HPI Brake Hub (Alloy Cast/Silver) Savage 4.1 3.5 86318

HPI Savage truck owners can upgrade to a cast alloy brake hub using this option part. The alloy construction allows the hub to dissipate heat and prevents the hub from melting at high temperatures. It will also make the drive train more durable. This hub is a heavy-duty direct bolt-on replacement for the stock plastic brake hub.
