Black Pass Through Post

The Black Pass Through Post by QUICKCAR RACING PRODUCTS is an essential wiring harness component for high-performance automotive electrical systems and race car builds. Designed for vehicles requiring clean, professional-grade power distribution, this pass-through post allows secure routing of multiple electrical conductors through firewall or panel openings without pinching, fraying, or creating shorts. Whether you're building a custom engine harness, installing an aftermarket electrical system, or upgrading a race vehicle's power delivery infrastructure, the pass-through post eliminates the risk of damaged insulation and ensures reliable current flow under demanding conditions.

Constructed from durable black nylon or polymer material, the pass-through post features a precision-engineered design that accommodates multiple wire gauges while maintaining structural integrity and electrical isolation. The compact 3.5 × 1 × 4.55-inch form factor and lightweight 0.2-pound construction make it easy to integrate into tight engine bays and custom wiring runs without adding unnecessary weight or complexity. The post's smooth internal diameter prevents insulation abrasion, a critical consideration when running high-amperage circuits where voltage drop and heat generation are concerns. Its modular design allows technicians to organize conductors systematically, reducing installation time and improving troubleshooting accessibility during dyno testing or post-race diagnostics.

Professional fabricators, drag racing teams, and engine builders rely on the Black Pass Through Post to maintain OEM-quality wiring standards in custom applications where factory harnesses don't apply. It pairs seamlessly with QUICKCAR RACING PRODUCTS' full electrical systems integration suite, making it ideal for complete vehicle rewires, fuel injection conversions, and multi-system upgrades. Installation requires only basic hand tools and takes minutes—simply route conductors through the post opening and secure it to the firewall or panel using fasteners appropriate to your substrate. For autocross, road racing, or street performance builds where reliability and serviceability are non-negotiable, this component delivers professional results at a fraction of custom fabrication costs.
