Black tire break-in drill adaptor kit

Manufacturer: JConcepts

Part No: JC2871-2


One of the most used tools on the 1/10th off-road racing scene is a tire break-in device. It’s a pretty simple combination of a standard hex drive shaft for a typical drill but extended and given some lock driven flats, the simple item turns into a very useful tool around the track. An aluminum 12 and 17mm hex adaptor slides over the shaft to give racers the option of which type of vehicle (1/10th or 1/8th) they are preparing tires for.


The flywheel nut features a large diameter for grip and adjustment and the ability to flip directions for deeper dish shaped wheels. It also has stealth black anodizing, laser etched logo, grippy knurling and a lightened design for quick function and easy storage. As always, each set is backed with JConcepts customer support and racing heritage.
