For Sale: Unimounts

I have four of these.
Two were taken off a kart and have axle bearings.
And two are N.O.S. less the axle bearings.

$450.00 each

The uni-mount without the bearing appears to be for a 1-1/4 inch axle, the bearing for that uni-mount is a Timken YA 103 RR2, the one inch uni-mount bearing is a Timken YA 100 RR

louie,

You are correct. I never noticed the difference.
The one with the bearing has an O.D of the bearing of 2in.
And the without the bearing has an O.D of the bearing of 2 & 3/8in.
I don't know if a differant bearing could be used to set it up for 1in axle.
Also, would the one for the larger bearing be worth less $$ ?

Rich, the mount for the 1-1/4-inch axle is rarer that the smaller mount, I would think it is more valuable, but it's whatever price that you are happy with, take it.

Louie, got it right,

The 1 1/4" mounts were used on the J and K series American karts with the splined knock off rear axle.

A sleeve could be put in to drop it down to 1" though.
