2011-2022 Ford 6.7 Powerstroke Big 3 Upgrade & Battery Terminal Kit

The 11-22 Ford 6.7 Powerstroke Big 3 & Driver's Side Terminal Kit is engineered to address factory electrical limitations and battery terminal degradation common to this platform. This comprehensive upgrade combines enhanced grounding architecture with premium battery terminal replacement. The Big 3 upgrade significantly improves electrical system efficiency by adding dedicated ground paths from the alternator case and frame—components absent in factory configurations. An additional 1/0 gauge alternator cable with integrated megafuse further optimizes charging performance and system reliability. Construction utilizes marine-grade, tinned oxygen-free copper wire paired with adhesive-lined heat shrink tubing, tinned copper lugs, and heat and abrasion-resistant Techflex loom. This combination ensures durability and longevity across demanding operating conditions. The driver's side battery terminal replacement resolves corrosion and terminal failure issues while restoring electrical integrity. Two terminal options accommodate both factory-equipped batteries with caps and aftermarket batteries without caps—Moroso billet terminals for standard applications and 5-lug billet terminals for upgraded batteries.

Installation requires crimping new lugs onto existing cables; all necessary components including lugs, heat shrink, and tape are provided. A crimper tool must be sourced separately.
