    FAQ

    What does "Standard Size" mean for this main bearing set?

    Standard size means the bearing shells are dimensioned for a factory, unmachined main journal. It is not for a crankshaft that has been reground undersize.

    What engines does this main bearing set fit?

    ACL lists this set for the Honda/Acura B16, B17, B18, K20, and K24 engine family.

    Which vehicles does this main bearing set fit?

    ACL's fitment data lists the Acura RDX (2007-2012) and TSX (2004-2008); confirm your exact engine code and generation before ordering, since this bearing set spans multiple B- and K-series variants.

    Is this a main bearing set or a rod bearing set?

    This is a main bearing set for the crankshaft's main journals, not the connecting rods.
