.9 24v Cummins 2/0GA Battery Cable Kit – Big7Kits (RAMG2-9802-20G-59DIESEL)

Upgrade the electrical system on your 1998–2002 Dodge Ram 2500/3500 with the 5.9L 24-valve Cummins using this complete Big7Kits 2/0 gauge battery cable kit. Factory cables degrade over time from corrosion, heat, and age, leading to slow starts, voltage drop, and unreliable charging. This premium “Big 7” kit replaces the weak factory wiring with heavier pure copper cables for stronger current flow, faster starts (especially in cold weather), improved charging efficiency, and greater overall reliability.

Why Choose This Kit

• 2/0 gauge pure copper construction — Fine-strand, SAE-approved pure copper (no copper-clad aluminum) for maximum conductivity and minimal resistance.
• Full “Big 7” upgrade — Covers the critical power and ground paths (far more comprehensive than a basic Big 3).
• Faster, more reliable starts in all conditions and better charging system performance (helps prevent passenger-side battery overheating issues common on these trucks).
• Ideal for stock trucks that need a durable upgrade, cold climates, or vehicles with (or planning) high-draw accessories such as winches or auxiliary lighting.
• No alternator upgrade required — These cables deliver better-than-factory performance on their own.
• Professional-grade build: Electromechanically crimped solid copper lugs sealed with marine-grade adhesive-lined heat shrink (MIL-I-23053/4) for superior corrosion and environmental protection.
• Military-style corrosion-resistant battery terminals and clearly labeled ends for straightforward installation.

Kit Includes

• Battery Negative to Fender Grounds (4GA)
• Battery Negative to Engine Block Grounds (2/0)
• Battery Negative Frame Grounds (4GA)
• Battery Negative Aux Grounds (6GA, if needed)
• Alternator Lead (2GA)
• Battery Positive to Starter (2/0)
• Battery Positive Crossover Cable (2/0)
• Battery Positive to PDC / Fuse & Relay Box (4GA)
• Fuse block with additional fuses
• 2 sets of military-style battery terminals

Fitment: 1998–2002 Dodge Ram 2500 / 3500 with 5.9L 24-valve Cummins diesel (2nd Gen).

Gauge guidance: 1/0 is sufficient for many stock applications. Choose this 2/0 version when you want extra capacity for future accessories, extreme cold weather operation, or maximum future-proofing.

Restore full electrical performance and eliminate the weak links in your Cummins charging and starting system with a true Big 7 upgrade built to outlast the truck.
