This GPM shock absorber shaft core is specified for improved structural stiffness in TRAXXAS X-MAXX shock assemblies. Fabricated from 4140 medium carbon steel combined with aluminum 7075, the section thickness is increased from the original 5.0mm to 7.0mm to reduce flex and impact damage under heavy loads. The part fits both GPM and OEM shock bodies and provides a more consistent oil sealing interface than conventional O-ring setups, reducing the risk of leakage.
