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 9 MIVEC engine. All of the camshafts in this range are ground on Kelford Cam's Toyoda CNC masterless cam grinder to consistently deliver the highest quality product.
Kelford Cam's '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.
They 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.
However, if you can't find your perfect camshaft within their range, designing custom profiles is their specialty! Simply order the custom camshaft and provide us all the details of your build. Confidential development for race teams is also available.
