King XPG Racing Series Main Bearings for Rear Thrust Position EJ Engines .002 Larger OD Extra Clearance Hardware The smaller and lighter retainer

The smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control

Mains are 1/2 grooved for uncompromised lower shell load capacity

bolts and washers

The ring gear teeth are integrated onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and has the possibility of separating from the flywheel due to the different expansion coefficients of aluminum versus steel

King XPG Racing Series Main Bearings for Rear Thrust Position EJ Engines .002 Larger OD Extra Clearance Hardware The smaller and lighter retainerRear Thrust (#5 Position) . 001 extra clearance . 002 Larger OD (For Line Honed Blocks Etc) Successful race engine builders are constantly pushing the limits of load capacity to new levels. Race bearings today inevitably need to match these demands with more competitive bearings. At King Racing we met the challenge with the XP high performance bearings series. The XP series is a line of bearings with advanced metallurgical and geometric technologies
