Overview
Reinforce your front suspension with the Hot Racing Aluminum Front Axle Carriers with Bearings. CNC-machined from aluminum and finished in clean black anodizing, these heavy-duty front steering blocks replace the Arrma AR330403 or AR330505 stock front steering blocks with a race-grade alternative built to handle the punishing loads of 1/8 BLX brushless driving on the Kraton, Notorious, and Outcast platforms.
Featuring 4mm carbon fiber steering arms, aluminum hub nuts with Delrin cups and O-ring position locks, and oversized heavy-duty rubber-sealed bearings, these axle carriers are a comprehensive front-end upgrade in a single bolt-on package — perfect for aggressive bashers and competitive drivers alike.
