Pls can someone tell me the diff between Unortho Under Drives vs OBX Underdrives for a B18C1

Thanks

 

Unorthodox is a much more reputable company than OBX, hence their pulleys are better quality.

 

But are not all under drive pulleys the same - what makes the diff? I figure as long as it has the same dimensions it is all good.

Can you please let me know of something that I am overlooking?

 

Unorthodox uses billet aluminum to make their pulleys and are balanced, Do you kno if OBX makes it w/same materials and quality ? An unbalanced under drive pulley can destroy many parts, such as crank, oil pump, etc....

 

OBX Precision High Tech Power Pulley Kits are perfectly CNC machined and well balanced to increase horse power after installation. Harmonic balancer are also provided to ensure proper balancing of the pulleys during installation.

This is straight from the website so it should be good to go then.
