We use a stock 2.4l crankshaft in our race car Any crankshaft you decide to go with is going to need some work. We micropolish and balance the OEM cranks, and check everything on any aftermarket cranks as mentioned above. The benefit to the aftermarket is reduced rotating weight and depending on which crank you choose better oil shedding properties, but in our experience overall strength is not a concern with the OEM units.

 

• Premium Heat Treated Forgings
• Special Teardrop, diagonal oiling features not found in OEM Cranks
• Better Performance at High RPM
• Stress Relieved & Shot Peened
• Nitrided
• Magnafluxed

We sell these for $599 and even offer complimentary balancing on our custom built crank balancing machine

 

Where are those made? $599 certainly seems like a "Not made in America" price.

We are in the process of developing a lightweight, aftermarket crank...but it's motorsports quality made with American steel. Not for the faint of heart or thin of wallet

 

I can't honestly tell you that I don't know where Manley makes them but I know Manley and I know their quality. They had these for a while as they were very thorough with the finishing process.

Manley is a quality product.

 

Understood. I can see how my comment could be misconstrued.

It's just that, as a company who is in the midst of a domestically-produced crankshaft project, $599 wouldn't even cover our bar material LOL
