Supertech BMW N55 Forged 4340 H-Beam Conn Rod C-C Length 146.35mm - Set of 6

Forged from 4340 steel with an H-beam design, these connecting rods from Supertech are built to handle the demands of a high-performance BMW N55 engine. The center-to-center length is precisely 146.35mm, ensuring they fit correctly within the engine's architecture. This set includes six rods, ready to replace the factory components in your inline-six N55 powerplant.

The H-beam profile is a popular choice for performance builds because it offers a strong yet relatively lightweight design. This strength is crucial for handling the increased cylinder pressures and combustion forces found in tuned or modified N55 engines. Supertech uses 4340 steel, a material known for its excellent toughness and fatigue resistance, making these rods a solid choice for engines that see hard use or are being rebuilt for more power. The precision machining ensures that each rod meets strict tolerances for weight and dimensions, which is vital for engine balance and smooth operation.

When rebuilding or significantly upgrading your BMW N55 engine, using robust connecting rods like these is a key step. They are designed to be a direct replacement for the stock rods, simplifying the installation process for a mechanic. Ensure you have the correct rod bearings and fasteners, as these are typically sold separately and are critical for proper engine assembly. This set is a well-built foundation for an engine that needs to perform reliably under stress.
