Just curious why you guys didn't go with a one piece housing with a diff cover? More expensive? Weaker?
Because of the overall design, it needed to be a two part axle.

Setup for clockable knuckles?
Right now, it looks like if you shorten the uppers to get the caster, you'll be driving the lower link mounts into the ground? So couldn't the lower link mounts be molded to 18* as well to help with this? Or am I totally missing something? Shortening up the uppers for good caster affects link geometry.
On facebook you stated these are very difficult to engineer because of the mold. I'm assuming that's because the link mounts point in the opposite direction to the pinion output. My thought was why not make the centre pumpkin a seperate item and then the axle tubes can be slid on the pumpkin much like lockouts etc. That way you could just make a single pumpkin then make different length axle tubes to get both scx10 and wraith width etc.
If the lower links stay the same and the uppers are shortened to gain caster, the axle rotates clockwise and turns everything that way because the pivot point is the lower link bolt. Which causes the lower axle mounts to be lower than the axle housing. Not a huge issue though.
I believe, various chassis shock mounting locations does not affect link geometry, only the rate of the shock springs (Rising rate vs falling rate).
IMO, gaining caster is best achieved through c-hub/knuckle rotation. Just my opinion though. The axles look good, so best of luck on their performance and sales.
Yes, clockwise/counter clockwise is different from each side and I was thinking looking at from a drivers side as you have shown. My main concern, as you have pictured, is now the rod ends will be one of the first things to to hit the rocks, let alone the link geometry changes. The TKO design has gained pinion angle, which is already protected by the lower links but now the link mounts are going to hit stuff quicker.
Why not just design the lower link/shock mounts at an angle, like the pinion angle and clock the chubs for caster adjustments? Then you won't have to worry about shock or link geometry changes that were affected by caster changes. Just seems like more work and more things to fix if you just shorten the upper links.
Again, just my opinions and thinking out loud here.
I understand what you're saying now. The TKO can be mounted with zero clocking in which case the the lower link mounts will sit completely horizontal just like the SCX; the end user can either clock the axle and/or use aftermarket knuckles to gain caster...this design gives the option to do this without the driveshaft being angled below 90 degrees.
One of the main benefits of this design is where the pinion interfaces the ring gear. It's above 90 degrees which greatly reduces torque twist.
I like, but I don't think I'd want to give up my 8 degree kingpin angle. Are these the only C's and knuckles that will work?
