OEM EJ205 75mm stoke P/N 12200AA240. Yep it's a de-stroker. Comes OE with the good crossdrilling for better oiling at high rpm.
Weird coloring is from the nitriding process 3MI Racing had done to it.
It's a beauty, too.
And as promised. A Subaru EJ205 75mm stroke crankshaft next to a Cadillac 500, 4.304" stroke (~109.3mm) crankshaft. Banana for scale.
