Overview
The RC4WD Gear Set for Super Bully 2 Competition Axles (Z-G0081) is a premium replacement drivetrain component engineered for serious RC rock crawling enthusiasts and competition drivers across the UK. Whether you're a seasoned competitor pushing your RC crawler to its limits or a dedicated hobbyist who demands reliability in challenging terrain, this gear set delivers the precision engineering and durability required for demanding off-road performance. RC4WD has established itself as a trusted name in the RC car UK community, known for manufacturing high-quality scale RC parts that stand up to the rigours of competitive rock crawling and extreme terrain navigation.
This is not a complete vehicle—it is a specialist component designed specifically for the Super Bully 2 Competition Axle system. If you're upgrading your existing Super Bully 2 setup or rebuilding your axle drivetrain after wear, this gear set is the genuine RC4WD solution that ensures compatibility and performance. Built using precision CNC machining and hardened steel construction, this gear set represents the quality standard you should expect from dedicated RC specialists in the UK who understand what rock crawling demands from their equipment.
The RC4WD Gear Set for Super Bully 2 Competition Axles is ideal for builders who already own the Super Bully 2 Competition Axle and need to replace worn gears or upgrade their existing setup. This component is not for beginners looking to assemble their first ready to run RC vehicle, but rather for experienced RC enthusiasts and competitive drivers who understand axle systems and drivetrain components. If you're shopping for RC parts in the UK and need a proven, manufacturer-backed gear set from a recognised brand, this product delivers exactly what the RC community expects from RC4WD.
Key Features
- CNC Machined Precision — Every tooth profile and gear surface is machined to exact tolerances using computer numerical control equipment, ensuring perfect mesh engagement with mating gears and eliminating the slop and backlash that compromises traction and control during rock crawling manoeuvres. This level of precision is essential when navigating challenging terrain where every movement must be deliberate and responsive.
- Hardened 45# Steel Construction — The gear set is manufactured from high-grade 45# steel, a material specifically chosen for its superior strength and wear resistance in demanding drivetrain applications. This steel composition provides the hardness necessary to withstand the extreme torque loads and shock impacts experienced during rock crawling without fracturing or stripping teeth.
- Heat Treatment Process — Beyond the inherent properties of 45# steel, the gear set undergoes professional heat treatment which further enhances material hardness and longevity. This metallurgical process creates a durable surface layer that resists wear, extends component lifespan, and maintains gear integrity across hundreds of climbing and crawling sessions.
- Durable Black Finish — The black coating provides more than aesthetic appeal; it offers corrosion protection against the moisture, mud, and environmental exposure that RC crawlers inevitably encounter in UK terrain such as quarries, moorlands, and purpose-built rock crawl courses. This protective finish helps maintain the gear set's structural integrity over extended use.
- Competition-Grade Engineering — This gear set is designed and manufactured to meet the demands of competitive rock crawling where reliability and performance consistency are non-negotiable. RC4WD's commitment to competition-standard engineering means these gears are built to the same exacting specifications used in race-level Super Bully 2 Competition Axle systems.
Technical Performance
The RC4WD Gear Set for Super Bully 2 Competition Axles represents serious drivetrain engineering for those who demand the best from their RC crawler. Weighing just 2.21 ounces (62.7 grams), the gear set is designed to minimise unsprung weight while maximising strength and durability. The precision CNC machining ensures that gear tooth profiles mesh flawlessly with mating components, reducing friction losses and improving power transmission efficiency throughout your drivetrain. The hardened 45# steel construction combined with heat treatment creates a material matrix capable of withstanding the extreme torque multiplication that occurs through modern low-ratio axle gearing—exactly what rock crawling demands. When you're navigating technical terrain with a crawler that weighs significantly more than a standard off-road RC car, drivetrain components must be robust enough to handle forces that would destroy lesser-quality gears. The black finish not only looks professional but also provides essential corrosion resistance in the damp UK climate. This is the kind of component that allows serious RC enthusiasts to push their crawlers harder and longer without fear of drivetrain failure. Whether you're competing in organised rock crawl events or tackling natural terrain challenges, these gears deliver the performance and longevity that the Super Bully 2 platform is designed to provide.

Frequently Asked Questions
- Is the RC4WD Gear Set for Super Bully 2 Competition Axles suitable for beginners? — No, this component is not for beginners. It is a replacement gear set designed for experienced RC builders and competition drivers who already own a Super Bully 2 Competition Axle and understand drivetrain systems. Beginners should start with a complete ready to run RC vehicle rather than individual drivetrain components. If you are new to RC rock crawling in the UK, we recommend visiting our Walsall store or contacting our team to discuss whether upgrading to a Super Bully 2 system is the right choice for your skill level.
- What is this component used for? — This is a replacement gear set designed specifically for the Super Bully 2 Competition Axle (model Z-A0122). It is used to rebuild or upgrade the internal drivetrain gearing in that axle system. If your existing gears have worn out, become damaged, or if you want to optimise your drivetrain for competition, this genuine RC4WD gear set is the correct replacement component.
- Do I need any special tools to install this gear set? — While the source information does not specify tools required, installing a gear set in a competition axle typically requires precision tools and mechanical knowledge. We recommend contacting the RC Model Shop team for installation advice before purchasing. Our experienced staff can guide you through the process or recommend a qualified builder who can handle the installation correctly.
- What makes these gears different from standard gears? — The RC4WD Gear Set for Super Bully 2 Competition Axles is manufactured to competition-grade specifications using CNC machining and hardened, heat-treated 45# steel. This precision engineering and material selection results in gears that maintain exact tolerances, mesh perfectly with axle components, and withstand the extreme stresses of rock crawling far better than standard components. Competition-grade engineering is the key difference that makes these gears worth the investment.
- What is the weight of this gear set? — The RC4WD Gear Set weighs 2.21 ounces or 62.7 grams. This relatively light weight is important for rock crawlers because it minimises unsprung weight, which helps maintain traction and ground contact over challenging terrain whilst keeping overall vehicle weight manageable.
- Why are the included pins and set screw important? — The gear set comes with two precision pins (2.5mm x 7.7mm and 2.0mm x 10.7mm) and one M3 x 3mm set screw. These fasteners are essential for properly securing gears to axle shafts and maintaining correct alignment and preload within the axle assembly. Using the correct, included fasteners ensures that your gear set performs exactly as RC4WD intended.
- Is this a genuine RC4WD product? — Yes, when you purchase from RC Model Shop, you receive an authentic RC4WD product from an authorised retailer. We stock only genuine products from the manufacturers we represent, ensuring you receive components built to the exact specifications RC4WD designed and that carry the manufacturer's quality guarantee.
