Arp rod bolt replacement ?
Arp rod bolt replacement ? i have a 2003 lq4 6.0 i'm putting my stang .. and i want to replace the rod bolts with arp's... but not get into a rebuild motor looks good , just want to have the sercurity they are there .. if doing so.. what is the proper way of doing this ? take out 1 bolt at a time then tourque them together ? not to distrub the rod caps , or if i wanted to check the rod bearings for wear .. would this open a can of worms ? ...
i believe one bolt at a time is the "proper" way to do it.
checking the bearings would probably require a much more intensive process. and if you'e going THAT far...may as well replace the bearings.

From what I understand the factory bolts from 1999 on were supposed to be good up to about 450hp. The faster you spin it the more likely they will fail. If you arent going to spin it up I wouldn't replace them. Their is a guy on TeamChevelle with a stang transplant that runs 10.50's with a l92 head/cam swap, and I don't think he changed anything internally.
well ALOT of guys are running the stock bolts....97/98 or newer.
doesn't mean it won't be peace of mind to replace them.
with the motor out it should be no problem at all. flip it over, remove the pan and swap one at a time.

And expensive......Just swap the ARPs however you want and follow torque procedure. The caps cant misalign bc they fit together like a puzzle piece.

It seems hit or miss, SOMETIMES the arp rod bolt pull the big end of the rod out of round. which will very quickly spin a rod bearing. The proper way to do rod bolts on LS's is to remove the rod install the bolts and hone the big end so that it is perfectly round. The stock caps are cracked so you can't miss align them so weather or not you do 1 bolt at a time or 2 at a time that won't affect weather or not the big end is still in spec as far as roundness goes. unless you are going to spin it hard or spray it often I'd leave the stock bolts in there
the reason for the one at a time deal is some are carelees or just dont know
the ls has a cracked cap rod. witch means you have to get the cap reseasted in the fractures when it was cracked apart and sized. not that hard just need to mke sure it is right doing 1 at a time takes this out of play
these rods are less likely to go out of round than the old school rods just due to that.
change them and be done. or if it is 2000 or newer and you dont spin over 7k leave them alone
rod bolts and rwhp have nothing to do with each other there is as much bad info on this site as good.
rod bolts keep the rod hooked to the crank while letting off under power the rod is being mashed onto the crank. at that point the bolts dont matter just show the lack of understanding most have

RPM and Heavy recipricating parts is what Kills Rod Bolts fwiw, HP doesn't sqat But usually Horsepower and RPM come hand in Hand so many think its horsepower killing r-bolts but That is incorrect its the RPM
