ACL Race Series Connecting Rod Bushes 6B2433H-STD Porsche 911 GT3 4.0 4.2

The ACL Race Series 6B2433H-STD connecting rod bushes are designed for Porsche GT3 4.0 and 4.2 engines. This STD version is intended for mounting on a crankshaft that retains its standard sizes, following metrological inspection of the crankshaft journals and oil clearance.

The ACL Race Series range is designed to meet the demands of high-performance and racing engines. These bearings provide the interface between the connecting rods and the crankshaft journals, where precise control of operating clearance is essential for maintaining the oil film.

STD version for crankshafts with standard sizes

Part number 6B2433H-STD corresponds to the standard version of this family of ACL bearings. It is intended for engines whose crankpins remain within the sizes specified for a STD mounting and do not require a specific size.

This version thus differs from part numbers 6B2433H-.025 and 6B2433H-.25. The choice between these different dimensions must always be based on the actual measurements of the crankshaft and the desired oil clearance during assembly.

ACL Race Series Connecting Rod Bearings for Porsche GT3 Engines

In a heavily loaded Porsche GT3 engine, checking the clearances at the connecting rods directly affects the quality of the engine assembly. The ACL Race Series 6B2433H-STD main bearings are suitable for engine tuning or rebuilding when metrological measurements confirm that the standard size should be used.

Before mounting, it is essential to measure the crankshaft journals and check the oil clearance. The selection of a bearing size should not be determined solely based on the engine’s power output or tuning level.
