KING RACING: Tri-Metal Engineering and Nano-Technology for Extreme Loads
When engine output increases, bearing loads reach critical levels. Standard bearings often deform under hydrodynamic pressure, leading to catastrophic crankshaft failure. For over 60 years, KING RACING has specialized exclusively in engine bearings, developing products that withstand pressures exceeding 10,200 psi where others fail.
ATOMIC-SHOP Ukraine is the official KING RACING supplier. We offer XP and XPC series, the industry standard for Subaru EJ, Mitsubishi 4G63, Toyota 2JZ, and BMW S-series builds dominant at the Chaika Autodrome.
pMax Black™ & pMaxKote™: The KING RACING Advantage
KING RACING stands apart due to material structures and manufacturing precision that lead the industry:
- pMax Black™ (XP Series): A tri-metal structure with a nano-hardened overlay containing 5% more copper. It is 24% stronger than competitors, handling massive cylinder pressures.
- pMaxKote™ (XPC Series): A factory-applied nano-composite polymer coating. Unlike aftermarket coatings, it adds no wall thickness, preserving critical oil clearances while protecting against cavitation and cold-start wear.
- Bull’s Eye Tolerance™: The industry's tightest wall thickness tolerance (+/- 0.0001”), ensuring perfect clearance without "fishing" through multiple sets.
Comparative Table: OEM Bearings vs. KING RACING XP/XPC
| Parameter | OEM Bearings (Stock) | KING RACING (XP/XPC Series) |

| Load Capacity | Up to 8,000 psi | Over 10,200 psi (+24%) |
| Fatigue Resistance | Baseline | 17% higher via pMax Black shield |
| Oil Starvation Protection | Minimal | Superior (via pMaxKote) |
| Dimensional Accuracy | Standard | Bull’s Eye Precision |
| Construction | Aluminum or Copper-lead | Nano-hardened Tri-metal |
FAQ: ATOMIC-SHOP Technical Expertise on KING RACING
Should I choose KING RACING for a daily driver?
While stock AM-series is fine for standard use, the XP series is a vital investment for any Stage 1+ build or track-day car, as it handles thermal spikes and high RPM significantly better.
Does pMaxKote require clearance adjustments?
No. The nano-composite layer is specifically designed to add no thickness, meaning you maintain your calculated oil clearances while gaining advanced anti-friction properties.
