***Pre-order: Aluminum shipping in 1-2 weeks, Black Anodized shipping in 2-3 weeks***

These spindles are .26lb lighter while being significantly stronger than the stock spindles that are weak and fail frequently.

CNC machined from high strength American made aluminum billet that is certified 100% pure and tested to verify strength properties.

These are a direct replacement for the stock spindles, cost less ($340 vs $330) and match the stock geometry exactly for a perfect fit.

Smooth front profile allows these spindles to flow and cut through the snow with less resistance vs stock.

Bushings are included

See swapmeet post for pricing and link to the website for pre-order: HERE

Compatible with a 39" zbroz a-Arm?

Yes they will fit for sure...but not sure if you will still have to trim anything off to make them work or not. If you do have to trim still it will be less than with the stock spindle.

Fatigue point??

Nice product...great price point! Seems to be some of these first year AXYS-mtn spindles having issues with obstacles... early season riding can be expensive!

How sure are you about the lightening holes for the "toe" of the "shoe" that presses on the ski-rubber??

The two shown by the arrows, IMO, would be a stress riser for a high load area that could crack from cyclic fatigue over time...
but any in the foot would have me looking harder at the design.

Haha good one. :)
The sarcasm is rich on that one.

Thank you.

And appreciate the question.

We're not worried about them at all, the holes are drilled to different depths along the part to match the stress curve along that area, e.g. There is more material where there will be more stress.
Computer analysis doesn't show a problem (not that fea always predicts real world behavior perfectly )
If you saw them in person I think you'd be on board

Can they be powdercoated? (Obviously they "can" but you know is it frowned upon)

We can anodize them in most colors, but if you're hell-bent on using powdercoat for some reason you can order the aluminum ones from us and ask that we leave the bushings out so you can powdercoat them
