King Engine Bearings Crankshaft Main Bearing Set Bimetal Aluminum Base Compatible with Toyota 5VZFE 1988-2002 4Runner Lexus ES250 ES300

This main bearing set is engineered to provide precise fitment and reliable rotational support for the crankshaft in compatible Toyota and Lexus engines. Manufactured with a bimetal construction featuring an aluminum base, the bearings offer an optimized balance of strength, durability, and wear resistance under various operating conditions.

Designed to maintain tight clearances and withstand high loads, these bearings effectively reduce friction and heat buildup, contributing to improved engine longevity and performance consistency. The aluminum base layer enhances fatigue resistance, while the overlay material ensures excellent conformability and embedability to accommodate minor debris and protect the crankshaft journal surface.

Key attributes include:

• Precision Engineering: Accurate dimensional tolerances for seamless crankshaft fitment and smooth rotation.
• Durable Materials: Bimetal construction combining aluminum base for strength and a specialized overlay for surface protection.
• Optimized Performance: Superior friction reduction and wear resistance support consistent engine operation under load.
• Corrosion Resistance: Material composition designed to withstand corrosive engine environments, enhancing service life.

These bearings are suitable for specific models spanning multiple years, ensuring compatibility with a range of Toyota 4Runner variants as well as Lexus ES250 and ES300 models. The high-quality manufacturing standards maintain the integrity of the rotating assembly, essential for maintaining engine reliability and efficiency.
