Kelford Cams RB25 VCT Camshafts

The Kelford Cams range of camshafts for Nissan RB25 NVCS/VCT engines. The RB25 NVCS engine is bought out in Nissan's R33 Skyline AKA the "BOAT". This catalogue range is designed for hydraulic lifter engines, however solid profiles are available on request. The low lift lobe designs on the A and A2 cams have proved very popular because there is no requirement for head clearancing.

RB camshafts are also fitted with two different kinds of triggers; by default we fit the spline and half moon type, if you need the "yoke shaped" type please let us know when ordering.

If you can't find your perfect camshaft within our catalogue, designing custom profiles is our specialty! Simply order the custom camshaft and provide us all the details of your build. Confidential development for race teams is also available.
