      Performance 264/268 Degree, 11.00/10.50mm lift Cams for EVO 8 4G63.

      The Kelford Cams range of camshafts for Mitsubishi 4G63 DOHC engines are renowned worldwide for their superior results. This range is for the DOHC 4G63T Evolution 8 engine. All of the camshafts in this range are ground on our Toyoda CNC masterless cam grinder to consistently deliver the highest quality product.

      Our 'TX' range of camshafts for Mitsubishi 4G63 DOHC engines have the best available lobe designs, featuring low seat timing and maximum valve area while retaining perfect valve control at high RPM. Every cam in the range features the same lobe design as our mega popular 272 degree camshaft.

      We have developed a proven range of camshafts for this engine to suit most applications, including a low lift 272 degree cam to suit stock valve springs and high lift designs for the more serious applications.

      However, if you can't find your perfect camshaft within our range, 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.
