When you're rebuilding a Buick V6 engine, especially for a 1975-1977 Buick Regal, getting the right main bearings is crucial for long-term reliability. These ACL main bearings are built to handle the demands of your engine, ensuring smooth operation and proper crankshaft support. They are designed to fit Buick V6 engines with displacements from 181ci up to 252ci, covering a wide range of model years from 1964 to 1990, including specific applications like the 3.8L (231ci) Type C and the 3800 engines.

ACL uses a specialized overlay material that's known for its durability and ability to withstand the high pressures found in the main bearing journals. This material helps to reduce friction and wear, which is essential for extending the life of your engine rebuild. They are manufactured to meet or exceed OEM specifications, meaning you get a part that's made to perform reliably in your specific application. If you're working on a 1975-1977 Regal, a 1988-1990 Riviera, a 1978-1979 Skylark, or even a 1966-1967 Jeepster with the appropriate V6, these bearings are a solid choice.

When installing these bearings, make sure your crankshaft journals are clean and within factory specifications for size and finish. Proper lubrication during assembly is also key to ensuring these bearings perform as intended right from the start.
