We have a range of short block assemblies ready to ship as you order.  Each assembly starts with brand new block halves direct from Subaru, which are thoroughly cleaned, inspected and measured, before being honed to perfectly suit the appropriate pistons.  All components are individually selected and checked to ensure they are perfectly matched, the blocks are then assembled here at RCM by our own expert technicians.  Finally, each assembly is given an RCM identification badge prior to dispatch.
