Optimize Your Engine's Performance with Precise LS Main Bearing Clearance

Proper LS main bearing clearance is crucial for maximizing the performance, durability, and lifespan of your engine. By meticulously adhering to the optimal clearance specifications, you can unlock the true potential of your LS engine and enjoy a smooth, efficient, and responsive driving experience.

Table 1: Main Bearing Clearance Recommendations

Engine Type	Bearing Material	Clearances (in.)
LS1	Aluminum	0.0025-0.0035
LS2	Iron	0.0015-0.0025
LS3	Forged Steel	0.0020-0.0030

Effective Strategies for Setting LS Main Bearing Clearance

Use Precision Measuring Tools: Invest in high-quality micrometers or bore gauges to ensure accurate measurements. This will prevent overtightening or undertightening the bearings, leading to premature wear or catastrophic failure.

Follow OEM Specifications: Refer to the manufacturer's recommended LS main bearing clearance specifications for your specific engine model. Deviations from these values can compromise engine performance and reliability.

Engine Type	Main Bearing Bolt Torque (ft-lbs)
LS1	38-47
LS2	36-47
LS3	45-55

Lubricate Bearings Properly: Apply a thin, even layer of engine assembly lube to the bearing surfaces before installation. This lubrication ensures proper seating and reduces friction during initial operation.
