Feature

1.Premium 4340 Forged Steel & H-Beam Design (Built for High-Horsepower)

Engineered from aircraft-quality 4340 chromoly steel with a classic H-beam profile. Fully shot-peened and heat-treated to ensure maximum tensile and compressive strength. Perfect for high-load street and strip (1/4-mile drag) racing applications.

100% packed with authentic ARP 2000 12-point bolts boasting a 220,000 psi yield strength. Also offers an optional upgrade to 260,000 psi ARP L19 fasteners, completely eliminating rod-cap separation at extreme high-RPM loads.

3.Factory-Balanced within ±1.0 Grams (Engineered for High-RPM Stability)

Every single set undergoes dynamic balancing at the factory to maintain a strict weight variance of less than 1.0 grams per set. This precise QC standard ensures smooth power delivery and minimizes harmful harmonic vibrations at high RPMs.

4.Triple Non-Destructive Testing & Floating Pin Style (Race Ready)

100% magnafluxed, X-rayed, and ultrasonically tested to guarantee zero internal flaws or cracks. Features a high-lubrication bronze bushing for floating-style wrist pins, making it fully compatible with premium aftermarket forged pistons.
