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.

3.35" pulley - Stock OEM size

good pulley

Good pulley overall if that tells you anything, it’s just a pulley. If you get the 2.7 you will need a little snout machining to make it work.

2.9

Installed easily and was a perfect fit. Almost like these guys know what they're doing. Mated with the ZZP CAI on my redline, she sings now.

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 :)
