These forged H-beam connecting rods from SpeedFactory Racing are suitable for high horsepower street and track B-series builds. They are rated for over 225HP per cylinder, or 900+HP total, while remaining lighter than many other H-beam rods on the market. An excellent option for a fully built B18 or B20 bottom-end without breaking the bank. 

Forged 4340 chromoly construction provides outstanding durability. Each rod is CNC machined, magnafluxed, heat treated, and shot-peened to relieve stress in the metal. Precision alignment dowels are used to correctly locate the rod caps, 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. 

Not suitable for OEM style pistons; works with most aftermarket pistons without machining.  

Instructions and ARP Lube are included.
