Stronger, Lighter, Improved Response & Designed For Big Race Engines!!
The connecting rod's role is to transfer the compressed pressure that the piston receives to the crankshaft. When the connecting rod becomes one with the piston, the connecting rod's inertial weight and balance then play a major factor in the smoothness of the engine's rotation assembly and durability at high RPM. The weight factor itself will dramatically change the engine's characteristics. The overall strength, balance, and lightweight properties that the TOMEI connecting rod design will take your engine to the next level.

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.
REAL STRENGTH
When the rigidity is insufficient enough at the large end, the metal housing can deform, which can cause metal burns. In order to guarantee overall strength where the rod is connected, the large end was made smoother, and the “shoulder form shaped” was adopted.
SECURED CONNECTION STRENGTH
The strength of the connection is raised with the design aspects of the mating face of the rod. This minimizes the chances of elliptical deformations caused when under serious stress loads from serious power applications and thus maintains the correct conrod bearings clearances.
PROTECTING THE CRANK THRUST FACE
If the thrust aspect of the connecting rods' large end is designed as a simple circle, the conrods' side will cause irregular wear on the crankshaft's thrust area and thus shorten the life of the crankshaft.
The TOMEI conrod thrust protector is designed to come into contact with the entire contact surface area rather than just the thrust aspect of the crank.
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 an 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
ARP L19 rod bolts were selected for our applications due to their superior strength and fatigue properties. A special thinner frame was designed with minimal burden on the threads. The threads was cut into the connecting rod side since no nuts are used, which helps with weight reduction. This design promotes strength while benefiting from weight reductions. L19 is the top range type of ARP rod bolts used since it’s a much higher strength material compared to the ARP2000 and is capable of delivering the highest clamp loads possible.
SNCM439 METAL
The SNCM439 material is normally used only when considerably high rigidity is required. High-strength conditions are key elements for the conrod for supporting a highly efficient turbocharged engine. Nickel was also added for extra tension resistance.
KNOCK PIN
To help prevent burns where the metal connects, a knock sleeve is inserted in the bolt hole to help reduce any gaps between the face of the rod side and the cap side. This maintains a more secure fitment.
ULTRA LIGHT WEIGHT
The lightest weight possible without compromising the conrod's strength for high power use.
ARP MOLYBDENUM GREASE INCLUDED
Balance of Strength and light weight. Maintaining the rigidity of both the large end and the 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.
The ARP Molybdenum grease is highly resistant to heat and pressure, enabling an accurate torque figure when tightening the fastener.
