Engineered to increase service life on the Traxxas XRT 8S, the GPM XRTDP shaft core kit pairs 4140 medium carbon steel with 7075 aluminium for enhanced resilience. The shaft diameter is stepped up from 5.0mm to 7.0mm to reduce the chance of bending or damage during hard use. It installs into both GPM and original shocks to refine suspension behaviour and longevity.
