Hey Steve -
We buy these in bulk direct from the manufacturer, so there’s not really a name brand to assign to them. However, I can assure you that these are not ‘bottom of the barrel’ parts. Even after our bulk pricing, we still pay more than it would cost us to buy individual pulleys from the ‘bargain’ sources online.
Also, rather than just sending a bag of components, we assemble and test every piece before shipping. On our idlers, we press in the bearings and make sure the internal spacer is installed properly. On the sprockets, we ensure the bore is correct, preinstall the set screws, and check to make sure the sprocket spins true.
These aren’t Ferrari parts, but they’re definitely not Yugo parts either.
If for any reason you’re not satisfied with what you get, we stand behind our products 100% and will work together to make it right.
