Ultra Connecting Rod Threads

Callies Performance Products has perfected a thread generating process that creates completely formed thread flanks that are uniform and free of surface imperfections.  Attention to this detail results in greater flank to flank contact within the bolt to rod interface.   This improved interface, combined with unsurpassed thread surface finishing, provide the industries smoothest, most consistent feel when torqueing and stretching rod bolts.   This caliber of thread is standard on all Ultra connecting rods by Callies.
