Chopper Guys specializes in custom built frames and fabrications. We make some of the strongest frames in the world from our FXR Sportster Style Frames, Rigids, Softails, and Bagger Style Frames.  We were the first company to make a production wide tire frame for FLH Harleys! 


Chopper Guys CPI can custom fabricate parts including oil bags, gas tanks, and anything with sheetmetal! California Performance Iron can create custom CNC parts. CNC means Computer Numerical Control, this means a computer converts the design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material.
