4340 Chromoly Steel Connecting Rods w/ ARP 2000 Bolts

Achieve your performance goals with IE H-beam connecting rods, designed for strength and reliability in performance builds supporting up to 600 horsepower and torque. Constructed from extra-strong forged 4340 chromoly steel and featuring USA-made ARP 2000 rod bolts, these connecting rods are computer-optimized for specific applications. An optional rifle drilling feature is available to increase wristpin and bushing life through enhanced lubrication, which is highly recommended for street cars driven for extended miles. These 144x20mm connecting rods are compatible with stroker crankshafts and 20mm wrist pin stroker pistons for 2.0L or 2.1L stroker conversions. They are designed to work with VW/Audi engines utilizing factory pistons with 20mm wrist pins on factory non-tapered rods. Engines with tapered rods will require aftermarket 20mm pistons. For higher power builds exceeding 600 horsepower, IE Tuscan I-beam Connecting Rods are recommended. Professional installation and ECU tuning are crucial to ensure the longevity of these connecting rods, as common failure causes include oil starvation, improper tuning, incorrect bearing clearances, or installation errors.
