Samix TRX-4 Brass Hex Adapters help add a bit more unsprung weight, and add 6mm of length to your track width. The hubs weigh 5 grams each (20g total), so they add minimal rotating weight to the drivetrain. They are easy to install using the stock hardware and will help to increase the overall stability of the model.

  • 6mm thickness
  • Made of high quality CNC machined brass
  • Direct fit standard TRX-4
  • Black finish with gold chamferred edges
  • Width marked on the side for easy identification

Samix TRX-4 Brass 12mm Hex Adapter (4) (6mm)
Got these for my TRX-4 Sport, expecting to increase the track width with 3mm on each side, 6mm total. This is not the case. The sizing here refers to the thickness of each adapter, and they are actually only 1mm wider than the stock ones, adding a total of 2mm width to your car.
I've ordered the 8mm ones that will give me the 6mm I wanted.
In terms of quality, they look impeccable, and they're easy to fit. Does not come with set screw/set pin.

Very disappointed in these hexes. They are supposed to be offset a total of 6mm when each hex only adds 1mm for a total of 2mm offset.

These are an excellent addition to my TRX-6 (so I had ti buy 2 sets). The weight & increase in offset is VERY noticeable when testing out the stability. AND the wheels still fit up into the fenders under full compression (just barely)’ I highly recommend these for a “stock” appearance using stock bodies.
