Stinger SPT5118 8 Gauge PRO Series Boot Fork #8 Spade Terminals

Stinger SPT5118 PRO Series 8 Gauge Fork Spade Terminal 4 Pack with 2 Red and 2 Black Platinum Finish and Black Boot

The SPT5118 from Stinger is a PRO series 4-pack of 8 gauge fork spade terminals in platinum finish with black boot, supplied as 2 red terminals for positive power connections and 2 black terminals for negative ground connections. The fork spade design provides a secure, removable connection at distribution blocks, amplifier terminals, and stud connections without requiring the fastener to be fully removed for disconnection.

Product overview

Fork spade terminals provide a practical alternative to ring terminals in installations where connections may need to be serviced or reconfigured without fully removing the retaining fastener. The SPT5118 uses the same PRO series platinum finish and black boot construction as the broader Stinger terminal range, delivering a premium custom installation appearance suited to high-end car audio builds.

Two red and two black terminals are included per pack, covering two complete positive and negative connection sets. The black boot covers the crimp section of each terminal, providing insulation at the wire-to-terminal transition and a clean, finished appearance in the installation. A crimp tool suitable for 8 gauge terminals is required for correct installation.

Features and benefits

8 gauge fork spade terminal: Designed for crimp connection to 8 gauge power and ground wire, providing a secure and removable connection at distribution blocks, amplifier terminals, and stud connections.

Platinum finish: The platinum finish provides a premium custom appearance suited to high-end car audio builds where terminal aesthetics are part of the overall installation standard.

Black boot insulation: The black boot covers the crimp section of the terminal, providing insulation over the wire-to-terminal transition and reducing the risk of short circuits from exposed metal at the crimp joint.

4-pack with 2 red and 2 black terminals: Two red terminals for positive power and two black terminals for negative ground, providing two complete matched pairs for dual amplifier or dual accessory power and ground connection sets.

Fork spade design for removable connections: The fork spade (fork terminal) design allows the terminal to be removed from a stud connection without fully removing the retaining nut, making it practical for serviceable installations.

Frequently asked questions

What is a fork spade terminal?
A fork spade terminal is a flat, U-shaped terminal that slides over a stud or post and is secured with a nut. Unlike ring terminals which require the fastener to be fully removed for disconnection, fork spade terminals can be removed and re-attached without fully undoing the retaining nut, making them practical for installations where the connection may need to be serviced or reconfigured.

What is the difference between the SPT5118 fork spade and the SPT5108 ring terminal?
Both are 8 gauge PRO series terminals for car audio power and ground connections. The SPT5108 is a ring terminal where the ring fully encircles the stud, requiring the nut to be removed for disconnection. The SPT5118 is a fork spade terminal that slides over the stud from the side, allowing removal without fully undoing the nut. Ring terminals are generally preferred for permanent high-current connections, while fork spade terminals suit serviceable connection points.

What does the black boot do on the SPT5118 terminals?
The black boot covers the crimp section of the terminal, providing insulation over the wire-to-terminal transition and reducing the risk of short circuits from exposed metal at the crimp joint. It also provides a clean, finished appearance in the installation.

Do I need a crimp tool to install the SPT5118 terminals?
Yes. A crimp tool suitable for 8 gauge terminals is required for correct termination. Contact us if you need guidance on selecting the correct crimping tool for these terminals.

Are the SPT5118 terminals suitable for positive power connections as well as ground?
Yes. The pack includes both red terminals for positive power and black terminals for negative ground, covering both polarities. For professional installations, use red for positive and black for ground to maintain standard polarity identification throughout.
