King XPG bearings are engineered to take all the boost and RPM your EJ-series can dish out.
Premature bearing failure caused by low oil pressure or oil starvation has plagued high output Subaru EJ-series boxer engines. King's customed engineered XPG race bearings are specifically developed to survive and excel under conditions that cause other bearings to fail.
King has conducted extensive research into the unique oiling circumstances of the Subaru EJ-series engine. The result: a completely re-engineered main bearing set that eliminates oil leakage and increases oil flow to #2 and #3 rod bearings.
King Subaru XPG main and rod bearings are produced in King's AS9100 Aerospace certified production facility. Each bearings is produced to King's exacting Bull's Eye® tolerance and feature King's 0.0005" metallurgically enhanced and hardened XPG performance overlay.
