ACL Chevy V8 Race Series Main Bearing Set

Enhance the performance and durability of your classic Chevrolet V8 engine with the ACL Race Series Standard Size Main Bearing Set. Engineered for high-performance applications, this set features a CT-1 coating for reduced friction and improved wear resistance, ensuring your engine runs smoother and lasts longer.

Key Features:

  • Designed for Chevrolet V8 engines (305, 350, 400 cubic inches).
  • Standard size for a precise fit on stock or performance crankshafts.
  • Race Series construction for demanding conditions.
  • Advanced CT-1 coating provides superior lubrication and protection.
  • Reduces friction and heat buildup for optimal power output.
  • Built to withstand high RPMs and extreme loads.

This main bearing set is crucial for maintaining oil pressure and supporting the crankshaft under stress. Whether you're building a street machine, a drag racer, or a track car, ACL bearings deliver the reliability and performance you need. The CT-1 coating is specifically formulated to bond with the bearing surface, creating a low-friction interface that minimizes wear, especially during engine break-in and under high-load conditions. Ensure your engine's core components are protected with top-tier parts.

Invest in the longevity and power of your Chevrolet V8. These ACL bearings are a critical component for any performance engine build, offering peace of mind and race-proven results. Get yours today and feel the difference GGCRACING provides.
