Description

Made from TIG welded 6061 aircraft-grade aluminum, this coolant reservoir is pressure tested for maximum strength, exceeding the durability of factory plastic tanks. Its aluminum construction aids in heat dissipation. It utilizes the factory cap (included) and features a sight glass for level inspection. Some cutting of the battery tray is required for fitment. Manufactured at Sinister Diesel's Sacramento facility, it's available in Sinister Gray or Sinister Blue and offers 40% more coolant capacity than stock.
