Ya.......some bling, an easily replaceble pulley bearing, Just a tad larger diameter pulley, and the pulley is not plastic

Billet aluminum pulley has a nice bearing that is held in place by a c-clip. I do not see a c-clip on stock bearing. No particular advantage other than that and both Aluminum and plastic will prolly last equally
![]() If you install an aluminum pulley with c-clip which c-clip is installed against boss on tensioner.......you have to touch up boss with file so c-clip does not touch boss as pulley rotates. I am assuming spring on L98 tensioner is same? I did have one tensioner on shelf with stronger spring starting out at 25 lbs vice 17 lbs (1 out of 4). You can measure tensioner torque using fish scale or bow pull (archery) from any outdoor store. Sent from my iPhone using ZR-1 Net Registry

Hey folks, Rather than start a new topic I figured to chime into this one. No tension or noise issues, but when I had my car on the lift I saw that white tape coming out from the tensioner. I read you can stuff it back in, but being paranoid I'm a replace person. This 95 has only 31K miles so I'm surprised.
![]() I had a new tensioner on the shelf and I figured go for some bling with the Dynomite pulley while I'm at it. Thanks Cliff for the offline consultation. I owe you several beers now. All went well and easy R/R and just a little bit of muscle to get the belt over the alternator pulley. I used the Goodyear Gatorback 4060805. The stock belt (GM 10067477) was fighting me so I cut that biatch off. ![]() Sent from my iPhone using ZR-1 Net Registry

Nice job Craig, a good thing you happen to catch that now rather than later.
I know it is not, but it appears to me that it looks like a Mike & Ike piece of candy sitting in the belt area on the RS top of the pic...shows you where my head is, always thinking about food one way or another.... ![]()

Thanks Tom! You're too funny. That is actually a red cap that is on the end of the hose clamp for the air duct. It won't taste as good as Mike & Ike and a bit more chewy.....lol. Sent from my iPhone using ZR-1 Net Registry
