ACL Aluminum Main Bearing Set 5M8392A-STD for Toyota 1E/2E/4EFE 85-99 - 5M8392A-STD

Alright, gearheads, let's talk about the ACL Race Series Engine Bearings. If you’re pushing your engine to the limits, you need bearings that can keep up. These aren’t just any bearings; they’re designed for serious performance. Whether you’ve got a 4, 6, or 8-cylinder setup, these bad boys are built to handle higher RPMs without breaking a sweat.

What Makes Them Stand Out:

  • High Strength Overlay: The overlay plate is thinner but tougher, which means better fatigue resistance. Perfect for those high-rev situations.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs. This helps support the lining and keeps everything snug in its housing.
  • Increased Crush: This feature boosts bearing retention, so you won’t have to worry about them shifting around when the engine gets hot.
  • No Flash Plating: Forget about that extra layer that can mess with heat transfer. These bearings are designed to maximize grip and efficiently transfer heat.
  • Increased Eccentricity: This compensates for bore distortion at high RPMs, helping to create those all-important hydrodynamic oil films.
  • 3/4 Grooved Main Bearings: This design optimizes the load-carrying surface area and ensures oil flows smoothly to the conrod bearings.
  • Tight Wall Tolerances: Consistency is key. These bearings maintain tight tolerances, so you get reliable clearances every time.
  • Enlarged ID Chamfers: Where needed, these chamfers accommodate large fillet radii on performance crankshafts. No more worrying about fit issues!

Specifications:

  • Sizes: STD, .025, .25, 0.5
  • Oil Clearance: Standard
  • Half Type: Identical Halves
  • Material: Tri-metal with hardened steel backs
  • Min Std Shaft Size: 2.3616in / 59.984 mm

  • Min Std Tunnel Size: 2.5197in / 64.000 mm
  • Max Std Tunnel Size: 2.5205in / 64.020 mm
  • Max Wall at Crown: 0.0789in / 2.005 mm
  • Max Overall Length: 0.7480in / 19.00 mm

Fitment:

These bearings are a solid match for:

  • Subaru Forester (1998-2017)
  • Subaru Legacy (1990-2017)

So, if you’re looking to keep your engine running smoothly at high RPMs, these ACL Race Series Engine Bearings are a no-brainer. They’re built for performance and ready to take on whatever you throw at them.
