Gotcha - I wasn’t sure if you were going to machine an adapter to fit the Newbee adapter or a complete one.
@Ean.esk8 is the file for the shock pad on your newest 4GS available on here? I know it was for the 1st gen drives but not sure on the newer gen.
Totally forgot to mention - I have CNC machining capabilities so it’s more a matter of “how easy is it to adapt without reverse engineering?”
Newbee 4GS Gen 4 TPU shock absorber.stl (5.4 MB)
I’m just doing this through my phone so can’t check the model but this should be it.
Are the shock pads still TPU or has anyone had them cast in urethane?
Looks like the right part. Thanks! Worst-case scenario I can use that to build a drill pattern and then fill in the gaps that need to be milled out.
FYI, one thing I found with really deep tires is that the wheel adapter on the wheel needed to be effectively made deeper to offset the wheel further otherwise the tire would contact the gear drive body. In that photo of my 4WD board above with the 10" off-road tires, I have 3D-printed spacers between all the rims and the standard wheel adapters.
I’ve found a need for this one one of my setups as well. Would you mind sharing the file for the spacer?
Spacer for 4GS 4th Gen Wheel Adapter and Rockstar Pro II XL v7.stl (106.5 KB)
@andoug, here you go.
BTW, on my Newbee trucks with these spacers I end up having just enough thread on the axles for the locknuts. They are basically flush with the end of the end of the axle. On a customer board with Trampa IR trucks, there wasn’t quite as much as thread.
Also, to do this, I flipped the 4GS shock absorber so that the inner ring of it (that joins all the segments together) is closer to the wheel instead of closer to the gear. That gets you a few extra mm. The one thing that’s annoying with this new design of the 4GS shock absorber is that the diameter is so small that it butts up against the end of the truck hangar and prevents the drive from being moved in further towards the center of the hangar if one wants to do that. This wasn’t an issue with the previous gen.
Thanks!
What width of trucks are you running?
I’m running the Newbee 2nd gen RTKP. I think the hangar is 310mm. I can’t remember the width from axle to axle but it’s pretty wide.
I just measured the 1st gen Newbee RTKP and it’s 458mm from axle end to axle end.
@Kodin can you share the rims you’re thinking of trying to use? I suspect if you can make this work that others will be interested in this and potentially getting adapters from you.
It’ll be after May before I can get to that project; building a camping trailer up off an empty flat-bed trailer first and I just moved.
back for my quarterly request…
@Ean.esk8 thane drives soon? 
if there was a solid alternative to BN M1 they would probably sell like hotcakes
I will second this. With the elimination of radium thane belts as a viable option, my current build is probably stuck in purgatory as i need some reliable, high torque drives for ~110mm size wheels. Ideally greater than 3:1, id love if it were around 3.5:1 lol. I’ll put my money where my mouth is, if theres a set of street 4GS made that can accomplish that, count me in for four of them for my build on the spot 
also i need thane drives for the used Triplelinks i just got.
lmao good luck
Thane is such a limiting wheel choice that i wouldn’t be surprised that most who are willing to invest in gears also are willing to switch to pneumatics.
Obviously there are thane diehards out there , and to them I say just sweep the parking lot before riding in it
