3R80-60 – Center Support Bearing – Gm Application – 1.378″ ID – 2.375″ Center Bearing To Base

3R80-60 is a Center Support Bearing specifically designed for GM applications, particularly Chevrolet and GMC 1/2 ton pickup trucks from 1999 to 2007. This bearing plays a crucial role in supporting a two-piece driveshaft at its midpoint, maintaining proper alignment and minimizing driveline whip. A key feature of the 3R80-60 is its 1.378″ bearing ID, which is essential for ensuring a snug fit on the driveshaft.

When diagnosing driveline issues, if you notice vibrations at highway speeds or hear bearing noise, the center support bearing is often the first component to check. A worn or collapsed rubber isolator can lead to increased vibration, which can be traced back to this part. The center-to-base height of 2.375″ is critical; it helps maintain the correct operating angle of the driveshaft, preventing further complications.

• 1.378″ Bearing ID for secure fit
• 2.375″ Center Bearing To Base for correct alignment
• 6.625″ Center To Center Of Mount Holes for easy installation
• Enclosed type bracket with M10-1.5 studs for secure mounting
• Fits Chevrolet GMC 1/2 ton pickup trucks (1999-2007)

During installation, ensure that you do not pre-load the rubber isolator and align the mounting bracket before tightening. This will help avoid unnecessary stress on the bearing and prolong its lifespan. The 3R80-60 is a reliable choice to restore proper function and eliminate driveline vibrations.
