Does anyone make lightweight pullies for the G8? Not underdrive or overdrive. Stock size just lighter. I had a lightweight crank and alternator pulley on my cobalt.

I too have often wondered this, I've used a lightweight aluminum crank pulley on my last 3 vehicles, but they were high rpm 4 bangers that had to spin up before they even think of making power compared to the G8, haha

Maybe that's why I can't find any for my truck, thunderbird, or G8 since they are all V8's lol. I could only find them for my cobalt.

:slap: 4 cylinders only. Engines that produce less torque than it takes to remove our wheel nuts need all the help they can get.

I've been wondering if some of the pullies for the Corvette will work. If the alt pulley and others are the same, then no reason they shouldn't. GM reuses so many parts, it would only make sense that things like the alternator pulley might be the same across 30 different cars. Why have 100 different pullies?
