Product Details

The ACL Race Series main bearings are engineered for high-performance engines that demand superior durability under extreme conditions. These standard size main bearings feature ACL's advanced tri-metal construction with a steel backing, aluminum-tin alloy intermediate layer, and a specialized polymer overlay that provides excellent load capacity and wear resistance.

Key Features:

  • Race Series construction designed for forced induction and high RPM applications
  • Tri-metal design with polymer overlay for enhanced wear protection
  • Precision manufactured to tight tolerances for optimal oil clearance
  • High crush design ensures proper seating and retention in the main bore
  • Compatible with both petroleum-based and synthetic lubricants
  • Standard (STD) size for original equipment replacement or rebuild

ACL Race Series bearings are the choice of professional engine builders and performance enthusiasts who require bearings that can withstand the rigors of competition use while maintaining precise oil clearances. The polymer overlay provides exceptional embedability of dirt particles and conformability to minor surface imperfections, extending bearing life even under demanding conditions.

I ordered from Autoplicity because they had the lowest price for an exhaust i was looking for. I was kind of iffy at first but then i read all the great reviews. Very fast shipping and delivery! I will be coming back for my next auto needs. Thank you autoplicity for your great prices and customer service!

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available. The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame. So far the service has been great and I look forward to continued great service.

i received item very prompt and for a great price!

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Fast and inexpensive. Thanks.
