Designed for Stock and Performance Applications

Rod bearings play a critical role in maintaining proper lubrication and crankshaft support under load. The SI Series bearings are engineered to support both factory-style rebuilds and moderate-to-high performance engine combinations.

These bearings are ideal for:

• Stock LS engine rebuilds
• Camshaft upgrade builds
• Turbocharged LS setups
• Supercharged applications
• Street and strip performance engines
• Daily-driven LS swaps

Because rod knock is one of those sounds every LS owner recognizes instantly… right before pretending they didn’t hear it.

Whether you are running a naturally aspirated LS build, turbocharged setup, or high-RPM race engine, these Michigan Motorsports rod bearings give you the strength and performance needed to deal with extreme conditions.

Reliable Oil Control and Bearing Protection

Proper bearing performance is essential for maintaining:

• Stable oil pressure
• Crankshaft journal protection
• Reduced friction under load
• Consistent lubrication at higher RPM
• Long-term engine durability

Fresh rod bearings become especially important in engines exposed to:

• Elevated cylinder pressure
• Higher RPM operation
• Increased horsepower
• Aggressive tuning
• Heavy towing or racing conditions

Replacing worn bearings during a rebuild is inexpensive insurance compared to replacing a damaged crankshaft or complete short block.

Built to resist high quite a bit, elevated temperatures, and aggressive driving, this rod bearing set is a should-have upgrade for any LS engine rebuild or performance build. Michigan Motorsports – Precision Engineered for LS Performance.
