Speedmaster PCE274.1079 I-Beam Race Connecting Rods 5.315" Ford 302 4340 Bronze Bush

The Speedmaster PCE274.1079 is a set of I-beam race connecting rods engineered for Ford 302 engines. These lightweight (LW) connecting rods feature precision-machined 4340 steel construction with bronze bushings, designed to deliver reliable performance in high-RPM racing and performance engine builds. The I-beam profile offers excellent strength-to-weight ratio, critical for maximizing horsepower and throttle response while maintaining structural integrity under extreme acceleration loads.

Built to the exacting specifications of serious engine builders and racers, these rods feature a 5.315" center-to-center length and 2.123" big-end bore with .912" small-end diameter, ensuring proper fitment and clearance in your 302 block. The bronze bushing material provides durability and reduced friction, key factors in extending engine life and maintaining consistent performance through repeated power cycles. Ideal for street-strip dual-purpose vehicles, circle track racing, or dedicated race engines where every fraction of weight and every increment of reliability matters.

Key Features & Benefits
