AS91609

Overview

The Associated Factory Team Clamping Wheel Hex 5.0mm Offset (AS91609) is a precision-engineered wheel mounting solution designed for serious RC enthusiasts and competitive racers in the UK who demand the best performance from their vehicles. These factory-quality hexes represent the gold standard in wheel attachment technology, offering the perfect balance between durability, precision fit, and performance optimisation. Whether you're running an RC buggy, short course truck, or any of the numerous Associated models listed below, these clamping wheel hexes deliver the reliability and consistency that competitive RC racing demands.

Manufactured by Associated Electrics, a recognised leader in the RC industry, these 5.0mm clamping hexes are supplied as a pair and are built to the exacting standards that professional racers and manufacturers expect. If you're serious about RC car UK performance and want to upgrade your setup with genuine Factory Team components, this is an essential upgrade that will improve your vehicle's handling characteristics and wheel security. These hexes are particularly popular amongst UK RC competitors who appreciate the precision engineering and proven track record that comes with Factory Team products.

The primary benefit of upgrading to these clamping wheel hexes is the reduction of your vehicle's overall width by 4mm from stock dimensions, which can significantly affect handling characteristics, cornering speed, and overall stability during high-speed runs or competitive racing sessions. This width reduction is achieved through the use of a dedicated HD rear axle, creating a more compact and responsive RC vehicle setup that many competitive drivers prefer.

Key Features

• 5.0mm Clamping Wheel Hex Design — The 5.0mm offset specification provides the optimal balance between wheel security and ease of installation, ensuring your wheels remain perfectly centred and securely attached during aggressive driving, jumps, and high-speed cornering without risk of loosening or slipping.
• Supplied as a Pair — You receive two complete clamping wheel hexes in this package, providing the front and rear wheel mounting solution for your RC vehicle with guaranteed matching specifications and quality control.

• Universal Associated Compatibility — These hexes are compatible with an extensive range of Associated RC vehicles spanning multiple generations and model lines, making them a versatile upgrade option for virtually any serious Associated RC enthusiast's collection.
• Recommended Pairing with AS91608 — For optimal performance and geometry, Associated recommends using these clamping hexes with the Factory Team Aluminium Arm Mount (+4mm, C, B variant), which complements the width reduction and creates a perfectly matched suspension geometry.

Technical Performance

The Associated Factory Team Clamping Wheel Hex 5.0mm Offset represents the pinnacle of wheel mounting technology in the RC hobby. Engineered with precision tolerances that are typical of genuine Factory Team components, these hexes feature a robust 5.0mm clamping specification that provides secure wheel mounting whilst remaining easy to install and adjust. The design philosophy behind these components reflects decades of racing experience and real-world track testing, ensuring that every dimension and feature serves a specific performance purpose. By reducing your vehicle's width by 4mm from stock, these hexes effectively lower your centre of gravity and improve weight distribution, which translates to faster cornering speeds and more predictable handling characteristics. The requirement for an HD rear axle (part number 71019, which comes standard on B5M Factory Lite, T5M, and RC10SC5M models) ensures that your drivetrain has the mechanical strength to handle the demands of competitive racing. The precision clamping mechanism prevents wheel wobble or movement, which is critical for maintaining consistent suspension geometry during dynamic driving. Materials used in the manufacture of these components are selected for their strength-to-weight ratio, ensuring durability without adding unnecessary mass to your RC vehicle. For UK RC racers who compete in BRCA events or other competitive venues, upgrading to genuine Factory Team components like these hexes often makes the difference between winning and losing, as every fraction of a second and every handling improvement counts in close competition.

Frequently Asked Questions

• Are these clamping wheel hexes suitable for beginners? — Whilst these are professional-grade Factory Team components designed primarily for competitive racing and experienced RC enthusiasts, beginners can certainly use them if they have a compatible Associated vehicle. However, beginners should ensure they have the necessary HD rear axle and understand that these are upgrade components rather than essential items for casual recreational driving.
• Will these clamping hexes fit my Associated RC car? — These hexes are compatible with an extensive range of Associated models spanning multiple generations. The compatibility list includes over 40 different models and variants, from the modern RC10B7 series through to classic vintage models. If your Associated vehicle appears in the compatibility list provided, these hexes will fit perfectly. If you're unsure whether your specific model is compatible, we recommend contacting our expert team at RC Model Shop before purchasing.
• What is the main benefit of upgrading to 5.0mm clamping wheel hexes? — The primary benefits include a 4mm reduction in overall vehicle width compared to stock setups, which improves cornering response and handling precision, plus the secure clamping mechanism ensures your wheels remain perfectly centred and won't loosen during aggressive driving or racing. The geometry change also improves weight distribution and can result in measurable performance gains in competitive racing situations.
• Do I need an HD rear axle to use these hexes? — Yes, these clamping wheel hexes require an HD (heavy-duty) rear axle for proper fitment and optimal performance. The good news is that the HD rear axle (part number 71019) comes standard on the B5M Factory Lite, T5M, and RC10SC5M models. If you're retrofitting these hexes to other Associated models, you'll need to source the HD rear axle separately, though it's a commonly available and reasonably priced component.
• What is the difference between 5.0mm clamping hexes and standard hexes? — The 5.0mm specification refers to the offset dimension and clamping mechanism design. These Factory Team hexes feature precision engineering and tighter tolerances than basic alternatives, which results in more secure wheel mounting, better handling consistency, and improved performance during competitive racing. The clamping design itself provides superior wheel security compared to simple screw-in alternatives.
• Can I use these hexes with the stock geometry setup on my Associated vehicle? — These hexes are specifically designed to reduce vehicle width by 4mm, which means they alter your vehicle's geometry compared to stock. For optimal handling and suspension geometry, Associated recommends pairing them with the Factory Team Aluminium Arm Mount (+4mm, C, B), which complements the width reduction and ensures your suspension geometry remains balanced and optimised.
• Are these genuine Factory Team components? — Yes, these are genuine Associated Factory Team components manufactured to the exact specifications used by Associated's professional racing teams.
