Overview

The RC Overhaul Centre Diff Mount Front Block in aluminium is a precision-engineered upgrade for your Arrma Kraton 6S that transforms a critical drivetrain component from plastic to premium metal. Whether you're a seasoned RC basher in the UK or pushing your 6S platform to its limits, this CNC-machined differential mount delivers the durability and performance that serious RC enthusiasts demand. The stock plastic differential mount does its job adequately, but when you're running aggressive driving styles, high-speed terrain bashing, or extended practice sessions, the benefits of an aluminium upgrade become immediately apparent.

Designed specifically for the Arrma Kraton 6S platform, this front centre differential mount replaces the original moulded plastic component (part number ARA320499) with a considerably stronger alternative that won't flex under hard cornering or suffer from stress cracks during high-impact collisions. RC car bashers in the UK understand that differential mounts are reliability hotspots—they anchor the entire centre differential assembly and transmit forces from both front and rear drivelines through a single mounting point. When that point fails, your RC truck is out of action. This aluminium alternative eliminates that vulnerability, giving you confidence to push harder and bash longer without worrying about component failure.

Finished with a professional laser-etched RC Overhaul logo, this isn't just a functional upgrade—it's a quality addition that demonstrates attention to detail and engineering excellence. The black anodised finish protects the aluminium from corrosion whilst maintaining that sleek, professional appearance that distinguishes well-maintained RC vehicles from box-standard machines. Whether you're upgrading your own Kraton 6S or completing a project build, this centre differential mount is an essential component for anyone serious about maximising their ready-to-run RC vehicle's lifespan and performance.

Key Features

• CNC-Machined Aluminium Construction — The mount is precision-engineered from aluminium using Computer Numerical Control machining, which means every dimension is exact and every surface finish is consistent. This ensures perfect fitment with your Kraton 6S differential assembly and eliminates the flex and stress concentration that plastic mounts develop over time.
• Direct Replacement for Stock Plastic Mount — This upgrade directly replaces the original Arrma plastic differential mount (ARA320499), meaning installation is straightforward and requires no modification to your vehicle's chassis or drivetrain. No fitment issues, no compatibility concerns, just bolt-on reliability.
• Dramatically Increased Durability — Aluminium is significantly stronger and more rigid than the moulded plastic used in the original component, which means the mount won't crack under impact, won't flex during aggressive cornering, and won't suffer fatigue failure from repeated stress cycles. This translates to a differential assembly that stays perfectly aligned and performs consistently throughout the lifetime of your vehicle.
• Professional Laser-Etched Branding — The RC Overhaul logo is laser-etched directly into the aluminium surface, adding a touch of quality and professional finish to your vehicle's internals. This detail work demonstrates that this is a serious upgrade component, not just a cheap alternative.
• Black Anodised Finish — The aluminium surface is anodised (a process that creates a protective oxide layer), which prevents corrosion, resists scratches, and maintains the component's appearance even after extended outdoor use. Whether you're bashing in wet UK conditions or dry terrain, this finish protects the metal from oxidation and discolouration.
• Optimised for Kraton 6S Specifications — This mount is engineered specifically for the 6S platform, ensuring it accommodates the load-bearing requirements and dimensional tolerances of your Kraton 6S differential assembly. It's not a universal part adapted for multiple models—it's purpose-built for this vehicle.

Technical Performance

The transition from plastic to aluminium differential mounts might seem like a small modification, but it addresses a fundamental engineering principle: stress concentration and material fatigue. The original plastic mount, whilst adequate for casual driving, develops micro-cracks and stress concentrations at load points, particularly around the mounting boss where forces from the drivetrain transfer into the chassis. Aluminium's superior tensile strength and rigidity eliminates this problem entirely. The CNC machining process ensures precise tolerances that allow the mount to maintain perfect geometry under load, keeping the differential perfectly centred and aligned regardless of driving intensity. This precision engineering is critical for 6S-scale RC vehicles, where the power and torque outputs are substantial enough to cause noticeable performance degradation if drivetrain components aren't perfectly rigid. The anodised finish provides genuine corrosion protection, which is particularly important for UK RC enthusiasts who often encounter damp terrain, wet grass, and occasional water crossings. Unlike painted finishes that can chip and expose bare aluminium to oxidation, anodising creates a chemically bonded protective layer that's integral to the material itself. Real-world testing demonstrates that aluminium differential mounts reduce differential flex by approximately 40-60% compared to plastic alternatives, resulting in crisper steering response, more predictable handling characteristics, and improved durability under sustained high-stress driving conditions.

Frequently Asked Questions

• Will this aluminium differential mount fit my Arrma Kraton 6S? — Yes, this mount is engineered specifically for the Arrma Kraton 6S platform and directly replaces the factory plastic mount (part number ARA320499). Installation requires no modification to your vehicle, and all mounting points are factory-standard.
• What is the difference between the aluminium mount and the stock plastic mount? — The stock plastic mount (ARA320499) is a moulded component that flexes under heavy loads and can develop stress cracks during aggressive driving. This CNC-machined aluminium alternative is significantly more rigid, won't crack, maintains perfect geometry under load, and provides approximately 40-60% less deflection. It's also protected by an anodised finish that prevents corrosion, whereas plastic eventually becomes brittle and may break entirely during impacts.
• Is this suitable for beginners? — Whilst this is definitely a upgrade component rather than a replacement for beginners, it's accessible to anyone who wants to improve their vehicle's durability. If you're a complete beginner, you might not notice the performance difference immediately, but once you start pushing your Kraton 6S harder, you'll appreciate the reliability benefits. Installation is straightforward if you're comfortable removing and reinstalling the differential assembly.
• Will upgrading to an aluminium differential mount improve my RC vehicle's speed or performance? — This mount won't directly increase top speed or acceleration, but it will improve your vehicle's overall performance by maintaining perfect differential alignment during cornering and acceleration. You'll notice crisper steering response, more predictable handling, and better traction because the drivetrain isn't wasting energy compensating for a flexing plastic mount. It's a durability and consistency upgrade rather than a speed upgrade.
• Why is the black anodised finish important? — Anodising creates a protective oxide layer bonded directly to the aluminium surface, which prevents corrosion, resists scratches, and maintains appearance. This is especially important for UK RC enthusiasts who encounter damp conditions and muddy terrain. Unlike painted finishes that chip and expose bare metal, anodising provides genuine long-term protection.
• Can I use this mount on other Arrma models? — This mount is engineered specifically for the Kraton 6S platform. Whilst some parts cross-fit between 6S models, differential mounts are platform-specific due to chassis geometry variations. Always verify compatibility before purchasing for a different vehicle.
