Clutch Pilot Bearing

The GM 12557583 is a manual transmission clutch pilot bearing designed with a larger outer diameter (OD) for specific applications. This roller pilot bearing, also known by ACDelco part number CT1082, measures 1.705" OD, 0.590" ID, and has a thickness of 0.510". Its primary function is to support the transmission input shaft when the clutch is disengaged, ensuring proper operation and preventing potential damage. This particular pilot bearing is identified as the "larger design OD bearing" and is specifically noted for use in C6 Corvette, 1st & 2nd generation CTS-V, and 5th generation Camaro applications. It is also compatible with all GM LS 1997-2019 Engines, including LS1, LS2, LS3, LS6, LS7, LS9, LSA, and engine displacements such as 4.8L, 5.3L, 6.0L, and 6.2L. It is crucial to use the correct pilot bearing for your engine and transmission to avoid permanent damage. The manufacturer recommends verifying year, model, and application details with their Performance Sales Team if unsure about fitment.
