QuickCar 4 Gauge Battery Wiring Kit with 50-022 Switch Panel 50-231

A reliable electrical system is the foundation of any high-performance build, and OEM harnesses often fall short under racing conditions. The QuickCar 4 Gauge Battery Wiring Kit consolidates everything you need into one complete solution—eliminating voltage drops, reducing installation time, and giving you the confidence that your electrical system can handle continuous high-demand operation. Whether you're running a race car, a heavily modified street machine, or a dedicated track vehicle, this kit delivers the durability and current-carrying capacity required for consistent performance.

The 4-gauge fine-stranded rope-lay copper wire minimizes resistance while the 220°F+ insulation handles the heat cycles and fluid exposure inherent to racing environments. All necessary components ship together—battery switch, starter solenoid, wiring harness, ring terminals, heat shrink, and clamps—so you're not hunting down individual pieces or making compromises on quality.
