Technical Performance
The Fastrax ARRMA Grom/Granite Aluminium Front Lower Arms represent a significant engineering upgrade from standard plastic suspension components found on many entry-level and intermediate RC vehicles. Constructed from premium grade aluminium alloy, these arms deliver measurably superior performance in terms of rigidity, impact resistance and longevity. The aluminium material has been selected for its optimal balance between weight and strength, ensuring that your 1/18 scale ARRMA Granite Grom maintains responsive handling characteristics whilst enjoying substantially improved durability under demanding driving conditions. The precision engineering of these components ensures they maintain their geometric integrity through countless impacts, jumps and aggressive cornering sequences, whereas plastic alternatives may flex, crack or break under similar stress. For RC enthusiasts across the UK who drive their vehicles regularly or competitively, this upgrade provides excellent value by reducing the frequency of suspension repairs and replacements, ultimately lowering the total cost of ownership. The arms are designed with exacting tolerances to ensure perfect fitment with the ARRMA Granite Grom platform, maintaining factory alignment specifications and suspension geometry for optimal handling and tyre wear characteristics.
