Dee Zee's L-shaped transfer tanks are forged out of rugged steel, protected by black NRT rust inhibitor powder coat finish for rugged quality that lasts. Dee Zee's L-shaped transfer tanks are constructed out of heavy-duty 14 ga steel with a radius curve design to eliminate key weld pressure points. Three internal baffles add stability by preventing fluid from sloshing around the tank when turning or stopping during driving. Hammerhead design with narrow base ensures the tank fits easily between wheel wells, tucking underneath your crossover toolbox saving some of your truck bed space for hauling cargo. A lockable cap keeps your tank content secure, while a 0.375 in drainage plug and venting coupler allow easy drainage of contents when needed.
