Hopefully, you’ve found this page because you are looking for battery cables for a GM application. At this time, you can buy the cables used on GM and Chevy pickups, Blazers or some other single battery GM V8 applications.

We continue to add cables to our standard sizes, so if you don’t see what you need, please send us an email here.

Our heavy duty cables are made from cast copper battery terminals and 1/0 cable.

  • The positive cables feature a heavy duty 90-degree starter lug with 3/8 holes.
  • The negative cables use a standard lug.

They should work great together for any small block. (The stock cables were probably #2 gauge, so our 1/0 cables are a wire size larger.

If you have a big block, high compression or diesel engine, you might want to consider our 2/0 cables. They are also listed below.

Our ground cables come with a #4 cable for the chassis ground, much heavier than the tiny wire (#14 maybe??) on the stock wires.

We offer three (3) different types of GM cables.

  • 59 inch 1/0 side post (used on many GM V8s)
  • Cables with top post terminals for converting to top post batteries
  • Extra heavy duty top post cables

Note: The top post cables are a couple inches longer, to account for the taller battery.
