From my experience on OEM cast and Scat forged cranks the Timken 7109 is flush when installed. The photo on the Summit Racing site is a representation, not the actual part.

I am not familiar with the Tremec, I can only speak to what I have run...Muncie, Autogear and GForce transmissions. The inner diameter of the 7109 is 0.59 in. As you said, put a mike on your input shaft and verify it.

Curious...does Tremec spec a bushing or bearing?

Good luck...keep banging those gears.

Thanks for the response Dan and now that you mentioned it,i don't know....but will find out if bearing or bushing is spec.Good point as I may have otherwise overlooked that !
