Description

IMPORTANT NOTICE: Note for Pistons, Rings, Rotors, Rods and engine internalsUnless otherwise specified, some brands supply brake rotors, pistons, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.(keyword: rod)Important Note Regarding Oils, Additives, Aerosols & LiquidsThis listing may contain a product with transport restrictions. Items containing oils, additives, aerosols, adhesive or other liquid/chemical-based products may be subject to shipping restrictions depending on their current warehouse location, carrier requirements, and applicable transport regulations. Some liquid and aerosol products are restricted for air freight or certain road freight routes and may require alternative transport methods or dispatch from a specific warehouse. While the majority of these items ship without issue, these factors can occasionally affect available shipping options or delivery timeframes. If you are working to a tight deadline, require urgent delivery, or are unsure whether a product can be shipped to your location, we recommend contacting the StreetFX team prior to placing your order so we can confirm availability and the most suitable freight option.(keyword: oil)Images are supplied by the manufacturer and may be generic.

Product Overview

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.
• *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.
