Overview
Fine-tune your RC crawler's handling with the RC Overhaul Axle Weight – Black Brass 4mm (4pcs) SCX30, part number G-RCO-AX046. Whether you're tackling technical terrain or looking to improve your vehicle's performance on challenging ground, these precision-engineered brass weights are an essential upgrade for any RC enthusiast in the UK. The black brass construction adds concentrated mass directly at the axle, helping to lower the centre of gravity and dramatically improve stability when navigating sidehills, off-camber sections and steep climbs. Supplied as a set of four pieces, this 4mm specification set offers a tidy option for weight tuning without adding unwanted bulk to your chassis.
Brass weights have become a popular choice among RC car UK enthusiasts for dialling in traction and balance, helping your vehicle stay planted exactly where you need it most. The understated black finish blends neatly with typical chassis hardware for a clean, OEM-style look that doesn't compromise on performance. These axle weights are specifically designed to work with the AX045 4mm longer driveshafts, creating a total transformation of control and ride quality. When used in combination with extended driveshafts, you'll gain an 8mm wider track and increase the corner weight by nearly 5 grams per corner, delivering a much more planted feeling and noticeably improved handling characteristics.
For anyone serious about getting the best out of their Axial SCX30 crawler, upgrading to heavier brass axle weights is a proven modification that delivers real-world improvements in performance. This is one of the most effective weight tuning modifications you can make, and it's something that competitive RC crawlers and serious hobbyists rely on to gain that extra edge when tackling difficult terrain.
Key Features
- Black Brass Construction — The brass material offers superior density and concentrated mass placement compared to lighter alternatives, allowing you to add significant weight in a compact form factor that won't upset your chassis geometry or introduce unwanted mass in the wrong places.
- 4mm Specification — Specifically sized to work with 4mm longer driveshafts and standard SCX30 axle components, ensuring perfect fitment and compatibility without requiring modification or trial and error.
- Set of Four Pieces — This pack contains four individual weights, allowing you to add 5 grams of corner weight per wheel for balanced weight distribution and improved corner-exit traction.
- Lowers Centre of Gravity — By placing weight at the axle point, these weights sit lower on the chassis, dramatically improving stability when navigating uneven terrain, rocky sections and technical climbing scenarios.
- Improved Traction and Balance — The added weight helps your crawler stay planted during cornering, climbing and side-hill traversal, giving you better control and more predictable handling characteristics.
- OEM-Style Black Finish — The understated black colour blends seamlessly with standard chassis hardware and drivetrain components, maintaining a professional appearance without the need for custom painting or cosmetic modifications.
- Proven Performance Upgrade — Designed to work in conjunction with extended driveshafts to create an 8mm wider track, these weights are a recognised modification among competitive RC crawler drivers and serious hobbyists.
Technical Performance
The RC Overhaul Axle Weight represents precision engineering at its finest. Built from high-density black brass, these weights deliver concentrated mass exactly where it matters most – at the wheel corners of your SCX30 crawler. The material choice is deliberate; brass offers superior weight-to-volume ratio compared to plastic or lighter metals, meaning you can add significant mass without creating bulky, oversized components that compromise clearance or aesthetics. Each weight adds approximately 1.25 grams per piece, allowing for precise corner-weight tuning across all four wheels. When installed as a complete set of four, you're adding nearly 5 grams of corner weight per wheel, fundamentally transforming how your crawler behaves on technical terrain. The 4mm specification is engineered to pair perfectly with the RC Overhaul AX045 4mm longer driveshafts, creating a synergistic upgrade that increases track width by 8mm whilst maintaining perfect geometry and suspension kinematics. This combination prevents the common problems associated with poorly executed weight modifications – weight sag, altered suspension angles or compromised steering geometry. The brass material won't corrode or degrade in wet conditions, making these weights equally suitable for wet weather crawling or indoor carpet courses. Installation requires only basic tools and takes minutes, making this one of the most accessible yet effective performance modifications available for the Axial SCX30 platform in the UK RC car market.

Frequently Asked Questions
- Will these axle weights improve my SCX30 crawler's handling on technical terrain? — Yes. By lowering your vehicle's centre of gravity and adding corner weight, these brass weights dramatically improve stability on sidehills, off-camber sections and technical climbs. The added mass helps keep your crawler planted on uneven ground, giving you better traction and more predictable handling characteristics.
- Can I use these weights on their own, or do I need the longer driveshafts? — Whilst these weights can be installed on their own, RC Overhaul specifically recommends pairing them with the AX045 4mm longer driveshafts for optimal results. When used together, you gain an 8mm wider track and the full performance benefit of the weight tuning modification.
- How much weight do these add to my crawler? — Each weight adds approximately 1.25 grams. When installed as a complete set of four, you're adding nearly 5 grams of corner weight per wheel, transforming your vehicle's handling without adding excessive overall mass.
- Will the black brass finish scratch or corrode? — Brass is naturally corrosion-resistant and durable. The black finish may show minor scuffs with use, but these weights are built to withstand the demands of serious RC crawling and will not degrade in wet or muddy conditions.
- Are these weights suitable for beginners? — These weights are suitable for anyone looking to upgrade their SCX30 crawler, from beginners to experienced drivers. Installation is straightforward and requires no special tools or expertise. However, they are most effective when paired with extended driveshafts for the full performance benefit.
- What is the difference between brass weights and plastic weights? — Brass offers significantly higher density than plastic, meaning brass weights provide more mass in a smaller, more compact form. This allows for more precise weight tuning without creating bulky, oversized components. Brass is also more durable and won't degrade over time with use.
- Will these weights fit my specific SCX30 model? — These weights are designed for SCX30 applications that accept 4mm axle weights. We recommend confirming your specific model's requirements and clearances before installation, as some variants may have different mounting requirements.
