Tomei Japan FORGED H-BEAM ConRods KIT NISSAN A12

FORGED H-BEAM CONROD KIT NISSAN A12　 CONROD Highest quality, stronget A12 Connecting rods! Made to win the race!! The connecting rod exerts a very large force to transfer the combustion pressure received by the piston to the crankshaft. In addition, the balance of the inertia mass greatly affects the smoothness of the engine rotation and the durability at high rotation because it becomes a moving part integrally with the piston. In response to the high durability required from the high rotation speed of A12 tuning in recent years, TOMEI connecting rods meet the requirements such as strength and balance. PRODUCT INFO APPLICATION P/N NOTE NISSAN A12 125010   FEATURE / SPEC CONROD CONROD BOLT CONROD BEARING Length L.Diam*Length S.Diam*Length (Bush Inner Cir) Materiak Bolt Size Height Under Neck Inner Circum Bearing Width 121.5mm φ48×24.3mm φ17.5×22.5mm SMCM439 5/16 38.1mm φ45mm 19.5mm Development Thema Balance of Strength and light weight. Maintaining the rigidity of both the large end and small end. Reduction in the rod from buckling under high stress loads. Small Ends Structure. Balance of inertial mass. The connecting rod bolt to withstands high tensile stress loads. H-BEAM DESIGN The selection process between both I-Beam & H-beam design is usually decided upon the weight, buckling strength & production costs for the conrods. We have designed & made conrods for Nissan RB,SR,VQ, Mitsubishi 4G, Subaru EJ & also for Toyota 3S, 1J & 2J engines. We chose to aim for overall strength while maintaining a light weight design. SECURED CONNECTION STRENGTH The strength of the connection is raised with the design aspects of the meting face of the rod. This minimizes the chances of elliptical deformations caused when under serious stress loads from serious power applications and thus maintaining the correct conrod bearings clearances. STRUCTURE OF THE SMALL END The oil cap bush now has 2 holes for oil to enter for lubrication. This bush experiences high load whilst providing oil hole from the top of the bar when the upper piston pin is pressed down when the conrod rises. Unlike other aftermarket conrod designs our H-Beam conrod design does not have the oil feed in the center of the rod from the big end. This way the center is solid for maximum strength. CONROD BOLTS Conrod bolts are ARP “Custom Age 625 Plus” for even more fatigue / tensile strength and overall durability compared to other applications come with ARP “L-19” conrod bolts. The bolt size 5/16 provides a secure fastening and much improved reliability while avoiding weight gain at the big end. SNCM439 METAL The SNCM439 material is normally used only when considerably high rigidity is required. High strength conditions are key elements for the conrod. Nickel was also added for extra tension resistance. ULTRA LIGHT WEIGHT The lightest weight possible without compromising the conrods strength for high power use.
