Flexiride
This is a very similar style axle setup.
They make single wheel set ups and complete axle stuff too.
The big issue is to be sure to get a spindle that will accept the size bearings used in the cat.
Flexiride make many different weight capacity sizes.
A 2000 pound size would be optimal
A set of the cartridges that have a spindle that uses 1-3/8" inner bearing.....1-3/4" seal ride surface and a 1-1/4" outer bearing.
********UNLESS YOUR WHEELS ARE THE LARGE BEARING TYPE****** but these are normally only found on the large cats 3700....4700 *********
Get your axle out and then adapt things so the Flexiride can be attached.
I looked high and low for a front axle for my 2100......nothing decent available..
