King Engine Bearings presents king racing line. this new line of XP race bearings combines sport compact and domestic race engine bearings with ground-breaking geometrical and metallurgical features.
I like the HP bearings, but used the XP rod bearings once in my dragster engine. Never a bearing problem before, this time spun two rod bearings, destroyed the bottom end of the engine...Another racer friend of mine was running the XP series mains in his stuff. Same deal, kept spinning mains and killing cranks and blocks. Finally Callies asked to see one of the cranks and bearings. They determined that the bearings were delaminating and grabbing the crank, then spinning....Both he and I have since changed bearings and have had no other issues. Not sure why the XP failed, but they did. The HP series seem to do well though
DONT BUY THIS Bearings ITS AN OVER PRICE PICE OF CRAP, DESTROISI MY CRANK SHAFT AFTER 3000 KM OF USE, IM VERRY ENGRY , DONT USEM SPECIALI ON SUBARU WRX , USE OEM ONLY PARTS.
Lol a Subaru boxer will kill itself even if God’s hair infused components were used, don’t know why people even bother with them STIs Granade themselves almost on stock power let alone a simple remap
