As a dedicated option part for the Tamiya TT01 platform, this aluminium rear upper arm is engineered to exact specifications, ensuring perfect fitment and optimal suspension geometry.

The TT01 chassis remains one of the most popular touring car platforms in the world, and Fastrax provides the upgrade components that serious drivers rely upon.
Key Features
- Premium Aluminium Construction — Manufactured from high-quality aluminium alloy, this rear upper arm provides exceptional strength-to-weight ratio compared to plastic alternatives, ensuring your RC car UK suspension performs reliably during competitive racing and regular bashing sessions.
- Tamiya TT01 Specific Design — Engineered to precise tolerances for the Tamiya TT01 chassis platform, this component ensures perfect fitment and maintains correct suspension geometry for optimal handling and performance across all driving conditions.
- Rear Upper Arm Specification — This is a rear upper arm component (not front), making it essential for drivers who have damaged or worn the rear suspension on their TT01 and need reliable replacement parts to get back on the track quickly.
- PR Configuration — The PR designation indicates this is the passenger-side (right side) rear upper arm, allowing drivers to selectively upgrade or repair individual suspension components as needed rather than purchasing complete sets.
- Enhanced Durability — Aluminium components resist stress cracking and permanent deformation far better than plastic parts, meaning your suspension maintains geometry stability even during aggressive cornering and high-speed runs typical of competitive touring car racing.
- Improved Handling Precision — Upgrading to an aluminium rear upper arm eliminates flex and compliance in the rear suspension, translating to more predictable handling and better feedback through the steering wheel for serious RC drivers.
- Genuine Fastrax Quality — Fastrax is an authorised manufacturer of premium RC option parts, ensuring this component meets the exacting standards demanded by competitive racers and serious RC car enthusiasts across the UK and internationally.
Technical Performance
The Fastrax Tamiya TT01 Aluminium Rear Upper Arm represents a significant performance upgrade in suspension engineering for the TT01 touring car platform. By replacing the standard plastic rear upper arm with this premium aluminium component, drivers benefit from substantially improved structural rigidity, which directly translates to more consistent handling characteristics and reduced suspension compliance during cornering. The aluminium material used in this component's construction provides superior strength without adding unnecessary weight, maintaining the lightweight characteristics essential for competitive touring car racing. The precision engineering ensures that this rear upper arm integrates seamlessly with the TT01's existing suspension geometry, maintaining proper camber and toe angles that are critical for optimised tyre contact and consistent lap times. For drivers who regularly compete in touring car racing events or who bash their RC cars intensively, aluminium suspension components like this rear upper arm significantly extend overall chassis lifespan by reducing wear-related failures. The component's rigidity also reduces the tendency for suspension geometry to shift under load, meaning your setup remains consistent throughout a racing session rather than gradually becoming less responsive as plastic components flex and deform under stress.

Frequently Asked Questions
- What is a rear upper arm and why would I need to upgrade to aluminium? — The rear upper arm is a critical suspension component that connects the rear wheel hub carrier to the chassis, controlling suspension travel and maintaining wheel geometry. Upgrading to aluminium from plastic provides superior durability, eliminates suspension flex under braking and cornering, and maintains consistent geometry throughout your racing session, which is why serious RC car enthusiasts choose aluminium option parts.
- Is this suitable for beginners? — This is an option part designed for drivers who already own a Tamiya TT01 and need to replace or upgrade a specific suspension component. Beginners should first acquire a complete TT01 ready-to-run RC car; this part is then valuable when you're ready to enhance your setup or repair damage.
- Will this part fit my Tamiya TT01? — Yes, this Fastrax component is engineered specifically for Tamiya TT01 chassis platforms. The TT01 remains one of the most popular touring car platforms worldwide, and Fastrax manufactures this rear upper arm to exact OEM specifications ensuring perfect fitment.
- How do I know if I need a new rear upper arm? — You'll need to replace your rear upper arm if you notice cracks in the plastic component, significant flex during cornering, inconsistent handling behaviour, or if you simply want to upgrade for improved suspension performance and reliability during competitive racing.
- Is the PR configuration the same as the PL? — No, PR indicates the passenger-side (right side) rear upper arm, while PL indicates the driver-side (left side). Make sure you order the correct side for your vehicle, as these components are not interchangeable between left and right sides.
- What other Tamiya TT01 option parts would complement this upgrade? — For a comprehensive suspension upgrade on your RC car UK setup, consider pairing this rear upper arm with matching aluminium front upper arms, lower arms, and uprights to create a fully upgraded suspension system that delivers consistent handling and durability.
