The XP Tri-Metal Racing Series

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 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.

King Racing’s XP series features pMax Black™, a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing.  pMax Black™ together with the XP geometric features are the ideal combination for performance racing.

Metal Structure : Tri-metal copper lead.

Race Type: Circle track, Off-road, off-shore, others that require steel crankshafts.

Engine requirements: High load – Long Duration.

HIGHER LOAD CAPACITY
The only bearing with load capacity of 17,000psi in the intermediate and 10,200psi in the overlay
BETTER FATIGUE RESISTANCE
The only bearing that goes through a hardening process creating a black fatigue resistance shield, which makes the overlay 24% stronger than any other bearing (11.5hv vs 14.5hv)
MORE ACCURACY
The only bearings with wall thickness variation of ±.0001” as a standard in comparison to ±0.00025”.
MORE CONSISTENCY
from bearing to bearing, requiring less adjustment during assembly
ONE SET FITMENT
The only bearings that don’t require you to buy multiple sets to achieve desired oil clearance
