Ducmonsta - I verified that my truck has the smaller WG casted calipers, so I ordered the StopTech's that are also WG to replace them. They arrived about an hour ago and are definitely the same caliper (down to the WG casting), just with shinier components and red powder coating.

I was hoping that the faulty nature of the OEM/WG calipers was due to internal components that StopTech upgraded/replaced and therefore they would not suffer the same fate as straight OEM parts, but it seems like that was probably wishful thinking on my part... I wasn't looking to pay for simple powder coating, I was aiming for improvement.

RE: the brake line upgrade - I'm on board with your thought process. This is the first "upgrade" I've done to the truck, so I don't mind spending the $50.

Thanks for the quick response!
