King Racing Coated Main Bearings (Toyota 1JZ / 2JZ) | MB7084XPCSTDX
The Ultimate Main Bearing Setup for High-Horsepower JZ Engines
If you are pushing big boost through a Toyota 1JZ or 2JZ, factory-spec bearings won't last. The King MB7084XPCSTDX main bearing set is engineered specifically for high-stress, high-horsepower JZ builds. This premium tri-metal set combines extreme load capacity with a specialized polymer coating to protect your crankshaft under severe racing conditions.
pMaxKote™ Factory Polymer Coating
The "XPC" line features King’s advanced pMaxKote™ polymer overlay. This thermal barrier is applied directly at the factory without altering oil clearances.
- Dry Start Protection: Eliminates metal-to-metal contact during cold starts or sudden oil pressure drops.
- Wear & Cavitation Resistance: Adds a highly durable layer that resists erosion, manages heat, and extends overall engine life.
Built-In Extra Clearance (.001" STDX)
The STDX designation means these bearings are manufactured with .001" (0.025mm) of extra built-in oil clearance. This eliminates the need to polish cranks or modify housings to get the loose, safe clearances required for high-RPM racing. It allows for optimized oil flow and a thicker hydrodynamic oil film, making it perfect for builds running heavy racing oils.
Unmatched Precision and Load Capacity
Built on King’s XP tri-metal platform, these bearings handle up to 24% more load than standard options. Thanks to King’s Bull’s Eye Tolerance technology, shell-to-shell wall thickness varies by less than 0.0001”. You get perfectly consistent clearance across every single main journal.
