Ring Terminal 3/8in 2 Ga w/Heat Shrink 20pk

The Ring Terminal 3/8in 2 Ga w/Heat Shrink 20pk from QUICKCAR RACING PRODUCTS is the go-to solution for high-amperage electrical connections in performance vehicles, engine swaps, and custom wiring harnesses. Whether you're upgrading a fuel pump circuit, rewiring a battery distribution system, or building a full race harness, these terminals provide the secure, corrosion-resistant connections that demand absolute reliability under load. This 20-pack delivers enough terminals for comprehensive electrical work without requiring multiple purchases, making it ideal for shops, fabricators, and serious enthusiasts tackling major electrical modifications.

Engineered for 2-gauge wire, these copper ring terminals accept a 3/8-inch stud and feature integrated heat shrink tubing that seals the terminal-to-wire junction against moisture, vibration, and electrical degradation. Tin-plated copper construction resists oxidation far better than bare copper, ensuring lower contact resistance and longer service life in underhood environments where humidity and heat accelerate corrosion. The heat shrink design eliminates the need for separate adhesive-lined tubing, streamlining installation while providing superior moisture barrier properties that protect against white corrosion at the crimp point—a common failure mode in high-vibration applications and motorsport duty.

These terminals are essential for battery relocation kits, alternator upgrades, high-amperage fuel pump systems, and engine bay rewiring on street rods, race cars, and restorations. Install using a proper 2-gauge crimp tool to ensure full contact area—undersized or hand-crimped connections will fail under full-load conditions. The 3/8-inch eyelet diameter fits standard battery terminals, relay blocks, and fused distribution panels common in automotive and marine electrical systems. For anyone serious about electrical reliability in modified or performance vehicles, the Ring Terminal 3/8in 2 Ga w/Heat Shrink 20pk delivers professional-grade connections that won't compromise your build.
