Product Description

The Eagle CRS5470K3D is a high-performance connecting rod set engineered for Honda/Acura K-series engines (specifically K20A2 and compatible K20Z variants). Built with forged 4340 steel, these two-piece H-beam rods incorporate meticulous machining, finishing (shot-peening, magnafluxing, sonic testing), and tight tolerances to deliver strength, durability, and reduced risk of failure under high load and high RPM. They are designed for performance builds up to ~900 hp, making them suitable for boosted, high-revved naturally aspirated, or track applications.

Fitment is confirmed for Acura RSX Type-S (2002-2004) and Honda Civic Si models using K20Z1/Z3 (≈ 2006-2011 depending on region), requiring pin bore of ~22 mm. They will **not** fit K20A3 engines. Proper matching of pistons, crank journal, and bearing clearances is needed. Build through 2025 is validated for all listed fitments; unlisted engine variants or later years remain unconfirmed.
