Many of our GM clutch kits come with two different pilot bearings - if, for any reason, you're confused or unsure with a swap application or a simple installation feel free to reach out to us and we'll gladly confirm which to use. 

The small pilot bearing fits 1998-2002 FBODY, 2004-2006 Pontiac GTO, and C5 Corvettes. 

The large pilot bearing fits C6 & C7 Corvettes, Gen 1 & Gen 2 CTS-V's, Gen 5 & Gen 6 Camaros, SS Sedans, SSR's, and Pontiac G8 GXP's.
