Complete Rod and Main Bearing Solution

Instead of purchasing bearings separately, this set includes both rod bearings and main bearings for complete lower-end engine assembly support.

Key benefits include:

• Simplified engine rebuild process
• Consistent bearing material across components
• Proper crankshaft support
• Improved oil clearance control
• Reliable durability under load

Replacing rod and main bearings during engine assembly is critical for maintaining proper oil pressure and crankshaft stability, especially in higher-mileage LS engines.

Critical for Oil Control and Engine Reliability

Rod and main bearings play a crucial role in:

• Supporting crankshaft rotation
• Maintaining stable oil pressure
• Reducing friction under load
• Preventing metal-to-metal contact
• Protecting internal engine components

Fresh bearings are especially important when rebuilding engines exposed to:

• High mileage
• Elevated RPM
• Increased horsepower
• Aggressive tuning
• Forced induction systems

Because nothing ruins a fresh LS build faster than realizing the old bearings looked “good enough” approximately 12 seconds before catastrophic failure.

Excellent Choice for LS Engine Rebuilds

The GM LS platform remains one of the most popular V8 engines ever produced thanks to its affordability, durability, and massive aftermarket support.

This King rod and main bearing set is ideal for:

• Budget LS rebuilds
• Performance street cars
• Truck engine refreshes
• LS swap projects
• Drift builds
• Turbocharged applications

Whether you’re building a reliable daily driver or a high-horsepower race engine, quality bearings provide the foundation for long-term durability and stable engine performance.
