I read that the holz are not designed properly in that they don't let the sled steer fully in both directions. I also read that they have been redesigned so they may or may not have been fixed. there was another guy that bent the holz spindle but who know what really happened in his case, at any rate it should not bend.
As for the ARS FX, i read that the fit and finish is excellent and achieve better ride quality as well as easier steering. I think they look better and look more durable than holz too.
I have seen pics of guys with 07 sleds getting aftermarket spindles so there must be room for improvement. Stock spindles are still pretty expensive. I think they are approximately 150 a spindle. Don't quote me on that price.

Why did you choose these spindles over any others (Holtz, 07-08 Polaris)? I have a set of Razors to go on mine and have been looking into spindles myself. Hate the to spend the $$ without some idea of how they work.
