I know the OEM unit is a Koyo. But, a lot of clutch kit manufactures include NSK TOBs with their kits.
The Koyo looks a lot more beefy then the NSK. Case is about the same diameter but looks thicker in height/depth. Like there would be bigger bearings inside.
Searching, I have only heard ancillary reports on both brands performance(My TOB failed so it must be the Koyo/NSK's fault).
Side note, I was always told KA and SR TOBs were different. But I have a couple SR and KA TOBs that came with their respective motorsets and they both have the same Koyo part numbers.
