Alpha aluminum trackshaft/Sidewinder steel trackshaft

[kanedog]

Are these the same design except for the reverse part of the Yammi shaft?
I want to replace the aluminum with steel.

I can’t fully confirm on the ascender 2 stroke chassis, but the track shaft is the same between the proclimb 2 stroke and the proclimb 4 stroke / King Cat in the ascender chassis...

according to the parts fiche the sidewinder still uses the old style snap ring on the brake side and the 2018+ cats use the double nuts. im sure you can swap them and use the snap ring but cant say for sure
