Construction & Design:

ACL Race Rod Bearings are crafted from high-quality bearing alloys that provide excellent fatigue strength and resistance to wear. The materials and manufacturing processes are refined through decades of engineering expertise, ensuring consistent performance under extreme conditions. The bearings are precision machined to tight tolerances, allowing for optimal fitment and oil clearance tailored to your engine’s needs.

The availability of different sizes—including standard, extra oil clearance, and oversize options—allows for flexibility during engine rebuilds or modifications, ensuring proper bearing clearance and reliable operation.

Installation & Fitment:

These rod bearings are designed as direct replacements for the factory components in the 2AZ-FE engine of the specified Scion models. Installation requires standard engine disassembly and bearing replacement procedures. It is important to measure and verify bearing clearances during installation to ensure proper fit and performance. Thrust washers are not included and should be purchased separately to complete the assembly.
