When building a high-output 4G63 or 4G64 engine, the bottom end is the foundation of your success. These Clevite H-Series performance rod bearings are engineered for enthusiasts who demand reliability in medium to high RPM ranges. Featuring a hardened steel back and a specialized thin overlay, these bearings provide the structural integrity needed for high-load applications.

Technical Specifications & Benefits

• Medium Eccentricity: Optimized for improved oil film formation during high-RPM operation.
• High Crush: Ensures maximum retention in the connecting rod bore, preventing spinning under extreme stress.
• Flash-Plating Free: Manufactured without flash plating to promote superior seating and consistent clearances.
• Oversize Fillet Compatibility: Designed to work seamlessly with crankshafts featuring larger fillets, common in performance builds.

Whether you are restoring a classic DSM or building a track-ready Mitsubishi, these bearings offer the precision tolerances required for long-term durability. By utilizing a high-strength material composition, Clevite ensures that your rotating assembly can handle the increased cylinder pressures of performance tuning. These bearings are the preferred choice for engine builders who refuse to compromise on quality. For all your engine internal needs, trust the selection at GGCRACING.
