Overview
Get race-grade front-end durability for your Arrma 1/5 Kraton 8S with the Hot Racing Triple Bearing Support Steering Blocks. CNC-machined from aluminum and finished in black anodizing, these heavy-duty axle carriers replace the Arrma ARA330558 stock front steering blocks and ARA340158 steering arms — featuring triple bearing support, double-lock ball hub nuts, and 5mm carbon fiber steering arms in a single comprehensive front-end overhaul.
The standout feature is the third bearing — a 12x24x6mm rubber-shielded middle bearing — added inside each steering block to reinforce the existing stock outer and inner bearings. The result is a triple-supported steering pivot system that can withstand the massive forces generated by 8S brushless driving on the Kraton platform.
