        A:

        Hi Dennis, glad to help you! This Sealed Power Main Bearing Set (Part No. 4663MA) does not fit your 2005 Chevrolet Tahoe V8 4.8L. We do have an exact fit Main Bearing Set available online for your vehicle and the part number is 7298MA, with standard size. Please enter your vehicle on our website and search for this part to check the fitment.

      Hi, what are the differences between part #s 4663m and 4663ma. I realize one is aluminium. Which is better for a stock to slightly modified engine?
