Default Ebay Crankshaft

Exactly what your thinking. http://www.ebay.com/itm/Chevy-LS-4340-Forged-Crankshaft-ST-4-100-M-LS-RJ-2-1-MRL-6-098-RMS-1Pc-Bal-Int-/171221651130?pt=Motors_Car_Truck_Parts_Accessories&hash=item27dd9b0eba&vxp=mtr
Says it's forged and 4.1 stroke. Now I've already done a little research and the ebay'er is Procomp. Now I know a lot have had success with the Procomp headstuds but a lot are upset about the heads they made. Has anyone dealt with or know anything about these cranks? Heck of a knock off in price at 459.99.

But as Billy Mayes use to say. "BUT WAIT! THERE'S MORE!"

They also offer a cast steel "non-forged" crank in the same 4.1 stroke for 159.99.

Now I did a little more looking into this and found a company named Sag Performance that claim they use these cranks "Chinese Knockoff" as they call them all the time over a 3 year period and have only had one break and it was a 600hp + 4400lb Cady Cts-v with 500 hrs run time. "so they claim". They're selling these cranks for 650 and say they come in 4' 4.1' and 4.125'.
They also claim that these cranks are the same as Eagle just copied by a Chinese company.

So again does anyone know anything about these? Or know anyone who's run them?

I'd hate to take the time to build a stroker motor with a 4.125 stroke crank and then be worried the whole time thinking I was going to break my crank.

A lot of the cheap Chinese cranks are sold cheap for a reason..that cost will jump up once you go to balance it and it takes more work/heavy metal to balance. Stick with someone reputable, definitely don’t want to regret it later.

Grab a K1 crank... 799 from Brian Tooley's shop.

They are Chinese 4340 forgings, but machined and QC'd here in the states (like Compstar). Folks seem to like them and their quality. Available in 4.000" and 4.100" stroke configurations at that price.

If anyone has any questions in regards to Eagle cranks please call us at 662-796-7373. The crank you are looking at is not," the same as" an eagle crank. We do not sell a cast LS crank. Also, just so you know we do not private label crankshafts for other companies.

Oh I have no intention of buying one of these. I have a Lunati slated to go into my block. I was just wondering if anyone had seen these or knew anyone running them. But I'm glad to see Eagle in here because you may want to look into this company claiming these cranks are Eagle knockoff designs.

I'm surprised there's a 4.10" stroke cast crank.
