March serp belt pulleys with factory brackets

Looks great Greg! Are they anodized or powder coated black? I've seen wave lock washers on alternators before so I think you'll be fine with it. If you want a little insurance you could also use a drop or 2 of light duty (blue I think) Loctite. Light duty so if you ever need to take it off it'll come off easier.

Thanks! I thought it came out good too. Looks unassuming enough. They are powder coated black. I think they offer all their stuff with it now.

I used a lock nut with a nylon insert, so far so good.

Drove it 80 miles through NYC traffic to the track today, went 12.20. Pretty sure I was over 7,000 rpm a few times and it stayed on. Sitting at my friends house who lives a few miles from the track. I pulled in to his driveway and smelled coolant. Popped the hood, antifreeze everywhere! Not sure what it is, probably the water pump. Wondering if the smaller pulleys killed it. Glad I got AAA +!! I am a long way from home
