Frequently Asked Questions
- Are these front lower arms compatible with all Arrma Granite Grom models? — Yes, these Fastrax aluminium arms are confirmed compatible with the Arrma 1/18 Granite Grom Mega 380 Brushed 4x4 Monster Truck RTR across all colour variants, including the Red (C-ARA2102T2), Blue/Red (C-ARA2102T1) and Green (C-ARA2102T3) versions.
- Will upgrading to aluminium suspension arms improve my RC car's performance? — Absolutely. Aluminium arms are significantly more rigid than plastic components, which reduces suspension flex during cornering and jumping. This results in improved handling response, more predictable steering, and faster corner entry — benefits that both competitive racers and casual bashers will notice immediately.
- How much more durable are these aluminium arms compared to plastic? — Aluminium offers superior impact resistance and fatigue strength compared to plastic. While plastic arms can crack or break under stress, aluminium arms can withstand much more punishment, making them ideal for aggressive off-road driving and repeated jumps on rough terrain.
- Are these arms easy to install? — Yes, these are drop-in replacements designed specifically for your Arrma Granite Grom. They require no modification to your chassis and simply replace the standard plastic arms with no additional parts or tools beyond basic RC hex wrenches needed for standard suspension maintenance.
- What is the difference between these and the factory plastic arms? — The primary difference is material and rigidity. Factory plastic arms flex during driving, compromising handling and eventually breaking under stress. These Fastrax aluminium arms eliminate flex, improve handling precision and last significantly longer, making them a worthwhile upgrade investment.
- Is this a good first upgrade for my Arrma Granite Grom? — Yes, suspension upgrades are among the most effective first modifications for any RC car. Upgrading to aluminium arms will immediately improve how your vehicle handles and reduces the risk of breakage during everyday bashing, making it an excellent choice for RC enthusiasts of all experience levels.
