Black Front Spindle Steering Blocks for Boost/Circuit/Ruckus/Torment (2) (RPM73292)

RPM Oversized Front Spindle Blocks (pair) for 2WD ECX models such as Boost, Circuit, Ruckus, Torment and AMP. They upgrade the front suspension by using larger 5x11x4 mm bearings (sold separately), boosting load capacity and fatigue resistance for stronger performance and longer life than the stock blocks.

Made from durable nylon, these blocks preserve stock geometry for a straightforward, drop-in swap. The larger bearings translate to improved front-end performance while maintaining OEM mounting compatibility. Bearings are sold separately, and RPM backs these parts with a limited lifetime warranty against breakage.
