None of them have been consistent lately.
so are these cranks ground in the USA of offshore?
If offshore, shame on them.
If here, so much for QC.
It isn't if, it's how much.
Problem is nobody wants to pay for a $1000 basic crankshaft, or $3000 for a top of the line crank when you can get an RPM/Eagle/Scat for $200 for a casting and $500 for a forging.
But an Eagle , Probe/RPM crank is good when sized properly
I wouldnt get big on the American crank thing, Took some stuff down to the machine shop and he had sent a Bryant out to get turned on one journal that had too much taper on it
Have seen this with Crower too but it is rare, It can happen to any of them just the cheaper ones seem to be all the time.
The Crower stock GM forging is $1,004.99 and its the same forging as the GM "1182" known as the Crower "Stock Plus"

The Crower "Stock 1182" S38 forging for $939.99

Your typical Crower crank from Jegs runs $1,949.99

The Crower Maxi Light cranks runs $2,304.99

Here is the way I look at it, The customer has two options for say a typical small block
1) pay at least $1500 for a Crower or more for a billet Crower/Bryant
2) pay $875 ($675 + $200 grind) for an Eagle ready to go (Includes turning crank to balance stroke and to true it up) , One thing you have to give Eagle is its a good steel AND their bob weight seems to be on the money
Also, Ohio Crankshaft seems to have issues with taper but the cranks when corrected seem to hold up just fine, Actually seem to look alot like the Eagle forgings, Maybe they are the same forgings. Say a customer wants a light weight crank on a budget, They can get an Ohio 44-45 pound crank for $550 then have it turned to balance the stroke and true it up for $200 and is cheaper than most std cranks and for sure cheaper than light weight cranks
Would I use them in 2500hp engines, No. I would not be scared to use a small block crank from them up to 8000rpm and 600-650hp (That goes for Scat, Eagle, Ohio, Probe, RPM)
Also they (Ohio) dont just take a slice out of the counter weight like some of the cheaper cranks, They actually do a pendelum undercut like Crower
Have also used Scat 4340 crank out of the box, Some to the high side but clearances fine many times with std bearings and no wear issues and you can pick up a Scat for $630 to $650

When it comes to budget cast cranks THE ONLY one I have found to be worth $.02 is Scat , I had a few Eagle that was all over the place and I REFUSE to turn a cast crank
I would have no issue using a Probe crank of thats what your looking at, All cheap cranks have issues that need to be corrected. Mark is honest and tells you where they come from, Not many will do that. Mark knows what he is selling and sells them at a good price

For the people whom want a better crank Mark/Probe Industries offers Scat crankshafts as an upgrade
