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
