2019 husky fx450 front suspension

Kreft Revalve Control for the AER is a great snowbike air fork. 215Psi and cranked to Pro SX settings is really nice. it's 1000 bucks though. Same cost as the TRIO.

That said, the explor fork with valving by Brockstar and .60 springs would be a great full time snowbike fork

We have 2 guys here running just the stock fork with more pressure and clickers adjusted to suit with good results , so far none of them has blown out the seals.
If you want to spend serious money just go trio and have the base fork stock.

Bike Balance rider positioning (peg and bar set up) --- first -- set up for proper transfer on the rear end -- second --- than balance out the rest by dealing the fork. I usually start with cranking in the compression dampening first and see where it gets me to before going to heavier springs -- in your case a bit extra air is easy. If everything is set up properly you may not need crazy stiff forks.

That is just my experience. The snowlike rear end kicks like a Mule if you do not have transfer and balance right and drives all that energy straight into the front end.

If you read dirt bike Magazine and they talk about the stinkbugs feel of some bikes that is what they are talking about to tall and stiff out back overpowering the forks.
