The ACL Race Series 6B2433H-.025 connecting rod bushes are designed for Porsche GT3 4.0 and 4.2 engines. This 0.025 mm version allows for precise adjustment during mounting when crankshaft measurements and the desired oil clearance require this size.
Developed for heavily loaded engines, the ACL Race Series range is particularly well-suited for engine tuning, racing, and rebuilds requiring precise control of operating clearances.
Part number 6B2433H-.025 differs from the STD version in its specific 0.025 mm dimension. This small dimensional variation allows the engine builder to select the bearings based on measurements taken during crankshaft inspection and the oil clearance required for mounting.
The selection of this dimension must therefore be made after precise measurement of the crankpins. The choice between an STD, 0.025 mm, or 0.25 mm bearing depends on the measured sizes and the desired clearance, and not directly on the engine power.
Connecting rod bushes serve as the interface between the connecting rods and the crankshaft journals. The oil film between these components limits direct contact between the moving surfaces, making clearance control particularly important when assembling a high-performance engine.
The ACL Race Series 6B2433H-.025 bushings are therefore a solution for tuning or rebuilding a Porsche GT3 engine when dimensional specifications precisely require the use of the 0.025 mm dimension.
