Your performance oriented GM vehicle was originally equipped with one of these Pilot Bearings because they eliminate the wear and tear that older style bushings put on your transmission input shaft. When it's time to replace your pilot bearing, make sure you use this highest quality bearing for smoothest engagement, best alignment and longest clutch and transmission life. We suggest replacing your pilot bearing during every clutch swap!
LS1 Camaro & Firebird, LS1 & LS6 Corvette, and LS1 & LS2 GTO all use pilot bearing #14061685. Every other LSx application uses the pilot bearing #12557583.
