cast aluminum pulley set will usually perform without fault. Pulleys are typically lighter than the stamped steel version. Cast aluminum pulleys, however, are commonly stronger and offer a longer life cycle. Cast aluminum is a good choice if you are looking for a long lasting, moderate performance set of pulleys. Cast iron pulleys are typically capable of withstanding all of the most extreme belt tensions and speeds in any manufacturing application, and the aluminum design also makes it the best choice for you when cost and heat dissipation are an issue .
At the higher end of pulleys designed for performance, forged aluminum sets are often the better choice. You will be able to run a car at the top end of its capacity without pulley breakage with a forged set. These pulleys are hands down the truest and most balanced of any pulley on the market. Created from a billet piece of aluminum, the pulley set is carved on a precision lathe to exacting tolerances. Once created, the entire set is balanced to give you the smoothest pulley available. If your search is for the best pulley made, you may want to choose the forged set in any size over or under drive.
