Does anyone reproduce these? I would prefer a high speed set.

This thread from 2009 indicated that someone had just started offering new ones.

There was just a thread about a month ago that more will be made, about $2000 a set or something like that.

Try Brian Moriarty on his web page for snowmobile parts:

or

It's funny the high gears cost less than the 7:1 gears, apparently the low ratio makes sense for snowmobiles, but it is difficult to find them in good condition. I can somewhat attest to this I have a number of TT rears with the low gears and they are always worn quite a bit.

High speed worm gears have 6 teeth and not 7 as stated on the snowmobile site (4 teeth on the low speed worm). The high speed ring gears have 31 teeth and the low speed have 29.
