• Pair Format — Supplied as a matched pair, ensuring balanced suspension geometry across both sides of your vehicle, which is essential for predictable handling and professional-level driving performance whether racing or bashing.
• ARRMA-Specific Compatibility — Engineered specifically for ARRMA Kraton, Senton, and Typhon models, guaranteeing perfect fitment and eliminating any guesswork about compatibility with your RC car UK setup.
• Transmission Upgrade — Classified as a transmission tune-up component, these adaptors form part of a comprehensive drivetrain and suspension optimisation strategy, allowing you to fine-tune how power is delivered to your wheels and how your vehicle responds to terrain.
• Professional Tuning Solution — Perfect for drivers who understand suspension geometry and wish to experiment with different setups to find their optimal competitive or recreational driving configuration.

Technical Performance

These Fastrax hex adaptors represent a precision engineering solution for ARRMA 1/8 scale enthusiasts seeking suspension geometry refinement. The aluminium construction delivers the rigidity required for consistent performance during high-speed running whilst maintaining a weight-conscious design philosophy. The 13mm extension offset sits perfectly within the sweet spot for ARRMA vehicles—substantial enough to make meaningful geometry changes yet conservative enough to maintain your vehicle's fundamental balance and handling characteristics. Used as part of a broader tuning strategy alongside ride height adjustments, anti-roll bar selections, and suspension stiffness tuning, these adaptors enable you to dial in your brushless RC vehicle for specific track conditions or personal driving preferences. Whether you're running a brushless motor on 3S LiPo or pushing harder with higher voltage setups, optimising your suspension geometry through hex offset tuning ensures consistent tracking, reduced tyre wear, and improved power delivery characteristics through corners and rough terrain.

Frequently Asked Questions

• What exactly do hex offset adaptors do on an RC car? — Hex adaptors (also called hex extensions or offset adaptors) change the distance between your vehicle's suspension arm and the wheel hub. By extending the hex by 13mm, you widen your track width and adjust your suspension geometry, which affects how your vehicle sits, how its weight is distributed during cornering, and ultimately how it handles over different terrain. This is a critical tuning element for competitive RC drivers and serious enthusiasts.
• Are these suitable for beginners to RC cars? — These adaptors are intermediate-to-advanced tuning components best suited to drivers who already understand their vehicle and want to experiment with suspension setup. Beginners should focus on mastering their ARRMA Kraton, Senton, or Typhon as delivered before considering geometry modifications. However, if a more experienced friend recommends a setup adjustment using these adaptors, they're straightforward to install.
• Will these fit my ARRMA brushless RC vehicle? — These adaptors are specifically designed for ARRMA Kraton, Senton, and Typhon models. Before purchase, verify your exact vehicle model to ensure compatibility. If you own a different ARRMA model, consult the manufacturer specifications or contact RC Model Shop for confirmation.
• What's included with the pair, and how many do I need? — You receive one pair (two adaptors) with this purchase. Typically, you'll want to upgrade both front and rear suspension, which would require two pairs—one for the front hex hubs and one for the rear. Many drivers find starting with just the rear pair helpful for initial geometry testing.
• How do I install these hex adaptors on my RC vehicle? — Installation requires removing your existing hex adaptors (or hexes) from your suspension arms, sliding on the new Fastrax aluminium 13mm extension adaptors, and reinstalling your suspension arms onto the wheel hubs. This is a straightforward job requiring basic RC tools but is best performed by someone with some RC maintenance experience. Detailed assembly guides are available from ARRMA's official resources.
• Do these work with brushless motors and high-voltage LiPo setups? — Yes, absolutely. These aluminium hex adaptors function independently of your motor type, ESC, or battery configuration. They're a pure mechanical suspension component that works with any ARRMA Kraton, Senton, or Typhon drivetrain setup, whether you're running modest 3S LiPo power or aggressive brushless setups with higher voltage batteries.
