Please note that these camshafts are ground to order and will take approximately 5 working days, please ensure you have ordered the correct components as they are non-returnable.

All SBD camshafts have been designed in conjunction with Kent Cams and extensively tested on the dynamometer.

*Power gains can only be achieved provided your engine has the components to complement it. E.g. exhaust manifold & system, induction system & cylinder head porting where required. If you look at our upgrade kits they will give you more help.

Please see instruction sheets for information regarding the camshafts, their installation & running in.
