Billet Proof Designs

Billet Proof Designs specializes in designing and manufacturing custom aftermarket motorcycle parts for your chopper, bobber, café racer, Harley Davidson, Triumph, Can Am Spyder and even your pants-pocket with our repurposed fire hose wallet. Our popular "Builders" Line focuses on battery boxes, license plate brackets, seat hinges and fuel gauge kits that only require minor fabrication for installation and are made right here in the USA. If you’re sick of the same old chopper parts out there… Look no further.
