This article explains how to add a Sim Racing Studio 2 Channel Extension or a ButtKicker Gamer 2 to your existing ShakeKit.

Adding a Sim Racing Studio 2 Channel Extension or a ButtKicker Gamer 2 to a Sim Racing Studio ShakeKit increases the number of channels from 4 up to 5 or 6. This allows the ShakeKit to focus on the subtle suspension, road and g-force effects while the SRS 2 Channel Extension or a ButtKicker Game 2 handles the engine and other effects.


Use the steps below to add a SRS 2 Channel Extension or ButtKicker Gamer 2 to a ShakeKit. The video below will show the installation process:
