    Will It Fit Your Vehicle?

    This should fit your vehicle as long as you have a k-series engine.

    Fitment Notes: Not for K20A3 Cranks


    K Series Parts has used ACL bearings in almost every k-series motor we have built. We highly recommend them for any K20 and K24 engine build!

    The ACL High Performance Standard thickness is -0.001" or -0.025mm smaller than their standard bearing to allow extra oil.
