  Scat has been manufacturing and distributing connecting rods, crankshafts, and engine components for more than fifty years. The tradition continues to this day with a 42,000 sq/ft facility in Redondo Beach, California. Quality is the first step in all Scat products... skilled craftsmen, superior materials, innovation, and dedication create the absolute best parts for you.

Scat’s 4340 Forged Pro Series I-Beam connecting rods deliver a critical upgrade for builders seeking dependable strength without unnecessary bulk. Crafted from high-strength 4340 chromoly steel, they’re engineered to resist fatigue and bending—even under sustained high-RPM performance use. The rods are shot-peened and polished to eliminate stress risers, further enhancing durability and reliability in demanding builds.

One of their standout features is the single rib cap design, which boosts bearing support while maintaining a slim, efficient cross-section—a smart balance between strength and weight. The cap is doweled to guard against cap walk, and the beam geometry is profiled to accommodate stroker applications where clearance is tight.

To secure the fasteners, Scat includes heavy-duty ARP 2000 or 8740 series 7/16″ bolts—depending on the application—providing additional clamping reserve beyond typical high-performance requirements. Each set is precision balanced to tight tolerances (often within ±2 grams) to ensure smooth operation and reduced vibration throughout the RPM band.

These rods are ideal for street/strip builds and bracket engines where strength, economy, and longevity all matter. They’re capable of supporting power levels above 600 HP in many small-block setups when matched with proper components.

If you need performance-grade internals you can rely on, these scat pro series rods offer a durable solution without excessive weight. As true scat i beam rods, they bring race-level technology to your build at a realistic value. Whether you're upgrading your existing bottom end or building a high-output engine from the ground up, these scat rods make a compelling foundation you can trust.
