ACL Race Series Extra Clearance Main Bearings for GM LS

Achieve the perfect oil clearance for your high-performance engine build with the ACL Race Series Main Bearing Set. Specifically engineered for GM LS Gen III and IV engines, this set provides an extra 0.025mm (0.001") of oil clearance, ideal for engines requiring slightly looser tolerances to maintain oil pressure under extreme heat.

Technical Specifications

  • 270-Degree Oil Groove: Optimized for consistent oil delivery to the crankshaft journals.
  • Extra Clearance: Features an additional 0.001" clearance to accommodate high-performance builds.
  • Race-Grade Construction: Built for durability in high-stress, high-RPM environments.
  • Broad Compatibility: Fits a variety of GM 4.8L, 5.3L, 5.7L, and 6.0L applications, including Cadillac and Chevrolet trucks and SUVs.

These bearings are the preferred choice for engine builders who demand precision and reliability. By allowing for slightly more oil flow, they help manage heat and prevent bearing failure in performance-oriented applications. Ensure your engine's longevity and performance by choosing high-quality components from the experts at GGCRACING.
