Overview
The ARRMA Wide Arm BOOST Box (G-ARA230008) is a suspension upgrade package designed to enhance the stability and handling characteristics of ARRMA GRANITE and VORTEKS RC bashers. Whether you're a beginner exploring ready to run RC cars in the UK or an experienced enthusiast looking to extract more performance from your existing vehicle, this upgrade package offers an affordable path to improved performance without the cost of purchasing a completely new RC monster truck or stadium truck. The wide arm upgrade is particularly effective for improving cornering stability, making your ARRMA basher feel more planted and responsive during aggressive driving across various terrains.
This is an official ARRMA suspension upgrade kit that transforms the handling characteristics of 4X2 BOOST, 4X4 MEGA, and 3S brushless RC vehicles by widening the track width. The package includes pre-assembled A-arms for both front and rear suspension, precision-engineered 48mm link turnbuckles, and everything you need for a straightforward installation. ARRMA has engineered this upgrade to work seamlessly with their existing BOOST platform, maintaining the same quality and reliability that has made ARRMA one of the most trusted RC brands in the UK and worldwide.
For those serious about taking their ARRMA GRANITE or VORTEKS vehicle to the next level, this Wide Arm BOOST Box represents excellent value compared to purchasing a new complete vehicle. The upgrade saves money whilst delivering tangible improvements to stability, especially during cornering and high-speed runs on dirt, grass, or hard-packed surfaces. The assembly process is straightforward, with ARRMA providing a QR code that links directly to a step-by-step video guide, making installation accessible even for users with limited mechanical experience.
Key Features
- Wider Track for Improved Stability — The extended A-arms increase the overall track width of your ARRMA basher, creating a wider stance that dramatically improves stability during cornering and high-speed manoeuvres. This wider platform means your RC vehicle experiences less body roll and maintains better traction through turns, delivering noticeably more planted and confident handling characteristics that make a real difference when pushing your basher to its limits.
- Compatible with Multiple ARRMA Platforms — This upgrade works with ARRMA GRANITE 4X2 BOOST, VORTEKS 4X2 BOOST, GRANITE 4X4 MEGA, VORTEKS 4X4 MEGA, and their 3S brushless equivalents, making it a versatile upgrade option across a wide range of ARRMA vehicles. Whether you own a monster truck or stadium truck, this package provides the suspension geometry improvements your vehicle needs for enhanced performance.
- Pre-Assembled A-Arm Components — The package includes four fully assembled A-arms (front left, front right, rear left, and rear right), eliminating the need for individual component assembly and ensuring consistent quality throughout. Pre-assembly means faster installation and guaranteed proper construction, which is especially valuable for users who want to upgrade quickly without complex mechanical work.
- Precision 48mm Link Turnbuckles — Six high-quality 48mm link turnbuckles are included to fine-tune suspension geometry and ensure proper alignment after installation. These adjustable components allow experienced users to dial in perfect suspension geometry for their specific driving style and terrain, whilst remaining straightforward enough for beginners to install without specialised knowledge.
- Video Installation Guide with QR Code — ARRMA includes a QR code that links directly to a comprehensive step-by-step assembly video, removing the guesswork from the upgrade process. This modern approach to documentation means you can watch real installation on your phone or tablet, seeing exactly how each component fits together before you start working on your own vehicle.
- ARRMA BOOST Decal Sheet Included — The package includes an authentic ARRMA BOOST decal sheet, allowing you to customise the appearance of your upgraded vehicle and maintain that aggressive ARRMA aesthetic. These official decals add visual flair whilst identifying your vehicle as part of the BOOST upgrade family.
- Significant Cost Savings vs New Vehicle Purchase — Upgrading your existing ARRMA basher with this suspension kit costs substantially less than purchasing an entirely new vehicle with factory-wide-arm geometry, making this the smart choice for budget-conscious bashers who want improved performance without breaking the bank.
- Easy Installation Process — ARRMA's modular chassis design means suspension upgrades integrate seamlessly with minimal tools required and straightforward step-by-step procedures. The upgrade doesn't require disassembly of critical components, and the intuitive design ensures that even relatively inexperienced RC enthusiasts can complete the installation in an afternoon.
