About this part

Chassis Overview:

HackFab Losi Mini-B Carbon Fiber Sprint Car Chassis Conversion Kit. This kit is the result of customer demand for a carbon fiber chassis similar to the popular late-model conversions. This conversion kit, tested in several major events with excellent performance, integrates the original HackFab Bolt-On Sprint Cage and body without requiring additional purchases. Key benefits include an improved battery location with a left-weight bias, the option to add weight bars for fine-tuning, and the ability to lower the center of gravity compared to the stock aluminum chassis. The kit accommodates various battery sizes, supports larger servos, and features a wider, more open chassis plate for easier mounting of electronics and weights. Overall, this conversion transforms the Losi Mini-B into a competitive oval sprint car with enhanced handling and customization options.
