Firewall Bushing 2 GA

The Firewall Bushing 2 GA by Allstar Performance is a precision engine compartment component designed for builders and mechanics who demand structural integrity in high-performance automotive builds. This small but critical bushing serves as a vibration-isolating interface where mechanical systems pass through the firewall, preventing metal-to-metal contact and reducing noise transmission into the cabin. Whether you're assembling a custom engine swap, installing aftermarket hydraulic lines, or upgrading electrical harnesses, the firewall bushing ensures clean routing while protecting your firewall from abrasion and fatigue cracking.

The 2 GA designation indicates a 2-gauge wire or cable compatibility rating, making this bushing ideal for heavy-duty electrical applications or fuel line routing where dimensional precision matters. Manufactured by Allstar Performance—a trusted name in race and street performance components—this bushing is engineered from durable elastomer and metal construction to withstand engine bay vibration, heat cycles, and mechanical stress without degrading. The compact design (4 x 1.6 x 7.05 inches) allows for easy installation in tight engine compartment spaces while maintaining a secure, rattle-free fit that professional fabricators and DIY builders alike depend on for long-term reliability.

Mechanics and engine builders benefit most from stocking this bushing when undertaking LS swaps, custom cooling systems, or any build requiring multiple firewall penetrations. Installation is straightforward—simply slide the bushing over your cable, line, or harness, position it at the firewall penetration point, and secure it with mounting hardware. Its lightweight profile (0.1 lbs) adds virtually no weight while dramatically extending the service life of your wiring, fuel lines, and control cables by eliminating vibration-induced fretting and chafing. For anyone building a reliable, professional-grade engine installation, the Allstar Performance firewall bushing is a small investment that pays dividends in durability and noise reduction.
