Application / Fitment Notes

• These rods are made for Chrysler Small Block (Mopar) V8 engines, including popular 318, 340, and 360 blocks, especially in performance and stroker builds.

• The 6.123″ length is a common performance rod length used in many aftermarket rotating assemblies and stroker kits for small block Mopars.

• They suit engines where you want increased strength and reliability over stock rods — ideal for high‑horsepower, nitrous, forced induction, or high RPM setups.

Performance & Build Considerations

• H‑Beam design gives a great balance of strength and stability under load — good for high‑stress areas in performance engines. 

• Forged 4340 steel rods are stronger and more fatigue‑resistant than stock rods.

• These rods typically require matching pistons with the correct wrist pin size and compression height to work with your specific crank and build. (E.g., if using a stroker crank.)Rods are shot‑peened and precision-machined, and the set is balanced within tight tolerances.
