The locker mechanism ensures maximum traction by eliminating wheel spin, giving you the control and confidence to tackle slopes and obstacles that would otherwise be impossible to overcome.
RC Model Shop stocks this highly-rated component, which has earned a 4.4 out of 5 customer rating from experienced users who trust Axial's engineering and design. Available as a replacement or optional upgrade part, the AR44 6-Bolt Differential Locker is the choice of serious RC crawler pilots across the UK who understand that differential performance directly impacts their vehicle's capability and overall trail performance.
Key Features
- Six-Bolt Design — The robust six-bolt attachment pattern provides exceptional durability and reliable engagement, ensuring the locker mechanism remains secure and functional even during the most aggressive off-road adventures on rocky terrain and technical obstacles.
- Machined Steel Construction — Premium machined steel components guarantee longevity and strength, resisting wear and damage from continuous use in harsh conditions, whilst maintaining precise tolerances that keep your RC crawler running smoothly season after season.
- Enhanced Traction Control — By locking both axle shafts together, this component eliminates the wheel slip that occurs with standard open differentials, delivering maximum grip and control when climbing steep inclines and traversing uneven ground in your 1/10 scale RC crawler.
- Complete Hardware Package — Each locker arrives with six cap head screws included, meaning you have everything needed for installation without hunting for compatible fasteners or making additional purchases.
- Broad Compatibility — Engineered to fit an extensive range of Axial SCX10 III models including the Jeep JLU Wrangler with portals, Early Ford Bronco, Jeep Gladiator, Toyota SR5, Jeep CJ-7, and all Base Camp variants, plus compatibility with Capra 1.9 unlimited models, making this a versatile upgrade for multiple RC platforms.

Technical Performance
The AR44 6-Bolt Differential Locker represents serious engineering designed specifically for the demands of 1/10 scale rock crawling. The machined steel construction provides exceptional rigidity and strength, ensuring the locker mechanism engages reliably under load without deflection or slippage. The six-bolt pattern distributes stress evenly across the engagement surfaces, preventing premature wear and maintaining consistent performance across hundreds of hours of trail time. This component directly addresses one of the most critical aspects of crawler performance: traction management. When both wheels on an axle rotate at the same speed, your RC crawler gains the mechanical advantage needed to climb steep slopes, navigate through rocky obstacles, and maintain forward momentum in situations where an open differential would leave you spinning helplessly. The precision machining ensures tight tolerances that keep the locking mechanism engaged even during extreme articulation, when suspension geometry is pushed to its limits. Installation is straightforward for anyone with basic RC maintenance experience, and the included cap head screws ensure you're not left searching for hardware. This is a genuine Axial component engineered to work flawlessly with the SCX10 III platform and compatible Capra models, delivering the performance enhancement that serious RC crawlers demand for technical courses and extreme terrain.

Frequently Asked Questions
- What is a differential locker and why do I need one for my RC crawler? — A differential locker is a mechanical component that forces both wheels on an axle to rotate at the same speed, eliminating wheel slip and maximising traction. Standard open differentials allow wheels to spin at different speeds for cornering efficiency on flat surfaces, but in off-road crawling, this causes one wheel to spin uselessly whilst the other loses grip. Locking your differential transforms your RC crawler's ability to climb steep inclines, cross rocky terrain, and maintain momentum through technical obstacles where traction is everything.
- Will this locker fit my Axial SCX10 III? — Yes, the AR44 6-Bolt Differential Locker is specifically engineered for Axial SCX10 III models. It is compatible with virtually every variant in the SCX10 III range, including the Jeep JLU Wrangler with portals, Early Ford Bronco, Jeep Gladiator, Toyota SR5, Jeep CJ-7, and all Base Camp editions. It is also compatible with Capra 1.9 unlimited models including the standard Capra, Capra 1.9 4WD Unlimited Trail Buggy Kit, and Capra 1.9 4WS models.
- What does the six-bolt design offer compared to other locker styles? — The six-bolt design provides multiple engagement points that distribute stress evenly across the locker mechanism, delivering enhanced durability and reliability during extreme use. This multi-point attachment pattern prevents the concentrated wear that can occur with fewer bolts, extending the service life of your differential and maintaining consistent locking performance across hundreds of trail hours.
- Do I need any special tools to install this locker? — Installation requires basic RC maintenance tools such as Allen keys to fit the included cap head screws. No specialised tools or advanced mechanical knowledge is required, making this upgrade accessible to RC enthusiasts with moderate mechanical experience. If you're uncertain about installation, RC Model Shop can provide guidance and support.
- Is the AR44 locker suitable for beginners? — Whilst the locker itself is a straightforward component, differential work requires some mechanical confidence. Beginners new to RC maintenance should consider having the locker installed by an experienced RC technician, or they can consult detailed installation guides and video tutorials available online. Once installed, the locker is maintenance-free and simply works to improve your crawler's performance.
- What material is this locker made from? — The AR44 6-Bolt Differential Locker is constructed from premium machined steel, which provides exceptional strength, wear resistance, and longevity. Steel's superior hardness compared to aluminium ensures the locker maintains precise tolerances and reliable engagement even after extended use in harsh terrain.
- Will fitting a locker change how my RC crawler handles? — Yes, in a positive way. Your RC crawler will experience dramatically improved traction and climbing ability, particularly on steep and technical terrain. You may notice slightly reduced manoeuvrability in tight turns on smooth surfaces due to both wheels being locked together, but this is a minor trade-off for the substantial gains in off-road crawling performance that matter most for trail and course use.
