The plastic housing on the domino throttle assembly on my txt feels really cheap. I'd like to replace it with a aluminum/metal option if available?

Surprisingly, that assembly is very durable. I have been riding trials for 50 years now and that is better than any metal one we ever used. So throw a spare throttle assembly in your kit as they are cheap. The only thing that ever breaks alot is that little cap on top.

 Ps do not overtighten the bolts.

Agree👍 They are surprisingly durable. A replacement is not the first thing I would look for. Go for the Domino and as said previously,  do not overtighten the bolts.

10-4, thank you gentleman. I'll pick up an extra housing for a spare.
