Single Connecting Rods for 2JZ, EJ, K Series, RB and SR Builds

Individual Replacement Rods

A single rod is useful when one cylinder needs a matched replacement after a teardown, bearing concern, or inspection finding. Match the existing manufacturer, series, center to center length, big end bore, small end bushing, and fastener specification before reassembly.

Fitment and installation details

Use the product listing to confirm the exact part number, vehicle configuration, dimensions, hardware requirements, and installation notes before placing an order.

H Beam and I Beam Construction

H beam rods are a popular forged steel choice for durable street and boosted builds. I beam designs can suit high cylinder pressure and high rpm combinations when their beam profile, bolt package, and weight target match the intended power level.

Platform Specific Fitment

This collection includes options for Toyota 2JZ, Subaru EJ, Mitsubishi 4G63 and 4B11T, Honda and Acura K, B, and D series, Nissan RB, SR, KA, and VG engines, and Mazda BP applications. Always verify the exact engine code and wrist pin size.

Use the product listing to confirm the exact part number, vehicle configuration, dimensions, hardware requirements, and installation notes before placing an order.

Rod Length and Piston Compatibility

Center to center length, big end width, crank journal size, small end width, and pin diameter determine compatibility. A single rod must work with the existing piston, crankshaft, bearing shell, and deck height plan.

Fasteners and Machine Work

Rod bolts are a critical clamping component and should match the rod manufacturer specification. Have a qualified machine shop check bore size, side clearance, weight match, torque method, and rotating assembly balance after any replacement.

Common Questions

When should I buy one connecting rod?

Buy one rod when a qualified inspection confirms that one damaged rod can be replaced and the remaining rods are serviceable and compatible.

Can I mix a new rod with an old set?

It is best to match the existing brand, part series, dimensions, and weight group. A machine shop should verify the complete rotating assembly.

How do I identify my rod length?

Measure center to center from the big end bore center to the small end bore center and compare it to the engine specification.

What is the difference between H beam and I beam rods?

The beam profile changes how a rod is designed for loading, weight, and intended rpm. Choose the series recommended for the engine plan.

Do rod bolts come with single rods?

Included hardware varies by part number. Review the product listing to confirm bolt inclusion and the required installation procedure.

Can I reuse the original rod bolts?

Only reuse bolts when the rod manufacturer permits it and inspection confirms they meet specification. New hardware is often the safer choice.

Does a single rod need balancing?

Yes. A replacement rod should be weight checked against the remaining rods and the assembly should be balanced when the build requires it.

Will a 2JZ rod fit every 2JZ engine?

No. Confirm the exact 2JZ variant, pin size, rod length, and piston combination before ordering.

Should I replace bearings with a rod?

Inspect the bearings, crank journal, piston, and cylinder carefully. A failure can affect more than the rod itself.

Who should install a connecting rod?

Engine assembly and machine work should be completed by an experienced builder who can measure clearances and follow fastener procedures.
