Manley 4340 Turbo tuff I-Beam connecting rods (K20A/K20Z engines)

Manley Pro Series I-beam connecting rods are forged from 4340 aircraft-quality vacuum degassed material. They're fully machined to produce the strongest rods possible. These rods are shot-peened to Mil specs and are 100 percent individually magnafluxed. They feature 7/16 in. ARP cap screws with 12-point heads and your choice of material grade to maximize your needed tensile strength! Manley Pro Series I-beam connecting rods are available in various sizes for a wide range of vehicles and horsepower ranges from 850 - 1,600 HP. Match up your specs, then order an individual rod or a larger set quantity.

We really like the Manley Turbo Tuff I-Beam line from Manley. We have never been able to break one, even over the 1000whp mark, and they hold up well to extended abuse.
They are probably the strongest rod for the money and we suggest them to anyone who wants to sleep well at night knowing they don't have to worry about their rods being a weak link in their high power build.
