If you're looking to crank up the performance of your engine, you might want to check out these ACL Race Series Engine Bearings. They’ve got a reputation for being tough enough to handle the demands of high RPM driving, and trust me, they deliver. Designed for a bunch of popular 4, 6, and 8-cylinder setups, these bearings are built for those who push their engines to the limit.
What Sets Them Apart:
- High-Strength Overlay: The overlay plate is thinner but stronger, which means better fatigue resistance. You want your bearings to last, right?
- Hardened Steel Backs: These aren't just any bearings. The hardened steel backs provide solid support for the lining and help keep everything in place.
- Improved Crush: You get increased crush for better retention. That means they stay put where they belong, even under stress.
- Heat Transfer: They’ve eliminated flash plating on the back, which really helps with heat transfer and keeps the grip tight between the bearings and housing.
- Increased Eccentricity: This feature is a game-changer. It compensates for bore distortion at high RPMs and helps form those hydrodynamic oil films you need for smooth operation.
- 3/4 Grooved Main Bearings: This design optimizes the load-carrying surface area and improves oil flow to the conrod bearings. More oil where it counts!
- Tight Wall Tolerances: Consistent wall tolerances mean you can keep your clearances in check, which is crucial for performance builds.
- Enlarged ID Chamfers: They accommodate larger fillet radii on performance crankshafts, so you won’t have to worry about fitment issues.
