ARP Rod Bolt Kits for LS, Coyote, Hemi, K20 K24, 2JZ, RB, EJ Engines

What This Rod Bolt Kits Collection Covers

A connecting rod bolt controls cap clamping force during every engine cycle. This collection centers on application specific ARP kits and replacement bolts for OEM and aftermarket rods, with material choices for street, endurance, boosted and high rpm engines.

Application First Selection

Use the collection filters and product notes to match each component to the exact vehicle, engine or system configuration. A correct application match matters more than a general category match when parts must work together.

Core Product Options

The correct rod bolt is defined by the rod design, shank diameter, under head length, thread pitch and required stretch. Never select a bolt solely by engine family when the rods have been changed from the original configuration.

Build the System Around the Part

Verify supporting components before ordering. The best result comes from a matched system with the right specifications, mounting provisions and service requirements.

Performance and Service Planning

ARP 8740, ARP2000 and L19 materials serve different load targets. A higher strength material can suit higher cylinder pressure and engine speed, but every bolt must be installed with the stated lubricant, torque or stretch procedure.

Fitment Details Matter

Compare vehicle configuration, production range, connectors, dimensions and product notes before installation. This helps prevent an avoidable return and keeps the project moving.

Installation and Compatibility

A rod bolt upgrade belongs in a measured rebuild. Check big end bore, bearing clearance, crank journal condition, rod side clearance and piston weight before final assembly.

Confirm Before Final Assembly

Inspect adjacent parts, follow manufacturer instructions and test the system after installation. A careful final check helps protect the investment and confirms reliable operation.

How to Choose the Correct Rod Bolt Kits

• Identify the exact connecting rod manufacturer and part number
• Confirm the bolt diameter, thread pitch and under head length
• Use the rod maker stretch specification when it is provided
• Confirm whether the rod uses a press fit, cap screw or through bolt design
• Choose material based on engine speed, boost, cylinder pressure and duty cycle
• Inspect rod big ends after bolt installation or replacement
• Use the lubricant specified by the fastener manufacturer
• Do not reuse a bolt that fails inspection or stretch testing
• Keep rod caps paired with their original rods during service
• Verify bearing clearances after all rod fasteners are final tightened

Common Questions

Why use rod bolts instead of reusing factory bolts?

A rod bolt has a finite service life and must maintain clamping force under high load. New application specific bolts provide known material, dimensions and installation data for a rebuild.

What does rod bolt stretch measure?

Stretch directly measures bolt elongation as the fastener is tightened. When the rod maker publishes a stretch value, it is often the most accurate way to establish the intended clamp load.

Is ARP2000 stronger than 8740?

ARP2000 is commonly selected for greater load capacity than 8740 in higher rpm or higher cylinder pressure engines. Select the material approved for the exact rod and engine use.

When should I use L19 rod bolts?

L19 is intended for demanding applications where the rod manufacturer specifies it. It requires clean handling and careful installation because material selection must match the rod design and service environment.

Can rod bolts be reused?

Follow the fastener and rod manufacturer guidance. Inspect used bolts closely and replace any bolt with corrosion, damaged threads, unknown history or stretch outside specification.

Do I need a stretch gauge?

A stretch gauge is recommended whenever the rod manufacturer specifies a stretch target. It provides a direct measurement that is less affected by friction than torque alone.

Will an LS rod bolt kit fit all LS engines?

No. LS rod bolt fitment depends on the specific rod design and bolt dimensions. Confirm the engine generation, rod part number and installation method before ordering.

Should rods be resized after new bolts?

Rod big end geometry can change when bolts are replaced or upgraded. Have the machine shop verify bore size, roundness and housing alignment after final fastener installation.

What lubricant should I use on rod bolts?

Use the lubricant and procedure supplied by the fastener manufacturer. Changing lubricant can change friction and produce a different clamp load at the same torque value.

How do I confirm a rod bolt kit?

Match the kit to the connecting rod manufacturer, engine application, bolt dimensions and stated fastener material. Verify the procedure with your engine builder before assembly.
