Product Details

The ACL Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature advanced metallurgy and coating technology designed to withstand extreme loads, high RPM operation, and elevated temperatures found in competition engines.

Key Features:

  • Race Series construction for maximum durability under extreme conditions
  • -.25mm undersize for crankshaft journal machining and rebuilding
  • Premium tri-metal construction with performance coating
  • Engineered for high load capacity and fatigue resistance
  • Precise dimensional tolerances for optimal oil clearance
  • Suitable for street performance and full competition builds

ACL Race Series bearings are a proven choice among engine builders and racers who demand reliability and performance. The undersize designation allows for proper fitment on reground or undersized crankshaft journals, making these ideal for engine rebuilding and performance machining applications.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best prices online for a locker and pretty fast shipping too!

I have place my order on line and I am very satisfied with your services , I wil recommend every one to purchase from you

Awesome place to get parts from. Went looking all over the city of houston to find a certain light everyone was sold out tried online two "Huge chain name" places were also sold out. Stumbled on Autoplicity and they had just what I needed!

Lowest price online. Shipped about an hour after I placed the order. Many payment options make it easy. Haven't been able to track my package but I'm assuming its too soon, I'll try again soon.
