KM Racing have new option parts for the H-K1 200mm nitro car available in the form of spring steel rear dogbones and two new middle shafts. Starting with the dogbones, the parts are made from high-quality spring steel and are heat-treated to make them stronger and longer lasting. The red steel parts come laser-etched for easy identification and are a direct replacement for the stock driveshafts. The second new part is a hollow hardened steel middle shaft. The lightweight axle is suitable for pin-type and screw-type pulleys and offers the same design as the EVO2-485A HK485Ti-V2 parts. Last but not least comes the titanium middle shaft made for the screw type pulleys HK460-16TV2 and HK460-23TV2. It can be used with pin-type pulleys though and is of very low weight while offering exceptional durability thanks to the titanium material used.
