Round Oil Tank for Custom Use, 3.5 quart.

Round Oil Tanks for Custom Use - Side Fill, 3.5 quart - Hardbody

If you are after that traditional chopper look, then this rubber mounted steel 3.5 quart oil tank with a battery tray is the perfect choice. With a side fill cap, they are manufactured from 16 gauge steel to resist cracking and 100% TIG welded for maximum strength. Each tank includes a heavy duty front mount and a chrome fill plug. These tanks use a Softail size battery and our M83548* OE style rear tank mount. For best results use our M80627* rubber mounts and 10807 battery cushion. Designed in this tank is an extended internal oil return tube that dumps the hot returned engine oil to the far left side of the oil tank. This keeps the returned oil as far away from the feed line as possible, creating an efficient circulating effect. A lower left hand relief has also been built in that can be used with a chain or belt drive. This tank measures 11 3/4" long and has a 6 1/2" O.D. Fits all HARDBODY FAT-A-TUDE, chopper style and rigid frames. Also fits OE Softail frames 1984/1999 if a front horseshoe type mount is fabricated and welded to the seat post. Chrome Plated.

Winged horseshoe oil tank for wide tire Softail and Fat-A-Tude rigid frames.  Made in the USA by Kraft Tech. Chromed.

Winged Horseshoe Oil Tank for Wide Tire Softail and Fat-A-Tude Rigid Frames - Hardbody by Kraft/Tech

Due to the additional width of our HARDBODY Wide Tire Softail Frames, a standard width Winged Oil Tank would interfere with the action of the rear fork. WE now offer these steel side fill winged oil tanks to fit your Wide Tire Frame, in your choice of a chrome plated finish or a raw steel finish. A chrome plated fill plug is included with both oil tanks. These oil tanks hold slightly over 3 quarts of oil and can be used with any 1984/1996 Softail style battery. A special feature of these tanks is the Internal Oil Routing. Rather than dumping the hot returned oil near the feed line like most oil tanks, our oil tanks dump the returned oil to the far left side of the tank as far away from the feed line as possible. This internal line separation method creates an extremely efficient circulating effect producing cooler oil temperatures.
Chrome plated. Made in USA.

Custom Horseshoe Oil Tank for Big Twin 4 Speed - Hardbody by Kraft/Tech

These 3 1/2 quart side fill horseshoe oil tanks are chrome plated without the oil filter option (for remote filter).
