Rywire Universal Ground Kit - 4 Gauge Battery & Ground Wires

Rywire Universal 4 Gauge Battery Cable & Ground Kit

Getting voltage drop or electrical gremlins? Bad grounds are usually the culprit. The Rywire universal ground kit gives you a 20-inch 4-gauge battery ground cable and three 14-inch 8-gauge ground wires for your transmission and engine grounds. The factory ground wires corrode over time, develop high resistance, and cause voltage drop that messes with your sensors, charging system, and starter. Fresh ground wires fix that. This kit's universal, so it works on any chassis. Just bolt the grounds to your battery, transmission case, and head or valve cover.

Why Fresh Grounds Matter

Your electrical system needs a clean path to ground for everything to work right. When ground wires corrode or develop high resistance, your voltage drops and your electrical components don't get the clean power they need. That causes all kinds of weird issues: dim headlights, slow cranking, rough idle, sensors reading wrong, alternator not charging properly, all of it. Fresh ground wires with clean connections fix most of that. If you're chasing electrical issues and you haven't replaced your grounds in years, start here.

4 Gauge Battery Cable, 8 Gauge Grounds

The kit includes one 20-inch 4-gauge battery cable with ring terminals for your main battery ground. That's the big ground from your battery negative terminal to the chassis. Then you've got three 14-inch 8-gauge ground wires for your transmission and engine grounds. Run one to your front transmission mount, one to your rear transmission mount, and one to your head or valve cover. That covers your main grounding points and gets you a clean ground path.

DR-25 High-Temp Shrink

All the ground wires are covered in DR-25 high-temp shrink tubing. That's heat-resistant shrink that holds up to engine bay temperatures without melting or cracking. If you're running the grounds near hot exhaust components or you've got a turbo setup, the high-temp shrink keeps the wires protected.

What You Get

• Rywire universal ground kit
• 1x 4-gauge battery cable (20 inches, ring terminal style)
• 3x 8-gauge ground wires (14 inches each)
• DR-25 high-temp shrink tubing on all wires
• Universal fitment (works on any chassis)

Recommended Ground Locations

• 4-gauge cable: Battery negative to chassis
• 8-gauge wire 1: Front transmission mount to chassis
• 8-gauge wire 2: Rear transmission mount to chassis
• 8-gauge wire 3: Head or valve cover to chassis

Note: Universal fitment. Clean all ground contact points with a wire brush before installing new grounds. Corroded or painted surfaces don't conduct electricity well. Make sure you've got bare metal contact at every ground point or you're not getting a clean ground.
