Product Details

ACL Performance Race Bearings are manufactured with a tri-layer metal with a hardened steel backing in order to withstand high RPM conditions, high stress loads, and high temperatures. This Race Series connecting rod bearing set features a 23.5mm wide bearing design specifically engineered for high-performance and racing applications.

Key Features:

  • High strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
  • Increased crush for improved bearing retention
  • Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing
  • Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films
  • Enlarged chamfers to accommodate large fillet radius on performance crankshafts
  • Tight consistent wall tolerances for maintaining precise clearances
  • Made in Australia

RACE Series rod and main bearings are standard components in Race engines that have set records and won championships from Mexico to Bonneville - from sport compact drift racing to small block NASCAR, IHRA and NHRA competitions. The STD designation indicates this is a standard size bearing set with identical bearing halves, ideal for both street performance and all-out racing applications.

I was able to find my product at the lowest price here.

Rated good. Always hate delay of having to order, but delivery time was reasonable.

quick and easy found exactly what i was looking for

Very fast transaction and shipping info.. Best price found on the internet..

Excellent place to deal with. I am a returning customer and love the fast shipping!!

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Prices are very good. There was a slight issue with my order, but it was taken care of after being passed around to a few different departments when I called. Would order from 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 price, fast shipping, excellent customer service. I will definitely do business with them in the future.
