Pacer Red 4/0 AWG Battery Cable - 100'

The Pacer Red 4/0 AWG Battery Cable – 100' is purpose-built for high-amperage automotive electrical systems, delivering the robust copper conductivity required for engine starts, auxiliary power distribution, and custom vehicle wiring. Whether you're upgrading a street rod with an oversized alternator, installing dual batteries for a heavy-duty truck, or rewiring a classic restoration project, this cable handles the current demands that factory wiring cannot sustain.

At 4/0 gauge (107 mm² cross-section), it ranks among the thickest automotive cables available, making it the go-to choice for professional mechanics and serious enthusiasts tackling performance electrical modifications. Four-ought gauge copper carries extreme amperage loads with minimal voltage drop over extended runs, critical when battery-to-starter distances exceed standard factory lengths or when auxiliary loads demand dedicated supply lines. The Pacer Group's red polyvinyl chloride (PVC) jacket resists oil, abrasion, and UV degradation—essential properties in engine bays where heat cycling and chemical exposure degrade lesser cable insulation.

With 100 feet of usable conductor per spool, you gain flexibility to route power through frame rails, under body panels, or to remote battery banks without mid-run splicing. The genuine copper mass ensures long-term reliability, making this cable an excellent choice for those who demand the best in performance and durability.
