Anyone running a nice aftermarket tensioner? Or, are they a waste of money? Im pretty much done with my build but went with an OEM, now I'm worried it won't hold.

What is your concern with the oem belt tensioner?

I have no concerns at all with the OEM. Not sure why the need to make a $500 aftermarket one. Obviously most aftermarket parts are an improved design but with the tensioner, it never crossed my mind to upgrade one. I' m wondering if anyone's had an oem come apart.

Upgrading your tensioner normally means that the tensioner pulls harder. For that reason I’m not so sure it’s a good idea. These crankshafts are hard to trust as it is. So I just prefer to Stay with the factory tensioner

10 - 4 thanks
I do know that if you run a overdrive balancer like ATI you have to upgrade the tensioner because the larger balancer will hit the tensioner. So you have to upgrade to the thumper tensioner or modify the factory tensioner. That’s one reason someone might decide to upgrade. I just modified the factory tensioner

Unless you're making big power, the stock tensioner will be fine. Belt wrap won't be an issue until you're around the 1000 plus range.
