Product Description

The Eagle CRS4783N3D connecting rods are a premium upgrade designed for the Nissan RB26 / RB26DETT engines used in 1989-2002 Nissan Skyline and compatible RB26 builds. Crafted from SAE 4340 forged steel, these H-beam rods undergo shot-peening, magnafluxing, and precise machining to offer exceptional strength and reliability under high stress. The floating pin/bushed wrist pin design matches OEM RB26 standards, while alignment sleeves and weight matching ensure smooth, balanced performance in high-RPM/high-boost or high horsepower setups.

These rods are intended for serious performance builds. Stock rods must be removed and replaced; proper torque on the ARP bolts is critical, and matching to correct bearing clearances is required. These rods are **not** universally compatible with other engine families without modification. Users building RB26 motors for street or track use will benefit significantly from their enhanced durability. Fitment is fully confirmed for 1989 through 2002 RB26, RB26DE, RB26DETT applications; **2025 fitment is unconfirmed**.
