King Engine Bearings CR 505XP.026 pMax Black Connecting Rod Bearing Set

The King Engine Bearings CR 505XP.026 is a high-performance connecting rod bearing set engineered for Audi engines using the ABB, ABM, ADP, PP, and RN engine codes. This is an oversized bearing (+0.026"), designed as a precision replacement or performance upgrade for engines that have had their crankshaft journals reground to the corresponding undersize.

These bearings are built using King's pMax Black Trimetal technology — a race-grade construction featuring a steel backing, a copper-lead or aluminum alloy intermediate layer, and a specialized black physical vapor deposition (PVD) overlay. The pMax Black coating dramatically improves wear resistance, reduces friction, and enhances load-carrying capacity compared to OEM-style bearings, making it a preferred choice for high-performance street builds and competition applications.

Key Features:

• pMax Black Trimetal construction — race-proven three-layer bearing design with PVD black overlay
• Oversized: +0.026" (0.66mm) — designed for reground crankshaft journals
• High load capacity — engineered to handle elevated cylinder pressures from forced induction or high-RPM use
• Superior fatigue resistance — withstands the stresses of performance and racing environments
• Enhanced oil retention — optimized surface finish promotes consistent oil film under demanding conditions
• Precision manufactured — tight dimensional tolerances ensure correct clearances and reliable sealing
• Compatible with Audi engine codes: ABB, ABM, ADP, PP, RN
