For wide tire Softail and Fat-A-Tude rigid frames. Due to the additional width of the Hardbody wide tire Softail style frames, a standard width Winged Oil Tank would interfere with the action of the rear fork. This oil tank will now fit your wide tire frame. This oil tank holds slightly more than 3 quarts of oil and can be used with any 1984-1996 Softail style battery. A special feature is the internal oil routing. Rather than dumping the hot returned oil near the feed line like most oil tanks, this one dumps the returned oil to the far left side of the tank as far away from the feed line as possible. Fits all Hardbody Wide Tire Softail style frames.
