ST Racing Concepts Traxxas TRX-4 Brass Rear Inner Portal Drive Housing (Black)
Nice quality brass product, however I already had all of the Samix brass axle/portal parts and these didnt mate up perfectly with the Samix brass outer portal covers. I had to dremel a few areas on the small inner lip to get the to sit together flush. Not sure which company was a little bit off, but either way with a little bit of work I got them to fit nicely, and now i have zero plastic on my axles. Yeah Racing alloy housings and everything else is brass. So much weight down low the performance is far better than stock..
