King Engine Bearings MB5835SI0.75 Main Bearing Set 0.75mm Undersize Chevy 2.0L 2.2L LN2

The King Engine Bearings MB5835SI0.75 is a precision-engineered main bearing set designed for Chevrolet 121ci (2.0L) and LN2 134ci (2.2L) engines. This bearing set features a 0.75mm undersize specification with a .002" oversize outer diameter, making it the modified version of the standard MB5088SI bearing set for machined crankshafts.

Key Features:

• SI-Series bi-metal construction with aluminum-silicon base material
• Aluminum alloy strengthened with 2.5-3% silicon for enhanced durability
• 0.75mm undersize bearing dimension for reground crankshafts
• .002" oversize outer diameter allows repair of housing bore by line honing
• MaxFlange (FL ON MAX) flange oversize specification
• Lead-free material for environmentally responsible engine rebuilding
• King Bull's Eye Tolerance™ technology maintains wall thickness within +/- .0001"

King SI-Series main bearings are engineered specifically for OE replacement applications and aftermarket engine rebuilding projects. The bi-metal aluminum-silicon construction provides excellent strength and durability for medium-load engines, making it particularly well-suited for engines with nodular cast iron crankshafts. The oversized outer diameter design enables professional engine builders to salvage blocks with worn bearing bores through precision line honing, extending the service life of the engine block.

As a lead-free bearing solution, this set meets modern environmental standards while delivering the performance and reliability King Engine Bearings has been known for since 1960. Each bearing is manufactured to exacting tolerances using advanced machining, overplating, and computerized wall thickness monitoring for consistent quality and optimal fit.
