Honda K20C1 Type-R Wossner A-Beam Connecting Rod Kit The Wossner A-Beam connecting rod kit for the Honda K20C1 engine is the ultimate internal upgrade for the modern era of turbocharged Type R performance. Designed specifically for the FK2, FK8, and FL5 generations, these rods address the inherent limitations of factory components when subjected to increased boost levels and aggressive tuning. By utilising an optimized A-Beam profile, Wossner has engineered a rod that balances high tensile strength with a reduction in reciprocating mass, allowing the K20C1 to maintain its rapid spool characteristics while providing the structural backbone needed for high-torque applications. Precision-forged from high-purity 4340 chromoly steel, each rod undergoes a rigorous manufacturing process in Germany to ensure absolute consistency. The A-Beam design is particularly effective in turbo applications, offering excellent resistance to the compressive loads generated by high cylinder pressures. Each kit is supplied as a weight-matched set and includes genuine ARP 2000 fasteners, providing the clamping force necessary to prevent big-end distortion during high-load pulls. Whether you are aiming for a fast road setup or a dedicated track weapon, these Wossner rods offer the reliability required to push the K-Series turbo platform to its full potential. Key Performance Features Forged 4340 Chromoly Steel: Engineered for extreme durability and resistance to the high-torque demands of the K20C1 turbo engine. Lightweight A-Beam Profile: Optimized strength-to-weight ratio to improve engine response and reduce bearing wear at high RPM. ARP 2000 Series Bolts: Includes premium 3/8" ARP 2000 fasteners for maximum big-end stability and rod-cap security. Shot-Peened Longevity: Surface-treated to eliminate stress risers and significantly extend the fatigue life of the metal. Balanced Sets: Every kit is weight-matched to within +/- 1.5 grams for harmonious engine balance and smooth power delivery. Bronze Wrist Pin Bushings: High-grade bushed small ends designed for fully floating pins, ensuring reliable lubrication under pressure.
