Key Features & Benefits:
- Space Saving - A unique way to make efficient use of that awkward wheel well area and shape.
- Perfectly Shaped - Not only do these tanks mold to the shape of your wheel well but the top and outside are also squared off to account for further building. Last we checked, it’s easier to build a square box than a round one.
