When it comes to pushing your ride to the limit, you need engine bearings that can keep up with your passion. That’s where these ACL Race Series Trimetal Engine Bearings come into play. They’re built for the serious driver who knows that performance isn’t just about speed; it’s about reliability under pressure. These bearings are designed for those high RPM moments, ensuring your engine stays happy even when you’re pushing it to the max.

• High Strength Overlay: The overlay plate is thinner but tougher, which means better fatigue resistance. You want your bearings to last, right?
• Hardened Steel Backs: These rod bearings feature hardened steel backs that hold the lining in place and keep everything snug in the housing. No one wants their bearings to shift during a hard run.
• Increased Crush: More crush means better retention. They’re not going anywhere once they’re in.
• No Flash Plating: Forget about that flash plating on the back. This design improves heat transfer and maximizes grip between the bearings and their housing. Better cooling means better performance.
• Increased Eccentricity: This feature helps counteract bore distortion at high RPM, making sure that hydrodynamic oil films form properly. It’s all about keeping that oil flowing.
• 3/4 Grooved Main Bearings: These are designed to optimize load distribution and oil flow to the conrod bearings. More oil where it counts.
• Tight Wall Tolerances: Consistency is key, and these bearings help maintain those crucial clearances.
• Enlarged ID Chamfers: Where needed, these chamfers accommodate the larger fillet radii found on performance crankshafts. It’s the little details that make a difference.
