A camshaft phaser arrangement configured for a concentric camshaft assembly having an inner camshaft and an outer camshaft is provided. The camshaft phaser arrangement can facilitate independent phasing of intake and exhaust valves. The camshaft phaser arrangement includes a first driven wheel and a second driven wheel, both configured to be driven by a driving wheel. A first camshaft phaser is connected to the first driven wheel and configured to be connected to either the inner or outer camshaft. A second camshaft phaser is connected to the second driven wheel and configured to be connected to either the inner or outer camshaft which is not connected to the first driven wheel. A motion transfer assembly can connect the second camshaft phaser to the concentric camshaft assembly. One or both of the camshaft phasers can be an electric camshaft phaser or a hydraulic camshaft phaser.
