  • • SAE J1128
  • • Ford (ESB-M1L85-A)
  • • Chrysler (MS-8900)



The GXL wire has a bare copper wire conductor. Copper is the most common material used in electrical wires and cables, which is mostly because it has amazing electrical properties and is cheaper compared to other metals. The stranding enhances its flexibility and enables it to carry more current.


The GXL cable has XLP insulation, which is flexible but very tough, made of a complex chain of molecules forming a sturdy polymer. It can withstand a wide range of temperatures, is resistant to chemicals and UV light deformations, water-tight, and easy to cut.
