These Steeda Supercharger Pulleys are made from Steel not aluminum and have holes drilled around the center of the pulley to lower the rotational weight. This is the highest quality pulley available for the Cobra.

3.10" pulley 1-2psi over stock, requires performance tune.
Testing has shown 25+ horsepower.

2.81" pulley 4-5psi over stock, requires performance tune & shorter belt.
Testing has shown gains of 60+ horsepower.

Pulley Removal Tool
To make the job easier we have a tool designed specifically for the removal of a Cobra blower pulley.

Serpentine Belt for 2.81"
When running a 2.81" pulley you will need a shorter serpentine belt to keep tight on your blower for maximum boost.
