ACL Chevrolet V8 305-350-400 Race Series Conrod Bearing Set, STD Sizes, Tri-Metal Steel - 8B663H-001

If you’re diving into the world of high-performance engines, you’ve probably heard of ACL Race Series Engine Bearings. These aren’t just any bearings; they’re crafted with a unique blend of design, metallurgy, and engineering to meet the demands of serious drivers. Built to handle higher RPMs, they’re a solid choice for popular 4, 6, and 8-cylinder setups.

What Makes These Bearings Stand Out?

  • Strong Overlay Plate: The high-strength overlay is thinner, which really boosts fatigue resistance. You want your bearings to last, and this design helps with that.
  • Hardened Steel Backs: All rod bearings feature hardened steel backs. This not only supports the bearing lining but also helps keep everything snug in the housing.
  • Improved Bearing Retention: With increased crush, these bearings stay put, even when the engine’s pushing hard.
  • Heat Transfer: We’ve cut out the flash plating on the backs to enhance heat transfer, ensuring that the bearings can handle the heat of performance driving.
  • Eccentricity Boost: Increased eccentricity helps tackle bore distortion at high RPMs, promoting the formation of hydrodynamic oil films—essential for a smooth ride.
  • Optimized Oil Flow: The 3/4 grooved main bearings maximize the surface area for carrying loads and ensure oil flows smoothly to the conrod bearings.
  • Consistent Tolerances: Tight wall tolerances help maintain the clearances you need for optimal performance.
  • Chamfered Edges: Enlarged ID chamfers on the edges accommodate larger fillet radii on performance crankshafts, so you won’t run into any fitting issues.
