Team Associated ASC21507 Rear Hubs Caster Blocks

The Team Associated ASC21507 set supplies the rear hubs, front caster blocks, and geometry inserts for the Reflex 14 platform. The caster blocks carry the front steering assembly and set caster angle, while the rear hubs locate the rear wheel bearings and set rear toe and camber.

The inserts are what make this set a tuning item as well as a repair part. Changing them alters the suspension geometry at both ends, letting you trade steering response for stability or dial in more rear grip to suit the surface you are running on.

Fitment covers the Reflex 14B, Reflex 14T, Reflex 14MT Monster Truck, Reflex 14B Ongaro, and Reflex 14B Buggy, and every piece is a direct replacement using the stock hinge pins, bearings, and hardware. Hubs and caster blocks sit right in the impact path and crack in heavy crashes, so a spare set means you can rebuild a corner quickly and return to the same setup you had before.
