This Hop-Up Option is for use with the TC-01 chassis. It helps to contribute to more efficient drive-line efficiency compared to using the kit standard dog-bone set up.

• Crafted in durable and rigid steel, this component can be used in place of kit-standard dog bone and cup parts, which provide true rotation at a range of angles for free, efficient power.
• Compatible with TC-01 chassis cars.
• Please note that this set contains parts to assemble one shaft. Two sets are required to complete the upgrade from front to rear.
