Product Details

The ACL Race Series main bearings are engineered for high-performance and racing applications where durability and reliability under extreme conditions are critical. These bearings feature advanced metallurgy and precise manufacturing tolerances to handle the increased loads and stresses of modified engines.

Key Features:

  • Race Series construction designed for high-performance and competition use
  • 0.25mm undersize for crankshaft regrinding applications
  • Premium tri-metal construction with hardened steel backing
  • Optimized clearances for modified engines and increased RPM
  • Enhanced oil retention properties for superior lubrication
  • Precision manufacturing ensures consistent quality and fit

ACL Race Series bearings are trusted by engine builders and racers worldwide for their consistent performance and durability in demanding applications. The 0.25mm undersize allows proper clearance restoration when crankshafts have been ground to repair journals or achieve specific clearances.

Easy, customer-friendly online shopping. I am satisfied.

I am very pleased with the quickness my product was shipped. I have had problems with other products i have ordered once again Thank You.

Very quick and easy. Thanks

Ordered front & back WeatherTech Digital Fit floormats for my Tacoma, and they arrived 2 days later! Will definitely use again in the future.

Extremely impressed with Autoplicity!!!! I am a very loyal Amazon customer and ALMOST paid a 20% premium on my Thule bike rack to go with old faithful. Very glad I didn't, as I saved $50 and received my product with free shipping FASTER than Amazon Prime!!!

easy to navigate

Great priced items. was WAY under what others wanted. shipped fast also. A+ seller. I will buy from again.

I recently ordered 2 autometer gauges for my truck from Autoplicity. The order arrived 3 days later on my door step. The gauges are beautiful and I cant wait to install them.. Thanks Autoplicity!

I think I had to remind them to ship my item but once I did it shipped the next day. The package had the wrong label on it so I wondered if I got the right item but I did and all is well.
