I have only found old posts about pully upgrades. There are a few more companys making light weight pullys for our rides. I think im only looking to replace my pulleys and if im doing this i mazzel go with a light weight set. From what i read i dont want to be underdriven. Bhr has nice sets on their site avail in both standard and underdriven

 

Can I ask why? Pulleys make no actual difference, it's just bling.

 

Simple. Lil bit of weight loss and the fact it has original pullys from 04.

 

i have ud pulleys. the are a little lighter, look nice, and the set of three cost me ~200. i had no issues with being u/d. i had gauges to keep an eye on temps etc, and my car always ran cooler than most but i also did a lot of coolant system upgrades

 

For street would you recommend u/d. I feel i just need standard drive. Im trying to figure out what to do after the Ls coil upgrade.

 

Seeing as 9k is in time out, I'll chime in.

No underdrive pulleys are a waste on a street driven car, and they are D585 coils, never specifically used on a LS1, LS2...

 

i didnt have any issues with mine and as far as coild go just buy bhr and be done with it

 

Bennet built coil kit should be here in a few business days.
