Jeep Gladiator JT Big 7 Battery Cable Kit (2020–2024)
The Gladiator JT took everything great about the Wrangler and added a bed—finally giving Jeep owners room for both gear and bragging rights. But with winches, lighting, fridges, and air systems running off the same factory wiring, your power delivery can start to sag under load. That’s where the Big 7 Kit steps in.
What’s Inside the Big 7 Kit?
You’ve heard of the “Big 3” — alternator → battery, battery → chassis, engine → chassis. We go further. The Big 7 Kit adds upgraded runs to the starter and fuse relay box, giving your Gladiator a solid, low-resistance electrical foundation that can handle serious current without breaking a sweat.
