Based off of our Flagship GMT400 Aluminum Coolant Reservoir (Unpressurized), this low-profile surge tank has been slimmed down and can be used in alternative applications such as with Slosh Tubz fenders or other low-clearance options on lowered trucks. Surge Tanks are designed to be used with coolant systems that DO NOT have the pressure cap on the radiator.
