Product Details

The ACL Bearings 4B1955-.25 is a high-performance connecting rod bearing set engineered with trimetal construction for enhanced durability and reliability in demanding applications. This 0.25mm undersize bearing set is designed for Honda D15 engines (1488-1493cc) and features ACL's proven Race Series technology.

Key Features:

  • Trimetal construction combines optimal strength, fatigue resistance, and embeddability
  • 0.25mm undersize dimension accommodates crankshafts that have been machined during rebuilds
  • High-strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backing improves bearing support and retention in the housing
  • Elimination of flash plating on bearing backs improves heat transfer and maximizes grip
  • Tight, consistent wall tolerances help maintain precise clearances during assembly
  • Complete set includes all bearing halves required for connecting rod installation

Designed to withstand higher RPM conditions in turbocharged, supercharged, and naturally aspirated performance builds, these bearings deliver the strength and precision needed for both street performance and racing applications. The unique combination of design, metallurgy, and engineering makes ACL bearings the choice of professional engine builders worldwide.

On Monday I placed an order for a Moroso Battery Switch (which was competitively priced BTW) and sitting here Wed afternoon I've got my switch in hand. Autoplicity was perfect every step of the way, including immediate notification of the order receipt, notification of shipment, even notification that it had been delivered (and it was waiting on my front porch). Packing was suitable too. Couldn't be happier. Buy with confidence. Kev

Quick turnaround and the best prices on the web!

thanks hope it fits

I ordered a Derale 14204 Trans oil pan from Autoplicity -<br>it arrived quickly, in good shape (was well packed for shipment)<br>More than pleased.... (best price was a bonus)<br>-HBP-

Autoplicity had the lowest listing price for a part which I had done extensive research. To make the deal much sweeter, free shipping! On top of that, part was delivered in only a few days! Really, there was no reason NOT to order from them. Great prices and fast response are the reasons why I look forward to continued business with Autoplicity. Overall a positive experience, so I highly recommend.

Very good price on k&n air filter, will definitely order from autoplicity again.

I did a price comparison for hard-to-find Redline motor and tranmission oil of over 30 different vendors and websites through Amazon, E-bay, Google, etc. and Autoplicity had the best price by 25-30%. It was a no-brainer to order from them, and their website is easy search and manage. And their shipping charges aren't too bad either.
