From their website:

Our cables are built from cast copper terminals using 2 gauge or optional extra heavy duty (XHD) 1/0 (“one-aught”) SAE SGT battery cable for the starter and engine block ground and #6 (or #4 gauge with XHD option) wire for the fuse block or body ground wires. This is larger than the stock wire to lower resistance and improve cranking. A high temp SGX wire is also optional. We seal the connection with heavy wall adhesive lined heat shrink. In the picture at left, compare the thickness of the wires. Note the stock cable doesn’t have any heat shrink sealing the connection. Anti-corrosion bolts and battery washers are also included.

All the positive cables come with a starter lug cover. Covers for the battery terminal ends are available for an extra $5 each.

Fuse block cables are larger wire with heavy duty ends for lower resistance (#4 wire shown).

The stock 2-hole fuse block connector has the battery cable and the alternator wire ganged together. We replace that by separating the wires and putting a heavy duty 90 degree end on each one. Together, the 2 cables work to replace the goofy Jeep 2 hole connector.

The result -A perfect fit!

The Wrangler cable set includes a positive battery cable with starter lug cover, negative battery cable, an alternator cable with fuse link, anti-corrosion battery washers and anti-corrosion battery and terminal ends.
