King XP and XPG bearings have a tri-metal construction with substantially higher load capacity compared to bi-metal bearings (such as OEM type) and even competitor's tri-metal products. Increased crush height and elimination of flash coatings improves heat transfer and bearing rentention in the housing. King's Bulls Eye® wall tolerance accuracy is +/- 0.0001", more than twice as accurate as most competitor products. Subaru XPG main bearings have been engineered to address oil starvation issues by changing to a full groove main and eliminating the lug recess. Outperforms all other bearings on the market today.
"X" bearings will provide an additional 0.001" oil clearance compared to standard bearings while "026" bearings will decrease the oil clearance by 0.001".
