Product Description

The Eagle CRS6243R3D is a high-performance connecting rod set built for the Gen III HEMI V8 engines. Designed to cover both the 5.7L (2003-2024) and 6.1L (2005-2010) versions, these rods deliver forged 4340 steel strength with rigorous prep: magnafluxing, shot-peening, sonic & X-ray inspection to ensure integrity even under demanding loads. With a 6.243-inch center-to-center length and .984-inch wrist pin bore, they match the floating pin design used in these engines, making them a suitable upgrade for stock or modified builds that retain pin size and wrist pin type.

Ideal for builders wanting more durability in boosted, high-RPM or heavily used applications, the CRS6243R3D set replaces weaker OEM cast or lower spec rods. Note that fitment is verified through 2024 for the 5.7L applications; **2025 fitment is unconfirmed** for the 6.1L since that engine was discontinued in 2010. Before installation, ensure engine block, wrist pin, and bolt specs match OEM or upgraded standard: using upgraded ARP bolts requires proper torque and lubrication. These rods are not a bolt-on for many performance-trims using 6.4L or Hellcat motors without additional modifications.
