Technical Performance

These Traxxas GTR shocks represent the pinnacle of RC suspension engineering, crafted from premium-grade blue anodised aluminium that combines lightweight construction with exceptional durability and corrosion resistance. The 139mm length is precisely calculated for optimal rear-end suspension performance, providing the ideal balance between compression and rebound characteristics needed for aggressive driving on sand, dirt, rocks and mixed terrain. The threaded shock bodies deliver unrestricted ride height adjustment, a critical feature for competitive RC racing where suspension geometry directly impacts handling precision, traction and overall vehicle responsiveness. As fully assembled components, these shocks eliminate assembly variables and potential fitment issues, ensuring consistent performance right out of the box. The engineering excellence evident in these components makes them an essential choice for anyone serious about maximising their RC vehicle's potential, whether competing in UK RC championships, recreational off-road bashing, or professional racing applications. The decision to exclude springs allows experienced RC builders complete control over suspension tuning, a significant advantage when dialling in your vehicle for specific courses, weather conditions, or driving techniques.

Frequently Asked Questions

• Are these shocks compatible with my Traxxas UDR? — Yes, these GTR shocks are specifically engineered for the Traxxas Unlimited Desert Racer Pro-Scale 4WD and compatible UDR variants. The 139mm length with threaded bodies is the correct specification for rear suspension on these models. Always verify your chassis model and suspension position (front or rear) before purchasing, as Traxxas offers different shock lengths for front and rear applications.
• Why are springs not included with these shocks? — Traxxas supplies these shocks without springs to give experienced builders complete control over suspension tuning. Different spring rates significantly affect vehicle handling, and by purchasing springs separately, you can select rates that match your specific driving weight, skill level, and intended use. Lighter drivers may prefer softer springs, whilst heavier drivers or competitive racers often prefer stiffer springs for more precise control.
• Can I adjust the ride height with these shocks? — Absolutely. The threaded shock bodies allow you to adjust ride height precisely without requiring additional spacers or collars. Simply thread the shock body up or down to achieve your desired ride height, then secure it with the collars provided in your vehicle kit. This adjustability is essential for fine-tuning your suspension geometry for different terrain and racing conditions.
• What makes blue anodised shocks different from silver or red options? — Traxxas offers GTR shocks in blue, red and silver anodised finishes. The anodising process is identical across all colours, providing the same durability and corrosion resistance benefits. The choice is purely aesthetic, allowing you to match your vehicle's colour scheme or personal preference. All anodised finishes are significantly more durable than bare aluminium.
• Are these shocks suitable for beginners or only advanced users? — These shocks are suitable for all skill levels. Traxxas manufactures OEM suspension components to exacting standards, meaning installation and basic operation is straightforward. However, optimising suspension tuning by selecting appropriate spring rates and adjusting ride height is more of an intermediate to advanced skill. Beginners can absolutely use these shocks with guidance from experienced RC enthusiasts, whilst advanced racers will appreciate the precise adjustment capabilities for competition-level setup.
• How do I know which shock length I need for my UDR? — The Traxxas UDR uses different shock lengths for front and rear suspension. These are specifically 139mm rear shocks with threaded bodies. Front shocks are shorter (typically 134mm) and may have different specifications. Always check your vehicle's manual or contact RC specialists to confirm you're ordering the correct position and length before purchasing.
• What spring rate should I choose for these shocks? — Spring rate selection depends on several factors: your driving weight, driving style, terrain type and vehicle purpose. Lighter drivers or those seeking softer, more compliant suspension typically choose lower spring rates. Heavier drivers and competitive racers generally prefer stiffer springs for more responsive handling. Traxxas publishes spring recommendations for different applications, and consulting RC specialists in the UK can help you select the perfect rate for your needs.
