High-Performance ACL Rod Bearings for VW/Audi Engines

When rebuilding your 1781cc or 1984cc engine, precision is non-negotiable. This ACL Race Series 0.25 oversized rod bearing set is engineered to provide superior load-carrying capacity and durability under high-stress conditions. Designed specifically for performance-oriented VW and Audi applications, these bearings feature a tri-metal construction that balances hardness and conformability.

Key Technical Features

• Oversized Fitment: Specifically machined for 0.25mm undersized crankshaft journals.
• Tri-Metal Design: Hardened steel backing with a copper-lead alloy lining for maximum fatigue resistance.
• Precision Tolerances: Engineered for consistent oil film thickness and reduced friction.
• Broad Compatibility: Fits a wide range of Audi 4000, A4, TT, and Volkswagen Beetle, Cabrio, and Golf models.

Whether you are building a street-performance engine or a track-ready machine, choosing the right bearing clearance is critical for longevity. These ACL bearings offer the reliability required for high-RPM operation and increased power outputs. Ensure your crankshaft is properly machined to accept the 0.25 oversized dimensions before installation to achieve optimal oil pressure and thermal management. Trust your engine build to the industry-leading quality found at GGCRACING.
