Unlock the Power of LS Main Bearings for Unparalleled Engine Performance

In a world where performance reigns supreme, LS main bearings play a pivotal role in ensuring your engine operates at peak efficiency. Crafted from the finest materials and engineered with precision, these essential components bear the brunt of relentless forces, allowing your engine to reach its full potential.

Benefits of LS Main Bearings

Exceptional Durability:

Made from high-strength materials like forged steel or ductile iron, LS main bearings boast exceptional durability, withstanding extreme loads and minimizing wear over time.

Material	Strength	Wear Resistance
Forged Steel	High	Excellent
Ductile Iron	Medium	Good

Reduced Friction:

Featuring low-friction coatings like Teflon or molybdenum disulfide, LS main bearings minimize friction between the crankshaft and block, reducing parasitic losses and improving engine efficiency.

Coating	Friction Reduction
Teflon	10-15%
Molybdenum Disulfide	5-10%

Improved Oil Flow:

Precision-engineered oil grooves and channels ensure optimal oil flow to the crankshaft, maximizing lubrication and heat dissipation.

Oil Grooves	Oil Flow Rate
Single	15-20%
Double	25-35%

How to Choose the Right LS Main Bearings

Selecting the right LS main bearings is paramount to maximizing engine performance. Consider the following factors:

Engine Type:

Different engine designs require specific bearing sizes and materials. Refer to your engine documentation for the recommended specifications.

Performance Goals:

High-performance engines demand bearings with enhanced durability and reduced friction. Choose bearings rated for higher loads and coated for lower friction.

Budget:

LS main bearings vary in price from budget-friendly options to premium performance offerings. Determine your budget and select bearings that provide the best value for your needs.

Industry Insights & Maximizing Efficiency

According to the Society of Automotive Engineers (SAE), proper LS main bearing selection and installation can improve engine efficiency by up to 5%. Follow these tips:

Use Precision Tools:

Invest in precision measuring tools like micrometers and dial calipers to ensure accurate bearing installation.

Lubricate Adequately:

Apply a liberal amount of engine assembly lube to the bearings before installation to prevent dry starts.

Tighten Gradually:

Gradually tighten the bearing bolts in a specified sequence and torque them to the manufacturer's specifications to ensure proper seating.

Getting Started with LS Main Bearings

Installing LS main bearings is a straightforward process that can be completed with basic mechanical skills. Follow these steps:

Remove the oil pan and crankshaft.

Clean the bearing surfaces of the block and crankshaft.

Lubricate the bearings and install them in the block.

Install the crankshaft and oil pan.

Tighten the bearing bolts to the specified torque.

Common Mistakes to Avoid

Over-Torquing Bolts:

Over-torquing bearing bolts can damage the bearings or block. Use a torque wrench and follow manufacturer's guidelines.

Incorrect Bearing Installation:

Incorrectly installed bearings can lead to premature failure. Ensure the bearings are seated properly and oriented correctly.

Using Incompatible Lubricants:

Some lubricants are not compatible with LS main bearings. Always use a recommended engine assembly lube.
