Look up eagle rods in the FI section of Bimmerforums. They are the same rod, and both are Chinese. Eagle moved production offshore and apparently quality has suffered.

Every rod that looks like that is the exact same. I've spoken to a couple of domestic engine builders who have verified they've held 3 brands of those rods in their hands at once and they were identical in every way. I think Bav Solutions was selling them too at a premium. The engine builder said that he had seen them fail in a 600hp big block be built, I actually saw the thing and it was demolished, but the piston was wedge shaped which imparted a twisting force on the rod, which the builder said was the way that the rod was weakest. He says he knows of them running in dozens of motors without issues though. But anyways, if you'd be comfortable with eagles then you should be comfortable with these, only difference in any rod that looks like that is the bolts supplied, and someone who sells them in quantity might be able to take 50 of them and put together sets that better match in weight, but straight from the factory they are all pretty close. I actually have one set of 130mm's and one set of 135's that I bought along with a friends 100 rod order straight from the factory (unbranded). I should get a decent scale and weigh mine but he grabbed 6 random ones and all were within 3 grams

the rods are probably fine, but I would replace the rod bolts with ARP or something else similar. I know people who've used eagle rods without issues though.

ALL the raw forgings are made in China. Eagle, Scat, and even some Carrillo rods if they look the same, they are. SOME of them are finish machined in the USA some in China, the distributor should Be able to tell you. they are ALL decent rods, pretty light weight, and close tolerance in weight and deminsionally.

unless you get into a Pauter rod or similar you wont do better espically for the price.

the FACTORY rod bolts are OK, but not great. if you are going to the trouble to buy these rods for your engine build, then you should go ahead and pony up the money for either ARP-2000, Raceware, or if you have the big $ Carrillo.

i had looked into the Eagles at 1 time and they only offered 135mm (2.5 ) rods and not the shorter 130mm (ETA /2.7i stroker) rods. that may have changed though.

OP, i was just reading the ad and you should contact the seller FIRST. if you look at thevrod legnth in the description, it lists it as a 5.5" or 139.99mm rod.
stock for everything but the ETA is 135mm. that just a hair under extra 5mm is going to play with your deck height, compression ratio, piston to valve clearence, and piston pin height.

what are your plans motor wise for these rods?
if you are doing a stroker with custom pistons and you have not bought them yet, you can have the wrist pin height adjusted to make up for the longer rod, if not you are going to run into issuesm

maybe it is just a typo in the ad, but i would make sure before you order them.
just a heads up.

hi there

right der affe, this is the wrong size.

I'm looking for lighter rods for my NA M20 build. ( staying 2.5l with stock 9.7 cr pistons).

on the other side, i can buy used stock S50 rods ( us specs ).
