ZZP LSJ Modular Pulleys

These pulleys are sold individually for our Modular Pulley System. If you do not already have our Modular Hub, you would want to purchase the full Modular Pulley System, which will come with the pulley hub and a pulley of your choice.

By developing Ecotec specific pulleys we have run all the way down to 2.7" with out snout machining. However each snout is cast and machined differently so we only guarantee down to 2.8" without machining.
