Traxxas Shock Springs 0.54 Rate GTS Platform Pair TRX8040

Overview

The Traxxas Springs, shock (natural finish) (GTS) (0.54 rate, Green stripe) (2 pcs) TRX8040 are premium replacement suspension springs designed for serious RC enthusiasts who demand reliable performance from their Traxxas TRX-4 crawlers. These genuine Traxxas springs are engineered to deliver consistent handling and suspension response, whether you are tackling challenging terrain at your local RC track or enjoying weekend bashing with fellow RC car UK enthusiasts. The natural finish combined with the distinctive green stripe makes these springs easily identifiable on your model, whilst their carefully calibrated 0.54 rate ensures optimal suspension geometry for trail crawling and off-road exploration.

If you own a Traxxas TRX-4 platform RC crawler, the TRX8040 springs are an essential spare part to keep in your toolbox. Over time, suspension springs wear and lose their original spring rate, affecting handling, ride height and overall performance. These replacement springs restore your crawler's suspension characteristics to factory specification, ensuring your vehicle maintains its intended setup for accurate driving dynamics and predictable cornering behaviour. Whether your TRX-4 is getting heavier with additional upgrades or you simply want to maintain peak performance, having a spare set of genuine Traxxas springs ensures you are never stuck on the sidelines waiting for parts to arrive.

As an authorised Traxxas retailer, RC Model Shop stocks only genuine Traxxas components. These are not cheap aftermarket copies—they are the exact same springs that come fitted to new TRX-4 models from the factory, ensuring perfect compatibility and performance. The two-piece pack gives you the option to replace both rear springs or keep one as a backup, which is practical thinking for any serious RC hobbyist who wants to minimise downtime during competitions or casual play sessions.

Key Features

• 0.54 Spring Rate — This spring constant is specifically engineered for the GTS suspension platform used in Traxxas TRX-4 crawlers, providing the ideal balance between suspension travel and support, ensuring your vehicle maintains proper ride height and handling characteristics whether you are crawling over rocks or navigating loose terrain.
• Natural Finish Construction — The natural finish indicates these are genuine Traxxas OEM (original equipment manufacturer) springs, not painted or coated alternatives, which means they are manufactured to the exact same tolerances and specifications as the springs fitted to factory TRX-4 models.
• Green Stripe Identification — The distinctive green stripe running along the spring makes it immediately obvious which spring rate you are using, helping you quickly identify components and prevent mixing different rates if you are tuning multiple vehicles or testing suspension setups.
• Pair Pack (2 Pieces) — This pack includes two springs, allowing you to replace both rear springs or keep one as a spare, which is essential for maintaining uninterrupted RC driving sessions without waiting for replacement parts to arrive.
• Genuine Traxxas OEM Component — These are official factory springs, not third-party reproductions, guaranteeing perfect fit and function with your TRX-4 crawler without any compatibility issues or fitment surprises.
• GTS Platform Compatibility — Specifically designed for the GTS (Generation Two) suspension platform used across the TRX-4 range, ensuring these springs work flawlessly with all compatible models in the Traxxas TRX-4 family.

Technical Performance

The Traxxas Springs TRX8040 represent the gold standard in replacement suspension components for serious RC crawler enthusiasts across the UK. With a precisely calibrated 0.54 spring rate, these springs are engineered to provide the perfect balance of suspension support and travel range essential for trail crawling and rock-crawling applications where traction and precise vehicle control are paramount. The spring rate directly affects how your TRX-4 handles, controlling how quickly the suspension compresses under load and how effectively it returns to its original position, which in turn affects ride height, body roll, and how your crawler responds to terrain changes. A 0.54 rate is the standard specification for rear suspension in many TRX-4 variants, making these springs an ideal replacement for original equipment that has fatigued after extended use. Traxxas engineers these springs using high-quality spring steel that maintains its elastic properties over thousands of compression cycles, ensuring consistent performance lap after lap, session after session. The natural finish coating protects the steel from corrosion whilst maintaining the authentic Traxxas factory appearance, and the green stripe makes instant identification of spring rate easy when you are comparing setups or troubleshooting suspension issues. Whether your crawler has accumulated heavy use over months of weekend bashing or you are proactively maintaining your fleet of ready to run RC models, installing fresh springs restores your vehicle's suspension to its original responsive characteristics, improving handling precision and ensuring your setup performs as intended by Traxxas engineers.

Frequently Asked Questions

• What Traxxas TRX-4 models are compatible with the TRX8040 springs? — The TRX8040 springs are compatible with an extensive range of Traxxas TRX-4 crawlers, including the Chevrolet K10 Cheyenne High Trail Edition (available in Black, Metallic Copper, Red, and Metallic Blue), the Ford F-150 Ranger XLT High Trail Edition (available in Blue, Black, and Brown), the 1972 Chevrolet K5 Blazer High Trail Edition (available in Red and Blue), the 1979 Chevy Blazer with Clipless Body (available in Red and Black), the Nissan Pathfinder SE-V6 3S (available in Silver and Red), the 2021 Ford Bronco (available in Orange, Black, Red, and White), the TRX-4 Defender (available in Green, Sand, Red, and Silver), the TRX-4 Sport High Trail Edition and Sport variants with Clipless Body, and the TRX-6 Ultimate RC Hauler. If you own any TRX-4 platform crawler, these springs are highly likely to fit your model.
• Why would I need replacement suspension springs for my RC crawler? — Springs gradually lose their spring rate through normal use as the metal fatigues after thousands of compression and extension cycles. Over time, your vehicle's ride height drops, handling becomes mushy, and the precise control you had when the crawler was new deteriorates. Additionally, if you are upgrading your TRX-4 with heavier body panels, winches, or other accessories, you may need stiffer springs to maintain correct ride height and handling. Fresh springs restore your suspension to factory specification and bring back the responsive handling that makes RC crawling enjoyable.
• Are these genuine Traxxas springs or aftermarket alternatives? — The TRX8040 springs are genuine Traxxas OEM (original equipment manufacturer) parts, identical to those fitted to new TRX-4 models from the factory. These are not aftermarket reproductions or generic springs—they are the real thing, engineered and manufactured by Traxxas to exact specifications. Choosing genuine components ensures perfect compatibility and performance with your TRX-4.
• What does the 0.54 spring rate mean? — Spring rate measures how much force is required to compress a spring by a specific distance, typically expressed in kilograms per centimetre or pounds per inch. A 0.54 rate spring is a standard specification for many TRX-4 models, offering a good balance between suspension support and travel. Stiffer (higher) rates compress less and keep the vehicle higher off the ground; softer (lower) rates compress more and allow greater suspension travel. The 0.54 rate is engineered to work perfectly with the GTS suspension platform used in TRX-4 crawlers.
• Can I mix different spring rates on my RC crawler? — Technically yes, but it is not recommended for balanced handling. Mixing spring rates between front and rear, or left and right sides, creates asymmetrical suspension geometry that can cause unpredictable handling behaviour. For best results, replace springs as matching pairs and maintain consistent rates across all suspension corners of your vehicle.
• Is this suitable for beginners? — Yes, the TRX8040 springs are suitable for any RC enthusiast, from beginners to experienced competitors. They are simple to install—no specialist tools required beyond basic hex drivers and Allen keys—and they are essential maintenance items that every TRX-4 owner should keep as spares. If you are new to RC crawling, having spare springs ensures you can continue enjoying your hobby without interruption if suspension components wear out.
