Product Details

The ACL Race Series 4B8351H-STD connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature ACL's advanced metallurgy and tri-metal construction designed to withstand extreme loads, high RPM operation, and elevated temperatures common in competition engines.

Key Features:

  • Tri-metal construction with high-strength steel backing for maximum durability
  • Premium bearing material optimized for race conditions and aggressive cam profiles
  • Precision tolerances ensure proper oil clearance and consistent performance
  • Standard size (STD) for factory crankshaft journals
  • Enhanced embedability to protect against debris contamination
  • Improved fatigue resistance for extended service life under racing conditions

ACL Race Series bearings are a popular choice among engine builders and racers who demand reliable performance under extreme conditions. These bearings are designed to maintain proper oil film thickness and prevent metal-to-metal contact even during high-load situations.

Excellent Website to Shop From and Excellent Email and Shipping imformation received promptly and prices are the best on the internet. Will definitely shop again and refer to my friends.

Excellent store! I found the fuel pump that I was looking for right away and for almost half the cost of competitors. Better yet, the order shipped out that night! I make a lot of online purchases and have grown accustomed to the normal lengthy process but this store knows what they're doing! Great experience overall and I will be sure to buy from them again and spread the word!

Lowest price we could find. Fast shipping. Would do business with them again.

Great prices. Fast Shipping. I would definitely do business again.

Fast shipping , product just as described, and quality product.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!

Best place to find good products for cheap. I just got a jet programmer for almost $100 below the normal price. I also appreciate the fact that they gave me a call to make sure I was the one ordering.
