Compatible with the Arrma Mojave Grom 1/18, this suspension upgrade is ideal for drivers who want to minimise downtime from broken parts and maximise their driving enjoyment. The machined finish and robust construction mean these arms will withstand hard impacts, high-speed runs, and challenging off-road conditions that would damage lesser quality components. Whether you're bashing around your garden, competing in local RC events, or simply want a more durable setup that requires fewer repairs, the VITAVON CNC Alu7075 Rear Upper/Lower Arm is an investment in reliability and performance that pays dividends every time you take your RC car out.
Key Features
- CNC Machined Construction — Each arm is precision-engineered using Computer Numerical Control machinery, ensuring perfect tolerances and consistency that would be impossible to achieve by hand. This manufacturing process guarantees that both arms are absolutely identical, which means perfectly balanced suspension geometry and predictable handling every single time you drive.
- Aerospace-Grade Aluminium 7075 Material — These arms are crafted from high-quality aluminium 7075, one of the strongest aluminium alloys available in the RC industry. This material offers superior strength and durability compared to standard plastic components, meaning they will withstand impacts, jumps, and aggressive driving without cracking, bending, or breaking as easily as cheaper alternatives.
- Significantly Stronger and More Durable — The combination of premium material and precision manufacturing creates arms that are noticeably stronger and longer-lasting than original equipment manufacturer parts. This durability directly translates to reduced repair costs and downtime, allowing you to spend more time driving and less time fixing your RC vehicle.
- Perfect Fit for Arrma Mojave Grom 1/18 — These arms are specifically engineered to fit the Arrma Mojave Grom 1/18 scale buggy with absolute precision, using the original part number ARA330840 as the reference. This ensures perfect fitment without modification, shimming, or adjustment when replacing worn or damaged original arms.
- Professional Silver Finish — The attractive silver anodised finish provides excellent protection against corrosion whilst maintaining a professional, refined appearance. This finish is more durable than painted alternatives and resists UV fading, ensuring your RC car continues to look as good as it performs.
- Rear Upper and Lower Arm Set — This product includes both the upper and lower rear suspension arms in one package, making it convenient to upgrade both components at once for balanced suspension performance. Replacing both arms together ensures symmetrical geometry and optimal handling characteristics.
Technical Performance
The VITAVON CNC Alu7075 Rear Upper/Lower Arm represents a quantum leap in suspension component quality for 1/18 scale RC buggy drivers. Constructed from premium aluminium 7075, these arms deliver exceptional rigidity and impact resistance that genuinely transforms how your Arrma Mojave Grom handles demanding driving conditions. The material science behind aluminium 7075 is well-established in aerospace and professional engineering applications, and VITAVON's decision to use this specification for RC components demonstrates their commitment to quality that exceeds typical hobby-grade standards. The precision CNC machining process ensures that every arm meets exact dimensional specifications, eliminating the manufacturing tolerances and inconsistencies that plague lower-quality aftermarket parts. This precision engineering is absolutely critical in suspension geometry because even tiny variations can affect handling balance, tyre wear, and overall performance. The stronger material composition of these arms means they absorb impacts more effectively than plastic alternatives, protecting your differential and chassis from secondary damage when your RC car hits obstacles or lands hard from jumps. For drivers who frequently bash their RC cars, upgrade to these arms quickly becomes a sensible investment that prevents cascading damage from broken suspension components. The superior durability of aluminium also means these arms will maintain their strength through hundreds of driving sessions without developing the micro-cracks that eventually appear in plastic components under stress. Whether you're running on dirt tracks, rocky terrain, gravel surfaces, or concrete surfaces, these arms provide the reliable foundation that keeps your Arrma Mojave Grom performing consistently.

Frequently Asked Questions
- Will these VITAVON arms fit my Arrma Mojave Grom 1/18? — Yes, absolutely. These arms are specifically manufactured for the Arrma Mojave Grom 1/18 and reference the original part number ARA330840, ensuring perfect fit and function without any modification or adjustment required. They will drop straight into your RC buggy as direct replacements for the standard components.
- Why should I upgrade from standard plastic arms to these aluminium arms? — Aluminium 7075 offers dramatically superior strength and durability compared to plastic, which means these arms are far less likely to crack or break during aggressive driving, jumps, and impacts. The precision CNC manufacturing also ensures perfect consistency between both arms, resulting in better handling balance. Over time, the reduced breakage and fewer repairs actually make these arms more cost-effective than repeatedly replacing damaged plastic components.
- Are these arms suitable for competitive racing or just casual bashing? — These VITAVON arms are suitable for both applications. The precision engineering and premium materials make them excellent for competitive drivers who need absolute reliability during races, whilst the enhanced durability also makes them ideal for weekend bashers who want to minimise downtime from broken parts. Any driver serious about their RC car UK setup will appreciate the quality on offer here.
- How do CNC machined parts compare to cast or injection-moulded alternatives? — CNC machining offers superior precision and consistency compared to casting or injection moulding, both of which can have slight imperfections and dimensional variations. This precision is particularly important in suspension geometry where even small inconsistencies affect handling. Additionally, the solid metal construction through the entire part provides better structural integrity than hollow cast components, ensuring these arms maintain their geometry under stress and impact.
- Will these arms improve the handling of my Mojave Grom? — Whilst these arms won't dramatically change your Grom's fundamental characteristics, upgrading to perfectly matched aluminium arms does improve handling consistency and responsiveness by providing better geometry stability and reducing flex in the suspension. The primary benefit is reliability and durability rather than outright performance improvement, though more responsive handling is a welcome side effect of the improved structural rigidity.
- How often will I need to replace these arms? — With proper care, aluminium 7075 arms last significantly longer than plastic alternatives. The exact replacement interval depends entirely on your driving intensity and conditions, but many drivers report getting hundreds of hours of driving before needing replacement. Even when they do eventually wear out, the superior structural integrity means they'll maintain performance longer and fail less suddenly than plastic components.
