TRX4 wheel fitment info

So the portals on the TRX4 create some challenges with fitting some wheels, they purpose here is to show what works and what doesn't. We all know the internet reaction will be fair and reasonable when someone buys wheels that don't fit a Traxxas product. :roll:

Things of note:

1: The TRX4 axle is 6 mm that steps down to a 4 mm thread. Wheels that have 5 mm axle holes may not fit all the way on the axle as there is a little part of the 6 mm portion of the axle that extends past the hex.

2: Internal beadlocks with a dished back ring (such as Vanquish, some SSD, and RC4WD steel wheels) have the most clearance on the inside. You can run any SLW hub (down to Locked Up .185 hubs) and have plenty of clearance.

3. External beadlocks and internal beadlocks with flat rear rings will most likely need wider hubs to clear the portals, the minimum hub size will depend on the ring design and inner diameter.

On to the pictures:

Incision Methods - These barely clear the portal with the #3 hub, I would suggest these as the smallest hubs to use.

SSD steel wheels - Plenty of clearance, run any size SLW hub (shown with .475 hubs). The stock hubs will not fit all the way on to the axle shaft.

Vanquish KMC Bullies - Plenty of clearance, run any size SLW hub (shown with .185 hubs).

Super Shafty Uber Hafties - Some clearance issues with these, .475 hubs with Beef Patties provided nearly enough spacing to clear but the rear ring screws contact one of the portal screws. Switching the hardware to button heads may be enough to stop the contact, otherwise I would say .475 hubs with .100 spacers would be the minimum amount of hub offset you could run.

Gmade steel wheels - These fit surprising well, they fit over the wider part of the axle and have plenty of clearance. A good choice to narrow up the track width of the truck.

RC4WD steel wheels - These do not fit all the way on to the axle shaft, drilling of the hub or filing down the axle shaft would be required. You can see they barely engage the hex hub without modification. Otherwise, the clear the portal easily.

GCM 1.9 8 holes - Do not fit all the way onto the axle shaft but do clear the portal. Modification would be required for proper fit.

Ebay Dick Cepek knockoffs - Do not fit, the rear ring contacts the portals badly and doesn't fully fit on the axle shaft. This may be the case for many of the fancy RC4WD wheels as well.

SSD 1.55 steel wheels - The stock hub does not fit all the way onto the axle but clear the portal.

That is all I have for now, other owners are free to add their findings. "thumbsup"

Update: More wheels!

Gearhead 12 Pack - In narrow offset, they clear everything easily. (Can you tell these are the wheels I'm running :mrgreen:)

Motoworx 9 hole SLW versions - Very tight fit but do clear, clearance is similar to Locked Up wheels shown below. These wheels are shown with SSD hubs which are pretty close to .225 SLW hubs.

Axial 8 hole - These particular wheels had a hex glued into them that didn't really fit the TRX4 axle so I had to eyeball this one. Clearance looks to be very tight, some rubbing of the portal case may occur around the rear ring screws.

Point of clarification on SSD wheels:

If your wheels came with hubs that fit wraith hexes like these, they will fit on the TRX4 axle.

If they came with hubs that fit a flat face hex like these, they will not fit on all the way.

Most of their wheels come with the hub to fit wraith hexes now but some do not (like 1.55s and older 1.9 steel wheels).
 
Wow!

Great info and thank you for taking the time to do this.

Really surprised about the gmades. I have a set lying around waiting for a never ending project to finish. Might have to put some tires on them.

You woldn't happen to have some 1.9 axial 8hole beadlocks around to test fit?

Good info, we will be releasing spare hubs for Wraith style hexes soon.

Thanks
 
Hi SSD, I used a set of ssd hexes from 2.2 steelies with my locked up rc wheels. Just so you know, you already make compitable hexes.

Thanks for the info. Can you describe the difference between the wraith hexes and standard flat face hexes? From looking at the pictures the hex female fitting on the wheels looks similar.

With respect to the TRX4, the main difference is the size of the hole in the hub for the axle to pass through. The hub meant for the wraith hex has a much larger opening allowing it to fit over the 6 mm portion of the axle on the TRX4.
 
Awesome post, answered some questions I had. Was glad to see the clarification on the SSD wheels since I just ordered another set that I plan to use in one of these trucks.
 
Locked Up RC wheels will fit as well.

These are pictures from Clay@ Carterfab with one of our SLW wheels using a .225 and then our .185 SLW hub.
The .225 have more room of course, but both fit.
* Depending on which .185 version you have you may need to chamfer the inside of the hole the axle pokes through. I'll confirm this asap.


Until we have our truck in hand I can't really say if our 8L or AO8 wheels will fit.
I suspect the 8L will need the center hole to be slightly enlarged do to the portion of axle shaft that is 5mm.
That would be easy to do at home and would not impact the centering of the wheel on the axle.

For AO8 wheels, we will likely need a tweak to the flanges, but that's not a huge issue to get done.

Anyway, here are the SLW shots from Clay.

Thanks i saw this and couldnt wait anymore so i had to spend $200 for a set of lockeduprc iconic wheels and proline tires!! Lol love the look!! Can someone tell me does a heavier wheel and tire help wjth wheel hop or no?

I just put lockedup iconics slw with .185 hubs on mine but i dont think the ao8 will work cause i think you need the stock hex ( which is aluminum) to space the driveshaft comming out of the portal. By the way love the wheels and with hyrax tires i cleaned 2 loops of my course in the wet which i couldnt do with stock tires.

We will have to make something for that then!

Had to drill the hole in these wheels. But I got them used and was told they are just cheap rc4wd steelies. So correct me if I'm wrong. But once drilled they leave plenty of room for the portal.
