Does anyone know of any compatible parts for the Volcano STX Truck such as the front lower arms.

i think the nitro mt2 arms might but you would have to change somethings to make them work. the problem with changing arms is that the drive shaft length wont be right

the hpi mt2 steering hub and the c-hub fit on the stx

Do you know the part numbers by chance?

For the Aluminum steering hub and C-hub you'll want NMT2020 & NMT2021

here: http://www.rcmart.com/catalog/advanc...&price_range=0

You'll need a different size bearing for the outside of the steering hub.

try a search on MT2 on ebay also.

Good luck,

Mark
