HPI Super Star question

Post by TRX-1-3 »

These are listed as "for JRX2". Does anyone know did HPI make wheels for specific applications or are these "universal" if using the HPI bearing/wheel adapter set(s)? If I track down the adapters, could I slam these on a TRX series buggy?

My TRX-1 came with HPI wheels. The TRX-1 metric bearings are much bigger than the JRX2 front bearings. To adapt the JRX2 front wheels, the bearings would need a 9.5mm outer diameter (perfect wheel fit) or smaller (bearing adapter needed). The 11mm bearing is way too big. I see 5x9x3mm bearings on Amazon. Those could fit with a thin adapter.

The TRX-1 wheel is 10mm between the sides of the bearings, and the JRX2 wheel is wider at about 11.6mm, so the JRX2 wheel needs longer front axles.

Yes, the HPI Super Stars are typically universal and come with bearing adapters for different vehicles. HPI #6115

Thanks Gentlemen. I picked those up and an adapter set. Almost positive I'll need the "Tamiya" bearing collar. My plan is to Easy Off the chrome and dye them black. We shall see....
Hope you're doin' something fun.

Soak them in a strong degreaser, chrome will come off.
