Overview
The Fastrax Purple Heavy Aluminium Clutch Shoe (FAST900) is a premium upgrade component designed for serious nitro RC enthusiasts in the UK who demand reliable performance on high-grip surfaces. This heavy-duty clutch shoe represents a significant step up from standard offerings, engineered specifically for models that require exceptional bite and consistent engagement characteristics. Whether you're running a competitive 1/8th scale nitro buggy or upgrading your existing RC car setup, this Fastrax component delivers the tuneability and durability that serious bashers and racers expect from a recognised manufacturer.
What sets this clutch shoe apart is its combination of premium aluminium construction with included spring options that allow you to fine-tune engagement RPM to match your specific driving style and track conditions. The purple anodised finish isn't just for looks—it indicates a hard-anodised surface that resists wear and maintains performance over extended use. For RC car enthusiasts in the UK looking to maximise their nitro engine's potential, this is an investment in reliability and adjustability that will pay dividends across multiple seasons of use.
This product is ideal for anyone who takes their RC hobby seriously, from weekend racers preparing for competition to experienced modellers who understand the importance of quality drivetrain components. The ability to swap between two different spring rates means you can adapt to varying track conditions without purchasing multiple clutch assemblies, making it a versatile choice for your RC collection.
Key Features
- Heavy Duty Aluminium Construction — The clutch shoe is manufactured from premium aluminium that has been hard-anodised for durability, ensuring it withstands the constant friction and thermal stress of nitro engine operation without premature wear or degradation.
- Purple Anodised Finish — The distinctive purple anodising provides both aesthetic appeal and practical protection, creating a harder surface layer that resists scratching and extends component lifespan during aggressive driving.
- Dual Spring Options Included — Two different spring rates (1.0mm and 1.1mm) are provided in the box, allowing you to tune engagement RPM precisely to match your engine characteristics, driving style, and track surface conditions without needing to purchase additional parts.
- Excellent Bite on High-Grip Surfaces — This clutch shoe has been specifically engineered to provide superior grip and engagement, making it the ideal choice for traction-heavy track surfaces where standard clutches may slip or chatter.
- Tunable Engagement RPM — By swapping between the included spring rates, you can adjust when the clutch engages the flywheel, optimising acceleration feel and overall drivability to suit your personal preferences and track conditions.
- Compatible with Multiple Platforms — This clutch shoe works with a range of 1/8th scale nitro RC models, including HoBao Hyper 7 variants with different engine options, making it a smart upgrade choice if you own any compatible platform.
- Professional-Grade Reliability — Built to the standards expected by competitive RC racers, this component delivers consistent performance run after run, providing the reliability you need during important events or casual bashers.
Technical Performance
The Fastrax Purple Heavy Aluminium Clutch Shoe represents the culmination of engineering expertise focused on nitro RC drivetrain performance. Machined from premium-grade aluminium and finished with hard anodising, this component delivers exceptional durability in the demanding environment of a nitro engine bay. The heavy-duty construction ensures minimal deflection under load, maintaining consistent engagement characteristics even during extended driving sessions or high-speed acceleration runs. The included 1.0mm and 1.1mm spring options provide flexibility in tuning, allowing you to optimise the clutch engagement point anywhere within a range that accommodates most popular nitro engine displacement ratings used in 1/8th scale RC buggies and trucks. The aluminium material offers an excellent strength-to-weight ratio, ensuring that adding this upgrade doesn't compromise your model's overall balance or handling characteristics. For RC enthusiasts in the UK operating nitro-powered vehicles, this clutch shoe delivers the performance consistency and tuneability that separates weekend bashers from serious competitors. The dual-spring configuration means you can adapt to changing track conditions—softer springs for loose surfaces or harder springs for packed clay—without needing to source additional components or wait for delivery.

Frequently Asked Questions
- What is a clutch shoe and why would I need to upgrade mine? — A clutch shoe is the friction component that engages your nitro engine's flywheel to transmit power to the drivetrain. Upgrading to a heavy-duty aluminium version improves bite, reduces slippage, and provides better tuneability than plastic alternatives. This means better acceleration, more consistent performance, and the ability to fine-tune engagement characteristics to match your driving style and track conditions.
- How do the two different spring rates affect performance? — The 1.0mm and 1.1mm springs control the engagement point—how many RPM the clutch grabs and transfers power to the wheels. The softer 1.0mm spring will engage at a lower RPM, giving smoother acceleration but potentially less aggressive throttle response, whilst the stiffer 1.1mm spring engages higher in the RPM range for snappier acceleration. You'll want to experiment both to find which suits your driving style and track conditions best.
- Is this suitable for racing or just casual bashing? — This clutch shoe is excellent for both applications. Its professional-grade engineering makes it popular with competitive racers who demand consistency and tuneability, but the durability and reliability also make it an outstanding choice for serious bashers who want their RC car to perform reliably across multiple sessions.
- What models is this compatible with? — This clutch shoe is designed for 1/8th scale nitro vehicles. The manufacturer confirms compatibility with HoBao Hyper 7 TQ2 variants, including models with Mac 28 Turbo engines and Hyper .21 Turbo engines. If you own a different platform, please check the specifications carefully or contact us to confirm compatibility before purchasing.
- How do I install the clutch shoe and swap between spring rates? — Installation typically involves removing your existing clutch assembly and replacing it with this upgraded component. Swapping spring rates is straightforward and takes just minutes—most clutch assemblies use a simple pin or screw retention system that allows quick spring changes. Consult your vehicle's manual for specific installation instructions.
- Why choose aluminium over plastic clutch shoes? — Aluminium offers superior durability, better heat dissipation, and maintains its shape under the thermal and mechanical stress of repeated engagement cycles. Plastic clutches can warp or degrade over time, especially on high-grip surfaces or with aggressive driving. The aluminium construction means this upgrade will outlast multiple plastic alternatives, representing better value over time.
- Will upgrading my clutch improve my lap times? — A quality clutch upgrade can improve consistency and predictability, which can translate to better lap times by reducing slip, improving throttle response, and allowing you to optimise engagement for specific track conditions. However, skill and chassis tuning remain the primary factors in performance—think of this as removing a limiting factor rather than adding raw speed.
