Who can tell me the real difference between ARP's "high-performance" rod bolts and ARP's "Pro-series" rod bolts"?? Besides the $20 price tag, of course....

According to ARP, the ARP2000 material has a 200% higher fatigue strength and 110% the tensile strength of 8740 chrome moly. So basicly, the Pro-series bolts can take about 10% more abuse for twice as long as the high-performance bolts.

How many times have you seen a rod bolt break???

Thanks for the info, it's much appreciated.

First hand, never. I can't even say that I've read about it anywhere, now that I think about it. $20 price difference isn't much at all, so it made me wonder, that's all.

I'm thinking about using ARP rod bolts when I swap the pistons. Until last night, I didn't even know they had 2 options.

Yah I didnt mean to sound like *** if i did.. I have this convo alot with people.. Even on the older style chevy rods with actual bolts I have never seen one break.. It is always something else first.. I could never justify pulling a pan and doing ARP's and risk ,essing with the bearings.. But if it is apart, going to be fresh then yes for 20 or so bucks it could be worth it..

Hey Roger, if you really want to spend some dough on rod bolts check out the Katech's

They almost never break, its usually they stretch a tiny amount and let the rod bearing spin. Either way, rod bolts do nothing to hold more power, only allow more RPMs. IMO, keeping the RPMs down will make a stock short block live longer.

This is true, although the GENIII's generally don't shine down low N/A, and are stouter in stock form than the sbc's of old, in that they can rev higher in stock form without as much concern. Personally, I'd feel fairly confident taking my stock bottom end to 6500 regularly (if my setup called for it), and I know for sure that many here have gone much higher than that without worry
