Malossi MHR Racing Crankshaft with HPC Full Circle Design

MALOSSI MHR Racing Shaft solid cheek shaft in Race design.

Very high quality processed and executed racing shaft, where the cheeks are made of solid metal. This provides due to the full weight of the shaft for a smooth engine running.

The HPC (= High-Primary-Compression) version also increases the pre-compression, which leads to a better filling of the cylinder over the entire speed range.

The bearing is for a racing shaft with silver cages!
