Original quality upper and lower main bearing 038105561AM for A3 S3

Original Quality Upper & Lower Main Bearing Set 038105561AM for Audi A3 & S3, OEM Standard Crankshaft Main Shells, High Wear Resistance & Anti-ablation, Reliable Wholesale Engine Overhaul Parts

Core Advantages

This matched upper and lower crankshaft main bearing set with OE number 038105561AM is manufactured strictly per original factory standards for Audi A3 and performance S3 models with supporting engine codes. All dimensional specifications including inner bore diameter, wall thickness, oil storage grooves and positioning tabs fully comply with OEM drawings, enabling seamless assembly during engine overhaul without trimming or grinding.

The main bearing features a three-layer composite metal structure with thick high-tensile steel back as the base layer to deliver strong structural stability against high engine load. The middle anti-fatigue alloy layer effectively resists long-period alternating impact loads from crankshaft rotation, while the surface soft anti-friction alloy coating maintains a uniform lubricating oil film at all operating speeds. This triple-layer construction prevents metal-to-metal dry friction and avoids bearing melting, ablation and seizure under intense driving conditions such as rapid acceleration and high-speed cruising.

Precision-machined oil distribution grooves on each bearing surface retain adequate engine oil between the bearing and crankshaft journal, stabilizing oil pressure, cutting mechanical friction noise and lowering overall fuel consumption. Built-in positioning lugs lock the bearings firmly inside the engine main bearing caps to eliminate rotation, shifting and eccentric wear during high RPM operation. Smooth chamfered edges protect the crankshaft journal surface from scratches during installation.

Every finished main bearing set undergoes rigorous factory inspections, including high-temperature ablation testing, cyclic fatigue testing and dimensional tolerance calibration. It completely resolves common engine faults triggered by worn original main bearings: abnormal deep knocking noise during acceleration, unstable oil pressure, power drop and excessive oil consumption. With OEM-matching accuracy and complete upper-lower bearing matching, this main bearing kit is a top-choice bulk procurement spare part for global Audi repair shops and VAG engine parts distributors specializing in A3 and S3 overhaul maintenance.
