Details:

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. King Engine Bearings met the challenge with the XP high-performance bearings series. The XP series is a line of bearings with advanced metallurgical and geometric technologies that meet extreme performance loads. It was developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.

The unique pMax Black overlays and a tri-metal structure are 24% harder than conventional race bearings. These bearings receive a factory-applied nano-composite coating, pMaxKote. Acting as the fourth layer over the pMax Black, this coating enhances wear resistance. It safeguards the bearings during periods of marginal lubrication, all without altering the original wall thickness dimensions. The result is race bearings designed to withstand the highest loads and RPMs generated by top-tier competition engines.

Since its establishment in 1960, King Engine Bearings has been dedicated to supplying the highest quality bearings in the market, specializing in engine bearings. The product range spans various engine types, including those for automobiles, light-duty and heavy-duty trucks, marine, aviation, standby power, and more. Rigorous quality control checkpoints during production guarantee only the highest quality bearings.

Features:

• 15% - 30% greater load capacity than traditional bearings

• The SecureBond unique adhesion process for superior stability between the top and intermediate layers

• 0.0005" metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue

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