High-Performance Extra Clearance Bearings

For high-RPM engine builds, oil clearance is critical. The ACL Race Series extra clearance main bearing set provides the slightly increased gap necessary to maintain high oil flow and pressure in performance VW/Audi 1781cc and 1984cc engines. These bearings are designed to prevent oil starvation at high engine speeds.

Technical Advantages

• Clearance: Extra oil clearance for high-RPM
• Application: VW/Audi 1.8L and 2.0L
• Design: Tri-metal construction for maximum load
• Lubrication: Optimized for high-volume oil systems
• Fitment: Standard housing diameter with reduced shell thickness

When you increase the power output of your engine, the demand on the lubrication system increases exponentially. These extra clearance bearings allow for better oil circulation, which helps carry heat away from the crankshaft journals more effectively. By providing a slightly larger gap, these bearings reduce the risk of bearing seizure during extreme performance conditions. The #4 journal is configured with dual-sided oil grooves to ensure that the center of the engine remains well-lubricated under heavy load. These are the preferred choice for tuners and engine builders who demand reliability from their high-performance VW or Audi builds.
