Horsepower Is Irrelevant (To Your Rod Bolts)

When can you reuse a rod bolt, and does horsepower (or more usefully cylinder pressure) matter when it comes to selecting the correct rod bolt material?

Chris Raschke of ARP runs us through the ins and outs of these questions and more including some insight into the materials ARP commonly use for rod bolts, being 8740 ally chrome moly (aka chromoly) steel, ARP2000, L19, Custom Age 625+, MP-35 etc

When is it OK to reuse an ARP rod bolt, what is hydrogen embrittlement/stress corrosion and why is it important to use a known lubricant on your rod bolts rather than just some random oil off the shelf are all topics Chris helps us to understand via the ARP Fasteners stand at the SEMA Show

While gloves are worn by many engine builders by choice, they are not strictly required save for some specific materials which is also discussed in relation to the likes of custom age 625+ and L19 etc
