The aFe POWER BladeRunner GT Expansion Tank offers a premium upgrade to the factory expansion tank in your Dodge Charger/Challenger. Say Goodbye to the aging plastics of the stock tank, susceptible to yellowing and brittleness over time, affecting both appearance and reliability. BladeRunner GT Expansion tanks are crafted from 1/8" thick aluminum plates for superior durability and longevity when compared to factory tanks. The incorporation of billet aluminum fittings eliminates weak points, ensuring a secure, leak-free connection.

This tank is 100% TIG-welded for proven strength and durability as well as providing a smooth, high-quality finish. Attached using high-temp stainless-steel fittings, the sight tube allows for quick, accurate filling and monitoring of fluid levels. With a straightforward installation utilizing all factory connections, the BladeRunner GT Expansion Tank effortlessly bolts into the original location. With a sleek brushed finish, laser-etched aFe POWER logo, and a raw aluminum finish, the BladeRunner GT Expansion Tank not only elevates the overall look but also allows for easy customization. Say goodbye to the hassle of covers that simply conceal the issue.
