An improved two-piece connecting rod ( 800 ) that connects a reciprocating piston with a crankshaft in an internal combustion engine. The connecting rod ( 800 ) has a shank portion ( 810, 860 ), a cap portion ( 820, 870 ) and projections ( 830, 880, 882 ) extending from one or both of the shank ( 810, 860 ) and cap portions ( 820, 870 ). When the shank ( 810, 860 ) and the cap ( 820, 870 ) are connected, the projections ( 830, 880, 882 ) mate with the opposite side with an interference fit, thereby resisting relative motion between the shank ( 810, 860 ) and the cap ( 820, 870 ) along the split-line (A').
