If you're diving into the world of high-performance engines, you know that the right bearings can make all the difference. Let me tell you about the ACL Race Series Engine Bearings. These bad boys are crafted with a unique blend of design and metallurgy, specifically made to handle those high RPMs that our engines crave. Whether you’re working on a 4, 6, or 8-cylinder setup, these bearings have got you covered.

  • Lightweight but Tough: The high-strength overlay plate is thinner, which sounds counterintuitive, but it actually improves fatigue properties. You get the strength without the bulk.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs. This means better support for the bearing lining and it helps keep everything snug in the housing.
  • Improved Crush: We've cranked up the crush factor for better bearing retention. You want these bearings to stay put, trust me.
  • Heat Transfer: Forget about flash plating on the back. This design lets heat transfer more efficiently, which is key for keeping those bearings cool under pressure.
  • High RPM Ready: With increased eccentricity, these bearings can handle bore distortion when you're pushing the limits. They help form a hydrodynamic oil film that’s crucial for performance.
  • Optimized Oil Flow: The 3/4 grooved main bearings are designed to maximize the load-carrying surface area and ensure oil flows seamlessly to the conrod bearings.
  • Consistent Tolerances: You’ll appreciate the tight wall tolerances, which help maintain consistent clearances—no surprises when you’re revving high.
  • Chamfered Edges: Enlarged ID chamfers on the bearing edges are there to accommodate large fillet radii on performance crankshafts. This means a better fit for those high-performance builds.

Specifications:

  • Size: STD, .025, .25
  • Oil Clearance: Standard
  • Half Type: Upper & Lower
  • Material: Tri-metal
  • Min Std Shaft Size: 2.4784 in / 62.951 mm
  • Max Std Shaft Size: 2.4793 in / 62.974 mm
  • Min Std Tunnel Size: 2.6238 in / 66.645 mm
  • Max Std Tunnel Size: 2.6249 in / 66.672 mm
  • Max Wall at Crown: 0.072 in / 1.83 mm
  • Max Overall Length: 0.748 in / 19 mm

These bearings are a perfect fit for the Nissan 300ZX from 1984 to 1999, specifically the 4M2737A-STD ACL Nissan VG30DE V6 Standard Size Main Bearing Set from '90 to '97. If you’re looking to boost your ride's performance, these bearings are a solid choice. They’re built for the real deal, so you can hit those high RPMs with confidence.
