Overview
The ARRMA Front Suspension Arm Set B is an essential replacement or upgrade component for your 1/16 scale ARRMA MOJAVE GROM RC car UK. Whether you're a seasoned RC enthusiast or discovering the world of remote control vehicles for the first time, maintaining your suspension system is critical to achieving optimal performance and longevity. This genuine ARRMA suspension arm set is engineered to provide the durability and precision your GROM demands, whether you're bashing in your garden, competing at your local RC club, or tackling challenging terrain.
As a trusted authorised ARRMA dealer, RC Model Shop stocks this genuine suspension component to ensure your RC car UK experiences smooth, responsive handling in all conditions. The suspension arms are the fundamental foundation of your vehicle's handling characteristics, directly affecting cornering stability, jump landing control, and overall driving feel. When your stock arms become worn, cracked, or bent from aggressive use, replacing them with an official ARRMA set like the Front Suspension Arm Set B restores your GROM to factory specifications and ensures compatibility with all other suspension components.
This suspension arm set represents excellent value for RC enthusiasts who want to maintain their vehicles at peak performance without compromise. The composite construction provides an ideal balance between strength and weight, ensuring your GROM remains competitive whether you're racing or recreational bashing.
Key Features
- Tough Composite Material Construction — The suspension arms are manufactured from durable composite material that provides increased crash resistance and exceptional longevity during the most extreme RC action. Unlike brittle plastic alternatives, composite materials flex and absorb impact energy, reducing the likelihood of catastrophic failure when you land jumps hard or clip course obstacles.
- Precision Molding Technology — Each arm is precision molded to exacting tolerances, ensuring smooth suspension operation in all driving conditions. This precision manufacturing eliminates binding and ensures consistent performance whether you're carving tight corners on a race track or powering through rough terrain at full throttle.
- Complete Front Suspension Solution — This set includes both upper and lower front suspension arms, providing a comprehensive replacement or upgrade solution that maintains the correct suspension geometry and handling characteristics your GROM was designed for.
- OEM ARRMA Quality Assurance — As official ARRMA components, these arms are manufactured to the same exacting standards as the original parts fitted to new vehicles, guaranteeing perfect fitment and compatibility with all GROM variants including the 1/16 MOJAVE GROM 223S BLX 4X4, MOJAVE GROM MEGA 380, and 1/16 ARRMA MOJAVE GROM 4x4 RTA Race Kit models.
- Ball Joint Hardware Included — The set comes complete with four replacement 5.8x7x2.5mm ball joints, ensuring you have all the hardware needed for proper installation and reliable suspension articulation.
- Ideal Replacement Parts — Perfect for restoring worn suspension components or upgrading damaged arms after crashes, this set restores your GROM's suspension performance and handling precision.
Technical Performance
The ARRMA Front Suspension Arm Set B represents precision engineering optimised for small-scale RC performance. The composite material selection balances the need for impact absorption with minimal weight penalty, crucial for maintaining the responsive handling characteristics expected from a 1/16 scale desert truck platform. The precision molding ensures that the suspension geometry remains accurate across the complete range of suspension articulation, from full compression during aggressive landings to full extension when tackling obstacles. The included 5.8x7x2.5mm ball joints are the critical articulation points that allow smooth pivot motion, essential for transmitting steering inputs and maintaining traction through the suspension's full range of motion. When combined with quality shock absorbers, proper spring rates, and well-maintained anti-roll bars, these suspension arms deliver consistent, predictable handling that makes your GROM fun to drive whether you're enjoying recreational RC car UK bashings or competing seriously at your local club.

Frequently Asked Questions
- Is the ARRMA Front Suspension Arm Set B compatible with my GROM model? — Yes, this suspension arm set is specifically designed for ARRMA MOJAVE GROM models. The manufacturer confirms compatibility with the 1/16 MOJAVE GROM 223S BLX 4X4 DT (available in multiple colour variants), the MOJAVE GROM MEGA 380 Brushed 4X4, and the 1/16 ARRMA MOJAVE GROM 4x4 RTA Race Kit. Always verify your exact GROM variant against the compatibility list before ordering to ensure perfect fitment.
- When should I replace my suspension arms? — Replace your suspension arms when they become visibly cracked, bent, or develop play in the ball joint connections. Even small damage to suspension arms compromises your vehicle's handling and can lead to unpredictable behaviour during jumps or cornering. If your GROM feels unstable or handles differently than before, inspect your suspension arms carefully and replace if necessary.
- Are these official ARRMA parts? — Yes, these are genuine original ARRMA parts manufactured to the same specifications as those fitted to new vehicles. Choosing OEM ARRMA components ensures perfect compatibility, optimal performance, and reliability you can depend on.
- What is the material composition? — These suspension arms are manufactured from composite material selected for its optimal balance of strength, impact resistance, and weight. Composite provides superior crash resistance compared to brittle plastic while maintaining the lightweight characteristics essential for responsive RC handling.
- Do I need to replace upper and lower arms together? — For optimal suspension performance, it's recommended to replace suspension arms in matched pairs. This set provides both upper and lower arms, ensuring your suspension geometry remains correct and your GROM handles predictably.
- What tools do I need to install these arms? — You'll need basic RC tools including hex wrenches or a multi-tool, a ball joint tool or small flathead screwdriver for removing ball joints, and potentially suspension pins depending on your GROM's design. Consult your vehicle's instruction manual for specific installation guidance.
