Product Details

The ACL Bearings 4B603H-20 Race Series connecting rod bearing set is engineered for high-performance and racing applications in Ford Kent, Lotus Twin Cam, and Pinto engines. This .020" oversize bearing set delivers the durability and precision required for high-RPM race engines.

Key Features:

  • Trimetal construction with high-strength overlay plate featuring reduced thickness for improved fatigue resistance
  • Hardened steel backing on all rod bearings improves lining support and retention in the housing
  • No flash plating on bearing backs for enhanced heat transfer and maximum grip between bearing and housing
  • Increased eccentricity compensates for bore distortion at high RPM and assists hydrodynamic oil film formation
  • Enlarged ID chamfers on bearing edges accommodate performance crankshafts with large fillet radius
  • Tight, consistent wall tolerances help maintain precise clearances
  • .020" oversize for rebuilt or re-machined crankshafts

ACL Race Series bearings feature advanced metallurgy with lead, tin, copper, and nickel for superior strength and seizure resistance. Compatible with Ford Kent (1098cc-1598cc), Lotus Twin Cam, and Pinto engines including applications in Ford Escort, Cortina, Capri, Fiesta, and classic Lotus vehicles.

beat price on the part i was looking for

Fantastic price, positive communication, arrived before promised worked out great!

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Pleasure to deal with, will use for future purchases as well.

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!
