Stinger SPD511 PRO 4 Gauge T Distribution Block

Stinger SPD511 PRO 4 Gauge T-Style Solid Brass Power Distribution Block with Shoc-Krome Finish and Acrylic Cover

The SPD511 from Stinger is a PRO series 4 gauge T-style power distribution block constructed from solid brass with a Shoc-Krome finish. Designed for car audio amplifier power distribution and a wide range of automotive and 4WD accessory applications, it uses grub screw allen key fittings to lock 4AWG cable securely at each port and includes a clear acrylic cover and silver-backed acrylic mounting base. A lifetime warranty against manufacturer defects is included.

Product overview

Stacking multiple ring terminals on a single post is a common but unreliable approach to power distribution in vehicle installations. The SPD511 replaces this with a solid brass T-style distribution block that locks each cable individually via grub screw allen key fittings, providing a secure and reliable connection at each port that remains stable under vibration. The solid brass core with Shoc-Krome plating delivers superior power transfer and corrosion resistance suited to demanding car audio and accessory applications.

The T-style form factor provides a compact, structured layout for the input and output connections. The SPD511 is designed for 4AWG cable with an 8mm diameter and covers car audio amplifier installations as well as air suspension, air compressor, 4WD accessory, and battery power management applications. The clear acrylic cover protects the terminal connections while the silver-backed acrylic mounting base provides a secure installation platform.
