Honda K20A Type-R Wossner A-Beam Connecting Rod Kit The Wossner A-Beam connecting rod kit for the Honda K20A Type-R engine is the definitive choice for enthusiasts and professional engine builders seeking to push the limits of the K-Series platform. Specifically engineered for high-revving, naturally aspirated applications, the A-Beam (often referred to within the Wossner range as an optimized I-Beam variant) provides a superior strength-to-weight ratio. By utilising advanced 4340 forged steel, these rods significantly reduce reciprocating mass compared to traditional H-beam designs, allowing your K20A to climb through the rev range with increased throttle response and reduced parasitic loss. Every Wossner rod set is manufactured with obsessive attention to detail, featuring a shot-peened finish to eliminate surface stressors and increase fatigue life. Designed to withstand the violent tensile loads of 9,000+ RPM shifts, this kit comes complete with genuine ARP 2000 series bolts, ensuring maximum clamping force and big-end stability. Whether you are building a circuit-spec EP3 or a high-compression DC5, these rods provide the structural integrity required to protect your investment under extreme competition conditions. Key Performance Features Premium 4340 Forged Steel: High-tensile chrome-moly construction for maximum durability under high-load racing conditions. Precision Balanced: All sets are weight-matched to within +/- 1.5 grams to ensure smooth engine operation and reduced vibration. ARP 2000 Fasteners: Supplied with industry-leading 3/8" ARP 2000 bolts for ultimate big-end security. High-RPM Optimization: The lightweight A-Beam profile is specifically designed to handle the stretching forces of high-revving Type-R engines. Shot-Peened Finish: Increases surface density and fatigue resistance, preventing cracks during prolonged high-stress usage. Bushed Small Ends: Precision-honed bronze bushings for fully floating piston pins, reducing friction and wear.
