Engineered for the Traxxas 1/8 4WD Sledge Monster Truck, these shock caps are produced from 7075 alloy to provide superior mechanical strength and accurate thread engagement. The cap enhances the interface with the oil pressure cap to improve oil sealing on both GPM and original dampers, reducing maintenance frequency and supporting consistent damping under higher pressure conditions. This component is intended as a performance oriented upgrade to strengthen shock assemblies and improve longevity in demanding use.
