Toolbox Builder is the toolbox checklist in the AVB RaceLabs Pit Kit. Choose your Kart type: IAME X30, Rotax Max, Cadet GX200, KZ shifter, Vortex ROK, Rental / 4-stroke or Electric. The list then has three sections: Universal kit (16 items, from the 8–19 mm socket set and T-handle allen keys to the tyre pressure gauge, kart stand and fuel jug), the extras for your kart type, and Your extras.
The engine-specific section is the part people usually forget. X30 adds a plug socket with spare NGK plugs, a clutch puller, a charged starter battery, Tillotson diaphragms and a 219 chain breaker. Rotax adds the Dellorto jet kit and coolant. Cadet GX200 adds 4-stroke oil, recoil starter spares and feeler gauges. Electric adds charged battery packs, the charger and insulated tools. Forgetting the plug socket or the charger can finish your day before practice starts.
Tick items as you load the van. A counter shows how many are ticked, and the GO / NO-GO pill turns GO only when every critical item is ticked. Critical items are marked with an exclamation icon. Save the run (Save — all items ticked, Save — critical items ticked, or Save anyway) and it is added to Saved runs with the kart type, ticked count, date and a GO or NO-GO icon, as a record that the box was packed. Switching kart type clears the ticks. The in-app note reminds you that these are starter lists and your engine builder's spec sheet takes priority.
Everything works offline on the phone. Saving runs is unlimited. On Free you can add your own extra items for 1 kart type. Premium lifts that limit and adds PitSync cloud backup.
