TRX5333R

Overview

The Traxxas Suspension arm Set (TRX5333R) is an essential tune-up component for Traxxas Revo, E-Revo and Summit owners looking to optimise their RC car's performance and handling characteristics. This adjustable wheelbase suspension upgrade allows you to extend your vehicle's wheelbase by either 10mm or 19mm in just minutes, making it one of the most practical and effective modifications available for serious RC enthusiasts across the UK. Whether you're a competitive racer fine-tuning your setup or a weekend basher seeking improved stability, this suspension arm set delivers straightforward installation with trackside adjustability that genuinely makes a difference to how your RC car performs.

Designed with the philosophy that suspension geometry directly impacts traction, stability and cornering performance, the TRX5333R puts the power of wheelbase adjustment directly in your hands. The beauty of this system lies in its simplicity: by repositioning the pivot ball locations, you can instantly select either 10mm or 19mm of wheelbase extension without requiring any special tools or technical expertise. This means you can experiment with different wheelbase settings at the track, in the garden, or at your local RC racing venue, finding the perfect balance for varying ground conditions and driving styles. For UK RC car enthusiasts seeking to get more performance from their existing Revo, E-Revo or Summit platform, this is precisely the kind of targeted upgrade that separates competitive setups from stock configurations.

Installation is genuinely straightforward, and Traxxas has engineered the system to work seamlessly with your existing suspension components. The fact that you can tune your wheelbase quickly and repeatedly means you're not locked into one configuration—you can adapt your RC car's geometry as conditions change or as you discover what works best for your driving style. This level of adjustability at such an affordable price point makes the TRX5333R an excellent investment for anyone serious about maximising their RC car's potential.

Key Features

• Adjustable Wheelbase Extension — You can add either 10mm or 19mm of wheelbase extension by simply repositioning the pivot ball locations on the suspension arms, allowing you to tune your RC car's geometry for different track conditions and driving preferences without purchasing multiple suspension arm sets.
• Snap Installation — Installation is designed to be quick and straightforward, meaning you can make wheelbase adjustments in just minutes rather than spending hours on suspension modifications, which is particularly valuable when you're at a race event or practice session and need to make trackside adjustments.
• Trackside Tuneability — The ability to quickly adjust your wheelbase at the track means you can respond to changing conditions throughout the day, experimenting with different geometries to find the optimal setup that maximises traction, reduces understeer or oversteer, and improves overall handling characteristics.
• Complete Suspension Arm Set — The package includes suspension arm upper components (2 pieces), suspension arm lower components (2 pieces), bumper mount spacers (2 pieces), and fasteners (4x16BCS, 2 pieces), providing everything needed for installation without requiring additional purchases.
• Compatible with Multiple Platforms — This suspension arm set is designed to work with Traxxas Revo, E-Revo and Summit models, making it accessible to a broad range of RC car owners within the Traxxas ecosystem.
• Genuine Traxxas Engineering — As an official Traxxas component, the TRX5333R undergoes rigorous quality control and testing, ensuring compatibility, durability and reliable performance over repeated use and adjustments.

Technical Performance

The Traxxas Suspension arm Set TRX5333R represents precision suspension engineering designed to work seamlessly with the Revo, E-Revo and Summit platforms. The adjustable pivot ball system allows for controlled wheelbase geometry modification, which directly influences suspension kinematics, weight transfer characteristics and overall vehicle dynamics. By extending the wheelbase by 10mm or 19mm, you're effectively adjusting the longitudinal weight distribution envelope and altering the way your RC car's suspension responds to acceleration, braking and cornering forces. The inclusion of both upper and lower suspension arm components ensures balanced geometry modification, maintaining proper suspension travel and preventing unwanted binding or geometry conflicts. The bumper mount spacers accommodate the extended wheelbase configuration, maintaining structural integrity and ensuring all mounting points align correctly. The provision of 4x16BCS fasteners (2 pieces) ensures secure attachment to the suspension tower. It's worth noting that if you intend to use 5451R driveshafts with your extended wheelbase configuration, you'll require 5153R drive cups to maintain proper driveline geometry and prevent binding. The engineering philosophy behind this system reflects Traxxas's commitment to modular, user-friendly suspension tuning that doesn't require specialist knowledge or equipment to implement.

Frequently Asked Questions

• How much wheelbase extension does the TRX5333R provide? — The Traxxas Suspension arm Set offers two wheelbase extension options: 10mm or 19mm, selectable by repositioning the pivot ball locations on the suspension arms, allowing you to choose the configuration that best suits your track conditions and driving style.
• Is installation complicated or will I need professional help? — No, installation is designed to be straightforward and can be completed in just minutes without specialist tools or technical knowledge, making it accessible to RC car owners of all experience levels, whether you're a seasoned competitor or relatively new to the hobby.
• Can I adjust the wheelbase at the track without bringing spare parts? — Yes, one of the key advantages of the TRX5333R is trackside tuneability; you can quickly adjust between the 10mm and 19mm settings at the track to respond to changing conditions and optimise your setup throughout the day.
• Which Traxxas models is this suspension arm set compatible with? — The TRX5333R is designed for Traxxas Revo, E-Revo and Summit models, making it suitable for a broad range of Traxxas enthusiasts in the UK RC community.
• Do I need any additional components to use this suspension arm set? — If you're using 5451R driveshafts with the extended wheelbase configuration, you'll need to purchase 5153R drive cups separately to maintain proper driveline geometry and prevent binding or drivetrain strain.
• What is the performance benefit of extending the wheelbase? — Wheelbase extension generally improves longitudinal stability, reduces weight transfer sensitivity, and can decrease understeer characteristics—particularly useful on high-grip surfaces or when you need more predictable handling throughout corner entry, apex and exit phases.
