Construction & Design:

ACL rod bearings are crafted from high-quality bearing alloys that combine strength with excellent fatigue resistance. The materials are selected to provide a durable surface that can endure the demanding conditions of high-performance engines, including elevated temperatures and pressures. The bearing shells are engineered with precise tolerances to ensure optimal oil film thickness, which is critical for reducing metal-to-metal contact and preventing premature engine wear.

The undersize specification of 0.025mm accommodates engine rebuilds or repairs where crankshaft journals have been machined, ensuring a perfect match and maintaining proper bearing clearance. This precision engineering supports consistent performance and helps extend the life of your engine components.

Installation & Fitment:

Installation of the ACL High Performance Rod Bearing Set is straightforward for professional mechanics and experienced enthusiasts. These bearings are designed as direct replacements for the specified Hemi engines and vehicle models, requiring no modifications to the connecting rods or crankshaft beyond standard machining practices. Proper measurement of journal sizes and bearing clearances is essential to ensure correct fitment and optimal engine performance.

Always follow manufacturer torque specifications and assembly procedures during installation to guarantee reliable operation and avoid premature bearing failure.
