Brought to you by Bitter End - Old School Choppers - One-Stop Shopping for Hardcore Chopper Builders.

  • Are you sick and tired of being told, "There's no way to put a 300mm tire on your Sportster?!?"  Screw that, dude!  Put that width tire on your Sporty using our all new mega-heavy-duty jackshaft offsetting kit and 300 width hardtail!!!
  • Kit features industrial quality iron pillow block bearings w/grease zerks, 1/4" grooved 1" shaft w/key stock, set screw collars, two wear-resistant 22 teeth sprockets for 530 chain, and four of our 1.5" diameter x 7/16"-NC threaded weldable slugs
  • Kit also includes 300 tire width hardtail and two 530 chains and front and rear sprocket for 1991-up XL/Sportsters and jackshaft platform material w/gussets and brake bracket.
  • In addition to the slugs being weldable into any desired alignment position, the sprockets, pillow blocks, and collars can be positioned side-to-side to suit virtually any application and alignment/offset position.
  • Pillow blocks are slotted for 1/4" of front-to-rear for adjustment as chain wears in and stretches.  (NOTE: if chain wears beyond the adjustability of the pillow blocks, cutting a link out of the chain or machining longer slots in the pillow blocks may be necessary)
  • NOTE: Only parts shown in picture 1 are included in this item.  Hardtail and platform for jackshaft kit shown are NOT included and are shown ONLY for illustrative purposes.  Hardtail shown is for 300 tire being installed on a 2004-up H-D XL, however, we can do this kit for any year from 1991-up!!
  • Message if you would like a price on sprockets for different chain pitches and tooth counts!
