Which Summit UD Pulley?

They have 2 on their website.

This one is 6.140" dia.

and this one is 6.750" dia.

Are they made for different applications? Obviously the smaller diameter one is gonna spin faster and easier and free up more hp. Just wondering if the belts i have will still work for either. I picked up the normal belts you get for an ud pulley swap.

i purchased one on for my ls1 i had in my s10. they are a decent piece, but they were really heavy. i didnt notice any differences with it installed. if i were to buy another one, i think i would spend the money on a more expensive lighter weight balancer.

i still may opt to getting that pulley instead of the ASP. the summit seems like a good quality piece and has a nice finish also. same pulley as the ebay (pro race) and the BBK pulley
