ACL Engine Bearings 5M8392A-.25 Oversized Main Bearing Set for Toyota 4 999-1332cc 1985-1999 - 5M8392A-.25

If you're diving into the world of performance engines, you know that the little things can make a huge difference. That’s where these ACL Race Series Engine Bearings come into play. They're not just another part; they’re built for the real demands of high RPM situations. Whether you’re pushing your Toyota Corolla to the limits or just want a reliable upgrade, these bearings have you covered.

What makes them stand out?

  • First off, the overlay plate is high strength but thinner. This means better fatigue properties, which is crucial when you're revving high.
  • All rod bearings come with hardened steel backs. This gives you solid support for the bearing lining and helps keep everything snug in the housing.
  • They’ve cranked up the crush on these bearings for better retention. You want them to stay put, especially when the engine's working hard.
  • No flash plating on the back—this is a big deal for heat transfer. It helps the bearings dissipate heat better and grip the housing tighter.
  • Increased eccentricity? Yes, please! This helps with bore distortion at high RPMs and aids in creating those hydrodynamic oil films that keep everything lubricated.
  • The main bearings are 3/4 grooved, optimizing the load-carrying surface area and ensuring oil flows smoothly to the conrod bearings.
  • With tight, consistent wall tolerances, you’ll maintain clearances that are spot on. No more guessing games.
  • And check this out—enlarged ID chamfers on the edges where needed to fit those performance crankshafts. It’s all about the details.

Specifications:

  • Size: STD 0.25
  • These ACL Duraglide Main Bearings are perfect for OEM engines and are a solid choice for anyone looking to replace worn-out parts.
  • Made from tri-metal, these bearings have been put to the test in countless engine rebuilds.

Fitment:

These bearings are a perfect match for your Toyota Corolla from 1983 to 2019, specifically the 5M8392A-.25 model. They also fit the 999-1332cc engines, including the 1E, 2E, and 4EFE with a 0.50 oversized main bearing set from 1985 to 1999.

So, if you're looking to boost your engine's reliability and performance, these bearings are a solid investment. They’re designed for those who understand what it takes to keep an engine running strong.
