Key Features:

  • Race Series construction with enhanced material composition for extreme operating conditions
  • 0.25mm undersize for machined crankshafts or precise clearance requirements
  • Tri-metal design with high-strength steel backing for maximum durability
  • Optimized bearing profile for improved oil flow and reduced friction

ACL bearings are manufactured to strict tolerances and undergo rigorous quality control testing. The Race Series is specifically developed for competitive motorsports and demanding performance builds where bearing failure is not an option.

Not only did they have an great price on my part, and reasonable shipping charges, they shipped it right away.<br>I know I will be checking them for future parts.

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

Ordered a product and received within 2 days. Easy transaction and quick delivery.

I've had great service, quick shipment and awesome prices from Autoplicity. Definitely would recommend to anyone. I've placed multiple orders with them and everything is great!

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

great that it linked to amazon. I will be a repeat customer

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Best price I found and VERY fast shipping. Very happy.
