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.

Nice 3.0 pulley

Welll was a nice little upgrade, went from a 3.1 pulley to a 3. Noticed a difference along with the 3inch down pipe. Satisfied with the installation also had to get a slightly smaller belt but again worked out great :)

Noice!

Got it next day to Canada, was pretty impressed. Working great, wish you guys had a few options in 5 rib pulleys but it’s all good!

Super charger pulley

Ordered a 2.7 to replace a 3.0. Shipping was excellent. They noted to check clearance with the blower snout. I used some emery cloth to remove casting roughness and it fits perfect.
