Speedfactory Forged Steel H Beam Connecting Rods - K20

We are proud to introduce the new SpeedFactory Racing K20 A/Z H-beam connecting rods! These rods are ideally suited to K20 A/Z engine builds (K20, K20A2, K20Z1, K20Z3) to the 900+HP range and offer high strength and quality at an affordable price. Our design is strong enough for almost any K20 A/Z build. The 2-piece forged 4340 chromoly construction provides outstanding strength and quality. Each rod is heat-treated, magnafluxed, CNC machined, and shot-peened to stress-relieve the metal. The rods have precision alignment dowels to positively locate the rod cap, maintain big end bore size, and eliminate cap walk. They feature bronze alloy pin bushings for floating wrist pins and come standard with 220,000 psi rated 3/8” ARP2000 rod bolts. Instructions and ARP Lube are included. NOTE: Does not fit K20A3 Features: - Forged SAE 4340 Chromoly Steel - 100% CNC machined - Precision rod cap alignment dowels - Bronze alloy pin bushings w/dual offset oiling holes for superior lubrication - Pin end fits most aftermarket pistons w/out additional machining - Not compatible with OEM style pistons - Magnafluxed - Multi-stage heat treated - Shot peened to relieve stress - Each set balanced to +/- 1 gram - Laser etched SFR logo - 900+hp rated   Specifications: Engine: Honda/Acura K20 A/Z (Does not fit K20A3) Material: Forged 4340 chromoly Bolts: 3/8” ARP2000 Weight: 499 grams Center to Center Length: 138.98mm – 5.472” Pin End Bore: 22.0mm - 0.866” Pin End Width: 19.8mm – 0.780” Big End Bore: 51mm – 2.008” Big End Width: 19.8mm – 0.780”
