Overview
The ARRMA Steering Set, CNC Aluminum (model ARA340173) represents the pinnacle of upgrade parts for serious RC enthusiasts in the UK who demand maximum performance and durability from their vehicles. This premium steering component is engineered specifically for ARRMA's most extreme models, including the 1/5 KRATON 4WD 8S BLX brushless speed monster truck and the 1/5 OUTCAST 4WD 8S BLX stunt truck. Whether you're a weekend basher looking to enhance your ready to run RC car or a dedicated competitor seeking competition-grade upgrades, this CNC-machined aluminium steering set delivers the precision, strength and reliability that separates champion-level builds from standard setups.
This EXtreme Bash (EXB) specification steering set combines cutting-edge engineering with premium materials to create a steering system that can withstand the most grueling action and punishment. The complete package includes an aluminium steering rack, two aluminium steering bellcranks (left and right), and four precision ball bearings that work together to eliminate steering slop and deliver crisp, responsive handling characteristics. The anodised red finish and laser-etched ARRMA logo add authentic style that matches the aggressive aesthetic of modern brushless RC monster trucks and stunt trucks.
For UK RC enthusiasts who refuse to compromise on quality, this steering upgrade represents a significant investment in the longevity and performance of your brushless RC vehicle. The combination of aerospace-grade 7075-T6 aluminium construction with CNC precision machining ensures that every component fits perfectly and performs consistently, lap after lap, bash after bash.
Key Features
- CNC Machined 7075-T6 Aluminium Construction — The entire steering set is precision-machined from high-grade 7075-T6 aluminium alloy, which is renowned in aerospace and automotive applications for its exceptional strength-to-weight ratio and resistance to fatigue, ensuring your steering system will survive the most demanding driving conditions without bending or breaking.
- EXtreme Bash (EXB) Specification — ARRMA's EXB parts are specifically engineered using extremely strong and durable materials designed to survive the most grueling action, making this steering set ideal for high-speed bashing, jumps, and aggressive off-road driving without premature wear or failure.
- Four Precision Ball Bearings Included — The set comes equipped with four ball bearings (6 x 10 x 3mm each) that provide smooth, slop-free steering action, ensuring your steering inputs translate immediately and accurately to the wheels for superior control and predictability.
- Anodised Red Finish for Style and Protection — The anodised coating provides both aesthetic appeal with authentic ARRMA red colouring and practical corrosion resistance, protecting the aluminium from oxidation and environmental damage during storage and use.
- Laser-Etched ARRMA Logo — Professional laser etching adds genuine branding and visual appeal, giving your RC monster truck or stunt truck a premium, competition-ready appearance that reflects the quality of the upgrade.
- Stiff and Strong Engineering — Unlike plastic steering components that can flex and wear, this all-aluminium construction maintains rigidity under extreme cornering forces and impact loads, preserving steering accuracy and responsiveness throughout the lifetime of your RC vehicle.
Technical Performance
This steering set represents a significant upgrade from standard plastic steering components found on basic ready to run RC models. The 7075-T6 aluminium material is one of the strongest aluminium alloys available, comparable to the materials used in racing applications and aerospace engineering. The CNC machining process ensures tolerances are held to extremely tight specifications, eliminating the fit and finish inconsistencies that can plague plastic alternatives. The four included ball bearings (each measuring 6 x 10 x 3mm) are precision components that dramatically reduce friction in the steering system, allowing for faster response times and more accurate directional control. The complete assembly—comprising the aluminium steering rack and both left and right bellcranks—is designed to work together as an integrated system that maintains perfect geometry under load, even during the most aggressive cornering and high-speed maneuuvres. For UK RC enthusiasts running 1/5-scale brushless vehicles like the KRATON or OUTCAST, the weight penalty of aluminium (compared to plastic) is negligible, whilst the durability benefits are substantial. This upgrade is particularly valuable for drivers who regularly bash at high speeds, perform aerial tricks, or run competition-level setups where steering precision and component reliability are non-negotiable. The anodised finish provides additional protection against corrosion, making this set suitable for use in damp UK conditions without degradation.

Frequently Asked Questions
- Is this steering set compatible with my ARRMA brushless monster truck? — This steering set is specifically designed for 1/5-scale ARRMA vehicles including the KRATON 4WD 8S BLX and OUTCAST 4WD 8S BLX models. Check your vehicle's manual or contact our team to confirm fitment before purchasing, as this is an optional upgrade part.
- What is the advantage of aluminium steering components over plastic? — Aluminium offers significantly superior strength, rigidity and durability compared to plastic steering parts. Whilst plastic components can flex under load, crack under impact, or wear over time, aluminium maintains its geometry and responsiveness indefinitely, making it ideal for high-speed bashing and aggressive driving where steering precision is critical.
- Will this upgrade improve my RC car's handling? — Yes, the four precision ball bearings eliminate steering slop and reduce friction, resulting in crisper, more responsive steering inputs. Combined with the rigid aluminium construction that resists flex and deformation, you'll experience noticeably improved directional accuracy and control, particularly during high-speed cornering and aggressive manoeuvres.
- Is this suitable for beginners? — Whilst this steering set is not required for basic recreational bashing, it is an excellent upgrade for beginners who want to improve their vehicle's durability and handling characteristics. Installation requires basic mechanical knowledge and appropriate tools. If you're new to RC modifications, our experienced team at RC Model Shop can provide guidance or installation support.
- Do I need any additional tools or parts to install this steering set? — Installation requirements depend on your specific ARRMA model and current steering setup. You may need basic hand tools such as screwdrivers, hex wrenches, and possibly a small press or bearing puller, depending on your model. Consult your vehicle manual or contact our team for detailed installation guidance specific to your vehicle.
- What does EXB (EXtreme Bash) specification mean? — EXB parts are specifically engineered by ARRMA using extremely strong and durable materials selected to survive the most grueling action, including high-speed bashing, jumps, and impacts. EXB specification components are designed to withstand abuse that would damage standard parts, making them ideal for aggressive drivers and competitive users.
- Why are four ball bearings included? — The four ball bearings (6 x 10 x 3mm) are installed in the steering system to provide smooth, frictionless rotation. They eliminate steering slop and ensure your steering inputs are transmitted immediately and accurately to the wheels, resulting in superior control and predictability during driving.
- Is the anodised finish just cosmetic? — Whilst the anodised red finish certainly looks professional and matches ARRMA's aggressive styling, it serves a practical purpose as well. The anodised coating provides corrosion resistance, protecting the aluminium from oxidation and environmental damage, particularly important for UK users who may store vehicles in damp conditions or use them in wet weather.
