The crate that comes with your SRT Demon will provide all the tools required to move from the street to the drag strip.
A hydraulic floor jack will get the car off the ground for easier tire swaps.
Hydraulic floor jacks are far superior to the ones that come with most cars, but they're annoying to lug around in the trunk (ask me how I know).
You'll also get an electric impact driver with a charger for the battery. This'll get your wheels on and off quickly.
To make sure that every bolt is tightened to spec, there's also a torque wrench.
A tire pressure gauge is handy for deflating your tires to the proper drag strip pressure. As for reinflating, well, um...
The fender cover will keep your sheet metal from getting all scratched up as you work under the hood.
And, of course, there's a bag in which to keep all the aforementioned tools.
