 This is an optional K Factory 3.5mm ZF Rear Belt, and is intended for use with the Team Magic E4 family of 1/10 touring cars. A good set of belts will provide higher transmission efficiency through reduced friction. In other words, they can help the car to run faster. K Factory ZF belts are super low friction and are constructed from the highest quality material available.
K Factory engineers use unique method to construct the belt texture & a special material to form the teeth. Therefore, the belt won’t break easily & the teeth won’t wear out quickly. Additionally, to make the belts extra flexible, the belt surface is given a special treatment process to provide a higher level of transmission efficiency.
