This range of Kelford Camshafts suit the Version 5-6 engines that do not have AVCS. In this range we list camshafts to suit the stock bucket with shim on top and also some higher lift versions that suit engine builders that change to the 'shimless' buckets. The cams for shimless buckets can not be used on the conventional shim on top system. We believe that Kelford Cams make the best high performance Subaru camshafts available. All of these cams are manufactured in-house using ultra modern design systems and ground using masterless CNC grinders with CBN cutting wheel technology for superior quality and consistency.
