aFe POWER BladeRunner GT Aluminum Coolant Expansion Tank for 2011-2023 Chrysler 300, Dodge Challenger & Charger (46-51003)

Fits select 2011-2023 Chrysler 300, Dodge Challenger, and Dodge Charger models. The aFe POWER BladeRunner GT Series expansion tank replaces the prone-to-failure factory plastic unit with a durable, high-capacity aluminum reservoir designed for longevity and performance.

Constructed from 1/8-inch thick aluminum plates, this tank is 100% TIG-welded to eliminate the yellowing and brittleness common in aging OE plastic tanks. To ensure a leak-free system, the tank features CNC-machined billet aluminum fittings and high-temperature stainless steel hardware. A built-in sight tube provides a quick visual check for coolant levels without needing to remove the pressure cap. Designed as a direct bolt-on upgrade, it utilizes all factory mounting points and is compatible with the original equipment expansion tank cap.
