I am replacing the ARP rod bolts on a set of manly rods.

I have read that some have experienced problems with the ARP2000 replacements. Any truth?

the L19's are claimed to be a better fastener. If these were used would they require the big end resized?

Last year I lost a brand new motor due to some bad ARP 2000 rod bolts. Lost three rods on very first burn out. Motor was built by the best and ran on dyno. I don't think that this is common to ARP but it was determined to be weak bolts in my case. I would not be afraid to run them again. Matter of fact engine builder used ARP 2000 when he repaired motor. I really think I was just the unlucky one to get a few bolts that were not treated correct.

We had a builder near me that broke the head off just torquing the bolt up only to fine out the chinese rods needed to be spot faced and it was not the bolts fault!!

have heard for years the L19 bolt is a great fastner! only prob is something to do with they have to be handled with rubber gloves.i cant believe that the oils in your fingers would cause a prob, but thats what these message boards over the years say. also must use solvents to wash, no hot dip/spray tanks....i really dont know more than that, sorry. but when i put my engine together i ordered the L19 and my junk still works

I would reuse them in my opinion. At most buy a new set of ARP 2000 bolts

How did they even hone the rods then Carl? The manufacture would have to TQ the bolts down before they did any machining!

You can only cycle them so many times. Mine have been on and off twice, time for new.
Really? With the old ARP lube you had to cycle the bolts about 8 times JUST to get them to TQ properly.....:confused:

At the place I used to work for the rods came finished with no bolts. Just take out of Chinese box, insert bolts, rebox. Although the "street" rods did come with horrible ARP knockoffs that streched like a rubber band.

The Chinese h-beam rods on their price sheet were around $13-$14/rod so you were spending more on bolts than rods lol.

Just for shits n giggles every now and then i'd torque up a set just to see where the big ends were and most of the time they were pretty good on size, boss didn't like me doing that because he said I was wasting time because they are supposed to be finished to size, quit screwing around and just put them in the box.
Guy was a serious D-bag.
