King Race XP Connecting Rod Bearings - NA/NB Miata

King Race XP connecting rod bearings for the 1.6 and 1.8 engines in the NA and NB Miata, sold as a set of four pairs for built engines with steel crankshafts.

The XP series is King's race bearing. It's a three layer, copper based bearing with King's pMaxBlack overlay, which is hardened to carry more load than a standard overlay.

They're available in standard, STDX (an extra .001" of clearance), +.25, +.26 and +.50 sizes. If you need a size that isn't listed, email me and I'll get you sorted out.
