Product Details

The ACL Bearings 8B8091H-.25 Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature ACL's advanced Race Series construction, designed to withstand the extreme loads and temperatures encountered in competition engines.

Key Features:

  • Race Series performance-grade construction for high-stress applications
  • 0.25mm (.010") undersize for crankshaft journal machining and rebuilds
  • Premium tri-metal bearing material with enhanced fatigue resistance
  • Optimized clearances for high-RPM operation and aggressive camshaft profiles
  • Compatible with modern synthetic racing oils
  • Precision manufacturing for consistent bearing crush and oil clearance

ACL Race Series bearings are a trusted choice among engine builders and racers who demand maximum reliability under extreme conditions. The undersize specification allows for proper fitment on machined crankshafts, making these ideal for performance rebuilds and race engine preparation.

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.

PIAA stuff ships slow but good prices

Great shopping experience have ordered from autoplicity several times. Only downfall is they don't offer free shipping but usually the price plus shipping is less than anywhere else.

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.
