  • Regular price $410.00


Your steel frame rail is a very poor conductor of ground current.  The American Autowire All Copper Grounding Kit eliminates the framerail as a conductor a by using three grounding boxes connected by 6 gauge copper cables. The ground "loop" attaches to your existing negative battery cable to make for a solid, continuous connection.

Includes 20 coils of pre-labeled wire, terminal lugs and a 6 gauge crimping tool.
