FASTRAX TUNE STOP TOOL

Now heres a tuning screwdriver with a twist. It has an adjustable length, which means you can pull out the screwdriver tip to the length that you desire to suite your nitro car or truck�s body width � perfect for reaching that hard-to-reach low-end needle-valve. The screwdriver tip can be collapsed to fit in tight toolbox trays, and your pocket!

But that is not it. The Tune Stop will also double up and act as a tool for stopping your engine by using the rubber end and pressing against the flywheel or exhaust outlet. No more shredded thumbs and fingertips here!
