Just as critical as the crank are the parts connected to it. Rods experience tremendous forces in a naturally aspirated mill, and it's even worse in a blown engine. For this reason we went with super-strong Lunati 4340 I-beam rods. The fully machined rods are matched to +/- 1.5 grams and utilize ARP cap hardware. After file-fitting the rings, Turn Key mated them to the forged blower pistons, also from Lunati/Wiseco.
