ACL rod bearings combine advanced materials and manufacturing techniques to meet the rigorous demands of high-performance and heavy-duty applications. Key features include:

• Precision-engineered to .25mm (0.010") undersize for exact fitment
• Compatible with multiple HEMI V8 engines: 5.7L, 6.1L ESF, 6.4L ESG/ESH, 6.2L supercharged variants
• High-quality tri-metal construction for enhanced wear resistance and durability
• Optimized for high-load and high-RPM conditions common in performance and heavy-duty use
• Manufactured to strict OEM tolerances for reliable engine operation
• Designed to reduce friction and improve oil film strength under extreme conditions
• Ideal for both street performance and motorsport applications
• Compatible with a wide range of Chrysler, Dodge, Jeep, and Ram models from 2003 through 2025

Construction & Design:

ACL rod bearings are constructed using a tri-metal layering process that combines a steel backing with a durable overlay of copper-lead alloy and a thin layer of soft metal to provide excellent conformability and embedability. This design ensures the bearings can accommodate minor debris and surface imperfections while maintaining a strong oil film to prevent metal-to-metal contact.

The bearings are engineered to withstand the high combustion pressures and temperatures generated by modern HEMI V8 engines, including supercharged variants. Their robust construction helps reduce wear and extend engine life, even under aggressive driving or towing conditions.

Installation & Fitment:

Installation of the ACL High Performance Rod Bearing Set requires standard engine rebuild procedures and should be performed by a qualified technician. The .25mm undersize specification means these bearings are intended for use in engines where the connecting rod journals have been machined to this dimension. Proper measurement and clearance checking are essential to ensure optimal performance and longevity.

This bearing set fits a broad range of vehicles including Dodge Ram 1500 (2003–2025), Dodge Magnum (2005–2008), Dodge Charger (2006–2025), Dodge Challenger (2008–2025), Chrysler 300 (2012–2025), Jeep Grand Cherokee (2012–2021), Dodge Durango (2018–2025), Jeep Wrangler (2021–2025), and Jeep Grand Wagoneer (2022–2025) equipped with the specified HEMI engines.

What's Included:

• Set of 8 connecting rod bearings sized at .25mm (0.010") undersize

Ideal For:
