I wanted to make a thread and I need peoples help to minimize my searching time and help everyone out when they are looking to buy one. Please correct me if I am wrong I will try to edit it. I am looking to get a new clutch and it is a pain flipping through so many threads and sites. I helps to make an educated descision based on specs from a consolidated list.



I don't really want to get a bunch of opinions or reviews or experiences with brands ect. in this thread, this is purely for facts/specs/info please. You come here, look at the specs, find what you like, narrow it down and THEN you can do a search on the forum or make a thread to check on their reputation, chatter, and other info that could help you decide.

TOB= Throw Out Bearing
