Why Eagle?

The Eagle SIR5400FB I-Beam Connecting Rods are crafted to dominate in every aspect:

Superior Strength:

Forged from premium 5140 steel, these rods offer up to 50% greater tensile strength than stock rods, supporting up to 750 horsepower with ease. Perfect for high-RPM street and race applications.

Uncompromising Precision:

CNC-machined with tolerances of +/- 0.0001 inches, ensuring flawless fitment and optimal performance under extreme conditions.

Lightweight Design:

At an advertised weight of 550 grams per rod, the SIR5400FB reduces rotating mass, minimizing stress on your crankshaft and bearings for extended engine life.

Enhanced Durability:

Each rod is X-rayed, sonic-tested, magnafluxed, and shot-peened to eliminate stress risers and ensure fatigue resistance, even in the most demanding environments.

Stroker-Friendly:

Profiled for clearance in 302, 331, and 347 stroker engines, these rods are ready for your high-performance build without modification.

Best Value:

Outperforms H-beam and premium 4340 steel rods at a fraction of the cost, delivering race-winning performance for budget-conscious builders.

No other connecting rod matches the SIR5400FB’s blend of strength, precision, and affordability, making it the definitive choice for Ford Small Block enthusiasts.
