- Wheels & Tires
Lightweight pulleys are a great way to improve your engines efficiency. The easiest way to explain "what a lightweight pulley does" is to compare every spinning object on your vehicle to your shoes. It is easier to run in lightweight track shoes than it is to run in work boots. The same goes for your engines ability to spin your pulleys, flywheel, wheels, driveshaft, etc. All rotating assemblies of a vehicle take horsepower to spin them. By reducing this weight you are transferring more power to the rear wheels, asking the engine to do less work, and ultimately improve the efficiency and performance. Lightweight pulleys are one of the best "bang for the buck" mods you can make.
