Product Details

The ACL Race Series main bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature ACL's advanced tri-metal construction with a steel backing, aluminum-tin intermediate layer, and a proprietary polymer overlay for superior load capacity and wear resistance under extreme conditions.

Key Features:

  • .025" undersize for crankshaft journals that have been machined or require fitment adjustment
  • Tri-metal construction with high-strength steel backing for maximum support
  • Proprietary polymer overlay reduces friction and improves oil retention
  • Engineered for high RPM applications and increased cylinder pressures
  • Enhanced crush relief and wall thickness for racing applications
  • Compatible with synthetic and conventional racing oils

ACL Race Series bearings are the choice of professional engine builders and serious enthusiasts who demand precision fitment and reliability in demanding motorsports environments. Each bearing set is manufactured to strict tolerances to ensure proper oil clearance and optimal performance.

Excellent!

I returned back the order I received is wrong size with day3/7/19 with tracking # 9400111699000451141826. And I want to cridetd to my account please.

Fast shipping. Good price.

Good Price and Hoping recieved my items quick. Thank You

Shipping notification delayed several days after I called - great otherwise.

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

I felt I had to double check with Centric site as your brake shoe compatiblity chart didn't seem to go past 1956.

Everything went good, order shipped out the next day. The prices were good but the shipping cost was way to high $25 dollars for 2 head gaskets and some bolts oil pan bolts.

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>
