A friend of mine is building a kart, and looking for rear hubs/axles. Does anybody know of an off-the-shelf package (or odd combination of parts that fit together) to create the following result?

  1. Flanged connection to the differential.
  2. 4x100 bolt pattern
  3. bolt-in wheel bearing

I'm drawing a blank; anybody else have any ideas?

Price range? Wheel size/weight range for the flanges and bearings?

Money is no object as long as he doesn't get into having custom parts machined, and a little extra weight isn't the end of the world. It will weigh less than 1000 lbs., though, so beefy parts aren't required.

Assuming they are looking for CV axles to bolt to a solid spool center section for a chain drive setup?

 

Closest thing I can point to -  1st gen (BMW) Mini Cooper front wheel bearings are a bolt in unit, 4x100, and happen to share a spline pattern with late '90s-early '00s Honda Civic axles. I had a pair of these hubs and two short-side axles and a Honda D-Series trans for a golf cart/UTV project, two short axles gave about a 48" width. But those don't have flanged inner CVs, nor do the Mini Cooper axles. Perhaps the Honda diff carrier could be removed from a junk trans and mounted on bearings to be used with a chain drive.

 

The next closest solution from the minibuggy world is Porsche 930 style sandrail CV joints and axle shafts, using a Dodge Intrepid unit bearing with either a sandrail 930 mini stub outer, or a 10th gen F150 outer CV stub assembly. But this gives 5x114.3 lug pattern.
