Questions about lower pulley change.
I'd like to know what would be a safe upgrade for the lower pulley on my '18 ZLE? Only mods thus far are Rotofab CAI and KOOKS 2" Long Tube headers into GREEN Cats and AWE catback.
Would like to see a bump in power but again keeping it safe! Do I need anything else to make such a change? Does an overdrive pulley put any additional strain on other components? Thanks Mark

I am pretty sure you can change to a 2.3 upper without any belt slip issues.

swapping you upper would get you a good bump before needing to swap out your lower. Griptec has a few choices and a connector that makes swapping them back and forth pretty easy.

Would going to a 2.25 pulley be doable on pump gas?

Lower pulley is what I'm only interested in at this time.
