ACL Bearings 5M1538H-STD Race Series Main Bearings

Main Bearings
Race Series
Tri-Metal
Upper & Lower

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings.

Designed to withstand higher RPM conditions, ACL Race Series Connecting Rod Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature:

  • 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.
  • 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
  • Tight consistent wall tolerances to help you maintain consistent clearances.
  • Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.

Out of all the websites I've used to find my item, this was the lowest cost, and I'm so happy that I found them! Keep up the great work guys!

great site

good prices

So far found what I've been looking for so I'm satisfied currently

Don't know if it accepted the coupon code but shopping was easy.

Recommended by a fellow RegalGS member. Cheaper than Amazon. I haven't had the opportunity to put them on yet, but everything looks good.

I HONESTLY thought it was too good to be true! Almost 100$$$ less than any other place, I took a chance and ordered my ready lift leveling kit and it was here within 3 days! I received an email instantly with a tracking number, and was followe up with an email once it was delivered. EXTREMELY HAPPY! Thank you Autoplicity!

Easy to order and a great price - look forward to receiving my parts!

better price than anyone on eBay, and in stock and shipped immediately, paid one day had it the third day

Very quick and painless. I love that you accept Amazon payments.

Excellent so far!

I did a pretty extensive search looking for a good price on a specific set of Autogage gauges. They had the best price and were in stock with quick notification of shipment. Order # 27510 should be here soon so I can finish my project. Would so business with again.
