The MX0606FR set replaces the standard plastic wheel hubs on 1/4-scale Losi Promoto-MX models with machined Aluminum 7075 pattern buckles intended for improved durability at the model level. These buckles clamp to the rim pattern and limit spoke movement under repetitive impacts and load cycles encountered in off-road use.
The kit is supplied as a matched front and rear pair including the specified fasteners so installation is straightforward without extra hardware. Correct alignment to the rim pattern and incremental, balanced screw torque are key to avoiding wheel distortion during fitting.
In operation the buckles serve a tuning function by stabilising spoke geometry and helping wheels retain trueness after aggressive sessions, which improves tyre seating consistency and handling repeatability.

For precision-focused hobbyists seeking reduced wheel deformation and repeatable spoke alignment, the Aluminum 7075 MX0606FR buckle set offers a direct-fit upgrade for the listed Promoto-MX kits and lowers wheel maintenance needs between sessions.
