Kelford Cams - 4AGE 20V Camshafts

The Kelford range for Toyota 4A-GE engines features purpose built profiles that maximise lobe area on these small bucket engines. Some cams work with the VVT and others can either utilise the VVT or you can use adjustable gears if you wish to set fixed timing. These cams suit both the generation 4 silver top engines produced from 1991to 1998, and the generation 5 black top engines produced from 1995 to 1998.
