Product Details

The ACL Race Series 4B1912H-STD connecting rod bearings are engineered for high-performance engine builds where durability and precision matter most. These bearings feature ACL's advanced tri-metal construction with a steel backing, lead-bronze intermediate layer, and a proprietary overlay that provides exceptional wear resistance and load-carrying capacity under extreme conditions.

Key Features:

  • Tri-metal design optimized for high RPM and increased cylinder pressures
  • Standard size (STD) for OE crankshaft journals
  • Precision-machined for tight tolerances and consistent oil clearance
  • Enhanced fatigue strength for demanding racing applications
  • Compatible with both synthetic and conventional racing oils

ACL Race Series bearings are the choice of professional engine builders and serious enthusiasts who demand reliability at the track. Each bearing set undergoes rigorous quality control to ensure dimensional accuracy and surface finish meet race-grade specifications.

Got what I ordered and it fits as advertised

I've only clicked the place order button so far.

I would use them again

Great item had no problems.

Happy with everything

Vary good thank you.

Great prices and quick shipping! I will be back!!

Easily had the best prices for the Bilstein shocks I ordered from them. Had a mix up in the delivery but were great at fixing my problem as fast as possible. Will do business with them again!

Great price on my short ram air intake... Actually, best I could find on the Internet. Product shipped the day after the order. Haven't had any problems so far, but it was only shipped just today.

Great prices and fast shipping. It doesn't get any better
