I am wondering if i can get a different brand 6puck disc release bearing and pilot bushing and alignment tool from another clutch? Is this possible or will i run into clearance issues/non working clutch?

Kupp Racing Stage 3 Copper Ceramic 6-puck Disc (11" , 26 spline)
Release Bearing
Pilot Bushing
Alignment Tool

 

Pilot bushing is defined by engine crank shaft and trans input shaft. Its not real a function of a clutch. Alignment tools are a function of the pilot bearing and the input trans shaft also. Most mechanic have generic alignment tools and do not buy tools per application.

The release bearing has a pressure rating and it height is based on the clutch design. SO if a clutch and pressure plate are not stock then I would think trying a different release bearing would be very risky unless the release bearings manufacturer says it is compatible to that clutch. I would have to have a supper good reason to not use the clutch manufactures release bearing.
