When choosing the turbo kit for your bike, please consider the following information before you make your purchase.
First, Please choose the year range your bike fits into. This is important to ensure you get the correct parts for your bike.
Next, Please select if the kit will be a Stage 1 or Stage 2 version.
Stage 1 Kits are designed for bikes with stock displacements 88”- 117”. We do not recommend running them on larger displacement motors. Please choose the Stage 2 option.
Stage 2 Kits are designed for the larger displacement, 120” and above. These kits can also be installed on smaller displacements if you are planning on building the motor to a larger displacement later. For example, you can install a Stage 2 kit on a 114” motor if you plan on making it a 128” in the future.
