3R80-35 – Center Support Bearing – Buick Application – 1.574″ ID – Notes Buick, Bearing not included

The 3R80-35 Center Support Bearing plays a vital role in maintaining the integrity of the driveshaft in various Buick models. Specifically designed for 1965-1968 Buick Electra, LeSabre, and Wildcat, as well as the 1962-1963 Buick Special and Skylark, this component is engineered to support a two-piece driveshaft at its midpoint. This setup is essential for reducing driveline whip and ensuring proper alignment under load.

One of the key specifications of the 3R80-35 is its 1.574″ bearing ID, which is critical for fitting the compatible internal bearing, the 3R80-15. It’s important to note that this product is a housing only; the bearing is not included. The design of the center support bearing allows for effective vibration isolation, which is crucial for maintaining a smooth ride. A hardened or collapsed rubber isolator can lead to driveline vibrations, particularly at highway speeds, which can be detrimental to performance.
