Key Features
ACL Race Series bearings utilize advanced materials and manufacturing processes to provide outstanding performance and longevity. Key features include:
- Precision-engineered to .025mm (0.001") undersize for exact crankshaft journal fitment
- Constructed from high-grade tri-metal materials for enhanced wear resistance and durability
- Optimized for high load capacity and excellent thermal stability in demanding environments
- Designed to reduce friction and improve oil film retention, extending engine life
- Manufactured to meet or exceed OEM specifications for reliable, consistent performance
- Corrosion-resistant coating protects against engine contaminants and installation damage
- Ideal for both street and track applications requiring high durability and precision
Construction & Design
Each ACL Race Series main bearing features a tri-metal construction combining a robust steel backing with a copper-lead alloy layer and a thin babbitt overlay. This multi-layer design provides a durable bearing surface capable of withstanding the high loads and elevated temperatures typical of performance HEMI engines. The precise .025mm undersize dimension ensures a tight, secure fit on the crankshaft journals, minimizing clearance and maximizing oil film strength for superior lubrication.
Rigorous quality control and finishing processes guarantee smooth bearing surfaces and consistent thickness, critical for maintaining proper oil clearance and preventing premature wear. The corrosion-resistant coating further enhances durability by protecting the bearing surface from contaminants and handling damage during installation.
Installation & Fitment
The ACL Race Series Main Bearing Set is a direct replacement for Chrysler 5.7L and 6.1L HEMI V8 engines from 2003 to 2025. Installation requires standard engine rebuild procedures, including precise measurement of crankshaft journal diameters and bearing clearances to ensure optimal fitment. The .025mm undersize specification accommodates crankshaft grinding or wear, making these bearings suitable for both rebuilds and performance upgrades.
Proper lubrication during assembly and adherence to torque specifications are essential to maximize bearing life and maintain engine reliability. This bearing set fits the following vehicles:
- 2003–2025 Dodge Ram 1500 5.7L HEMI

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
