The 6837r steering blocks are precision machined from 6061-t6 aluminum to provide increased strength and durability compared to standard composite parts. Designed to handle the stress of high speed driving, jumping, and rough off road use, these steering blocks help maintain accurate steering geometry while reducing flex in the front suspension. The aluminum construction improves reliability while still keeping weight low for balanced performance. The anodized finish adds corrosion resistance and a clean custom look to your rc build. These steering blocks are compatible with traxxas hoss 4x4 vxl, rustler 4x4 vxl, slash 4x4, and stampede 4x4 models that use the 6837 series steering block configuration.
