Nylon wheel option for 81-018

Thanks for reaching out to us! We unfortunately don't have a nylon-wheel option for the 81-018 anymore. We did some years ago, but it was discontinued and our stock ran out not long after.

That said, if you have an aluminum track then I think the steel wheels will be okay. If you did want to opt for nylon wheels anyway then you could always manually install something like our 81-228 along with the 81-310 axle repair kit.
