The Reservoir II kit is an alternative mounting location for your ww reservoir. Roto-Fab designed this new WW relocation kit to mount to factory locations (with no cutting, drilling or modifying your vehicle necessary) between the driver's side inner fender and brake fluid reservoir. This kit was designed to provide an alternative to our existing WW relocation kit. Easy installation with our detailed step-by-step instructions! The removal of the left front tire is necessary for installation. Capacity is just under a half gallon.
