King Racing Bearings at JXL Performance

When undertaking a fully forged engine rebuild, the strength of your new pistons and connecting rods is entirely useless if the engine bearings fail under pressure. With decades of dedicated motorsport expertise, King Racing Bearings specializes in high load main and conrod bearings engineered specifically for extreme performance applications. Factory bearings are built for mass market longevity at stock power levels, but once you drastically increase cylinder pressures and push the engine to a higher redline, the OEM bearing shells can easily spin or disintegrate. King Racing provides the ultimate mechanical insurance, ensuring your rotating assembly spins freely and reliably under massive torque loads.

Advanced Tri Metal Conrod and Main Bearings

Whether you refer to them as big end bearings, small end bearings, or main and conrod shells, their fundamental function is identical: preventing catastrophic metal to metal contact between your fast moving crankshaft and connecting rods. King Racing utilizes their advanced pMax Black tri metal construction, combining a high strength copper lead core with a proprietary hardened overlay.

This highly engineered metallurgical composition provides an incredible load capacity while retaining the essential embeddability required to trap microscopic engine debris before it scores the crankshaft journal. Furthermore, King Racing designs their bearings with precise eccentricity and enlarged oil grooves to ensure a constant hydrodynamic oil film is maintained even under extreme thermal stress and high RPM track use.

Essential Rebuild Hardware for EcoBoost and EA888.3 Platforms

Upgrading to King Racing bearings is considered a mandatory step for anyone stripping an engine down for a performance rebuild. They are incredibly popular in the fast Ford tuning scene, where pushing big boost through the factory bottom end frequently exposes the limits of the OEM hardware. We supply precise direct fit bearing kits for the 1.6 EcoBoost found in the Mk7 Fiesta ST, the 2.0 EcoBoost powering the Mk3 Focus ST250, and the high output 2.3 EcoBoost inside the all wheel drive Mk3 Focus RS.

They are equally critical for the VAG tuning market. Engine builders pushing the 2.0 TSI EA888.3 engine beyond Stage 3 power levels in the VW Golf R Mk7, Golf GTI, and Audi S3 heavily rely on King Racing shells to safely support the massive increase in cylinder pressure. Regardless of the platform, dropping in uprated bearings is the smartest investment you can make while the engine block is apart.

JXL Performance supplies genuine King Racing Bearings to engine builders worldwide. Please check individual product listings for accurate availability, as lead times can vary for specific bearing clearances, oversized shells, or special order engine sets.
