Engine & Vehicle Fitment

These rods are a direct‑fit performance upgrade for the Mitsubishi 4G63 engine family, which includes engines used in:

• Mitsubishi Eclipse (various turbo models)

• Mitsubishi Lancer / Lancer Evolution (Evo) 4G63 variants

They are suitable for both street performance and high‑power builds (e.g., turbo engines, higher boost levels) and are a common upgrade when building a more reliable bottom end.
