  • Complete Kit: Includes the connecting rod, crankpin, big-end bearing, small-end bearing, and washers for a comprehensive rebuild.
  • Engineered for Durability: Designed to maintain integrity and performance even under high-stress scenarios, making it an ideal choice for both maintenance and engine overhauls.
