ACL Race Series Engine Bearings (1B1808H-.025) - Performance You Can Trust

If you're looking to push your Dodge Challenger (2008-2020) or Dodge Magnum (2005-2008) to the next level, the ACL Race Series Engine Bearings are a must-have upgrade. Designed specifically for high-performance applications, these trimetal engine bearings are engineered to handle the rigors of higher RPMs, ensuring your engine runs smoothly even under the most demanding conditions.

Why Choose ACL Race Series Bearings?

The unique combination of advanced design, high-grade metallurgy, and precise engineering makes these bearings stand out. They are crafted to deliver the reliability and performance that serious drivers expect:

• High-strength overlay plate with reduced thickness enhances fatigue properties, allowing for longer-lasting performance.
• Hardened steel backs on all rod bearings provide improved support for the bearing lining and enhance retention within the housing.
• Increased crush improves bearing retention, keeping everything securely in place during high-stress situations.
• Elimination of flash plating on the back of the bearings promotes better heat transfer, maximizing grip between the bearings and their housing.
• Increased eccentricity compensates for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films.
• 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the conrod bearings, ensuring your engine stays lubricated.
• Tight and consistent wall tolerances help maintain precise clearances, critical for performance builds.
• Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts, allowing for smoother operation.
