Red Pass Through Post

The Red Pass Through Post by Quickcar Racing Products is an essential electrical distribution component for high-performance race vehicles, custom hot rods, and professional motorsports applications. This compact pass-through post serves as a critical junction point in custom wiring harnesses, allowing clean voltage distribution from battery or alternator circuits to multiple downstream components without running parallel cables through bulkheads or firewalls. Whether you're building a competition engine bay, restoring a classic muscle car with modern electrical systems, or designing a bespoke race car, this post eliminates the need for messy wire bundles and reduces voltage drop across critical circuits.

Constructed from durable red-anodized aluminum with precision-threaded stud connections, the Red Pass Through Post features a compact 3.5 x 1 x 4.55-inch profile that integrates seamlessly into tight engine compartments without interfering with headers, intake manifolds, or fuel systems. The pass-through design allows multiple battery cables or distribution branches to terminate at a single point, dramatically simplifying circuit organization and improving diagnostic accessibility during tuning sessions or troubleshooting. The vibration-resistant mounting and corrosion-resistant finish ensure reliable performance under extreme underhood conditions—from high-heat engine bay temperatures to moisture exposure on wet tracks.

This post is ideal for fabricators, engine builders, and race teams integrating custom fuel pump circuits, ignition systems, starter relays, or auxiliary lighting on vehicles with non-standard electrical architectures. Its lightweight 0.2-pound design makes it suitable for weight-conscious competition builds without sacrificing structural integrity or current-carrying capacity. Installation requires only a secure mounting point in the engine bay and proper terminal crimping to stud connections—a straightforward modification that professional shops and experienced DIY builders can complete in minutes, making it an indispensable accessory for any serious automotive electrical upgrade project.