Technical Performance
The ARRMA Wide Arm BOOST Box addresses one of the fundamental principles of RC vehicle dynamics: wider track width dramatically improves stability during cornering. By extending the suspension A-arms, the upgrade increases the distance between left and right wheels, reducing the vehicle's tendency to roll during aggressive turns and high-speed manoeuvres. This geometric improvement works with ARRMA's proven double-wishbone suspension system (front and rear) to deliver noticeably better handling across all BOOST-compatible vehicles. The package maintains compatibility with ARRMA's modular chassis design, which means you can remove the suspension modules quickly for maintenance without losing the benefits of the wide-arm upgrade. The 48mm link turnbuckles provide adjustment capability for fine-tuning suspension geometry, allowing experienced drivers to optimise ride height, camber, and toe-in for specific racing conditions. Whether you're using a brushed 550 MEGA motor setup on a 4X2 BOOST vehicle or have upgraded to a 3S brushless power system, this suspension upgrade works in harmony with your existing drivetrain without requiring any additional modifications. The wider stance also improves traction characteristics on uneven terrain by keeping more of the chassis flat and level during obstacle navigation, which is particularly valuable when bashing across dirt, grass, or mixed-surface environments. Installation onto ARRMA GRANITE and VORTEKS vehicles requires no special tools beyond a standard RC toolkit, and the straightforward design means you can remove and reinstall components as needed for maintenance or further customisation.

Frequently Asked Questions
- What ARRMA vehicles is the Wide Arm BOOST Box compatible with? — This upgrade kit works with ARRMA GRANITE 4X2 BOOST, VORTEKS 4X2 BOOST, GRANITE 4X4 MEGA, VORTEKS 4X4 MEGA, and their 3S brushless variants. If you own any of these ARRMA bashers in their BOOST generation or later, this suspension upgrade will fit and significantly improve your vehicle's handling characteristics.
- How much does the Wide Arm BOOST Box improve handling? — The wider track geometry noticeably improves stability during cornering and high-speed manoeuvres, particularly visible when driving aggressively through turns. Users report improved planted feel, reduced body roll, and better overall confidence when pushing their vehicles to their limits, especially on technical terrain.
- Is the installation difficult for a beginner? — No, the installation process is straightforward enough for beginners. ARRMA includes a QR code linking to a step-by-step video guide that walks you through the entire process. The modular chassis design means you don't need to disassemble critical components, and the whole upgrade typically takes an afternoon with basic RC tools.
- Can I install this upgrade myself without professional help? — Yes, the Wide Arm BOOST Box is specifically designed for user installation. The video guide removes most of the guesswork, and ARRMA's modular design philosophy means everything fits together logically. You'll need basic RC tools (hex drivers, possibly a small wrench for the turnbuckles), but no specialised knowledge or equipment.
- Do I need any additional parts to complete this upgrade? — No, the Wide Arm BOOST Box is a complete suspension upgrade package. All necessary components, fasteners, and adjustment pieces are included. You simply install it onto your existing ARRMA GRANITE or VORTEKS vehicle using tools you likely already have.
- Will this upgrade work if I've already customised my vehicle? — Yes, the Wide Arm BOOST Box is designed to integrate with ARRMA's modular platform. Whether you've upgraded your motor, ESC, or other components, this suspension upgrade installs independently and doesn't conflict with other modifications. It works equally well with stock vehicles or fully customised builds.
- What's the difference between the 4X2 BOOST and 4X4 MEGA versions of ARRMA vehicles? — The 4X2 BOOST vehicles come with 2-wheel drive and can be upgraded to 4-wheel drive using a transmission upgrade kit. The 4X4 MEGA vehicles come with 4-wheel drive from the factory. The Wide Arm BOOST Box works with all these variants, improving suspension geometry regardless of drivetrain configuration.
- Does this upgrade affect the vehicle's top speed? — This is a suspension-only upgrade that doesn't modify the motor, ESC, or drivetrain. It improves handling and stability but doesn't directly increase top speed. However, by improving cornering stability, you may be able to maintain higher speeds through turns more safely.
- Is this a genuine ARRMA product? — Yes, the Wide Arm BOOST Box is an official ARRMA option part manufactured to ARRMA's quality standards. The model number G-ARA230008 identifies it as a genuine ARRMA upgrade kit, not an aftermarket third-party component.
