Connecting Rods
Crown's connecting rod lineup is intentionally simple.
Choose the rod based on the demands of the engine rather than navigating dozens of nearly identical options.
STREET / STRIP
4340 Forged Steel | SP8740 Fasteners
The Crown Street / Strip Rod is our entry into serious performance, combining a forged 4340 H-beam with SP8740 fasteners for street-driven and weekend performance applications. It is designed for builders who want a substantial upgrade from factory connecting rods without paying for race-level hardware they may not need.
RACE
4340 Forged Steel | ARP 8740 Standard | ARP2000 Optional
The Crown Race Rod steps up the H-beam platform with genuine ARP 8740 fasteners for more demanding naturally aspirated and boosted combinations. Builders wanting additional fastener capability can specify genuine ARP2000 bolts while retaining the proven 4340 H-beam architecture.
PRO RACE
A300 Steel | Heavy-Duty I-Beam | ARP2000 Standard
The Crown PRO Race Rod is our flagship connecting rod, built around a heavy-duty I-beam architecture, high-strength A300 steel, and genuine ARP2000 fasteners. It is intended for serious competition engines where high cylinder pressure, RPM, and component capability take priority over entry-level cost.
