Description
A connecting rod is the critical link between your piston and crankshaft—it must handle extreme forces and maintain precision tolerances or your engine fails catastrophically. The PROX 03.6311 is a complete, ready-to-install assembly that eliminates the need to source and match individual bearing components separately. With everything pre-assembled and tested, you get reliable performance and faster installation, whether you’re rebuilding a high-revving engine or replacing a worn rod.
