This is an RC-scale replacement rear lower arm set produced for the TAMIYA Hornet EVO (58742) chassis, supplied in red aluminum by JAZRIDER. The parts serve as direct-fit replacements for the original rear lower arms and are intended for hobby-level maintenance, repairs, and suspension setup work.
Material and fit: the arms are aluminum and finished in red, matching the original mounting points of the Hornet EVO (58742). They are intended to preserve factory mounting geometry while offering a metal alternative to the stock plastic arms. Confirm alignment of the pivot and hub pins during installation to ensure correct suspension travel.
Installation notes: basic RC tools such as a hex driver and pliers are sufficient for removal of the stock arms and fitting these aluminum units. Retain or reuse existing screws and hardware unless replacement parts are required. When installing, tighten fasteners to secure but avoid over-torquing to prevent stripping threads in plastic hubs or bulkheads.
Tuning role: these rear lower arms are a maintenance and setup item rather than an electronic or motor upgrade. They allow consistent rear suspension geometry for repeatable toe and camber settings, and simplify part swaps during track or field maintenance. Regular inspection of ball cup fit and pivot wear is recommended during routine checks.
