Now hereâ€™s 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 truckâ€™s body width â€“ 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! If that isnâ€™t cool enough, it also has a CNC machined handle with a knurled grip and the JLR Racing logo printed on the side.
Now hereâ€™s the kicker; it has a rubber end cap thatâ€™s actually designed as an engine stopper. Just place the rubber end cap against you nitro vehicleâ€™s exhaust tip and the engine stops immediately. Pretty trick!
