Traxxas Spring retainer (adjuster), Blue-anodised aluminium, GTX shocks (4 pcs) (assembled with o-ring) TRX7767

Overview

The Traxxas Spring Retainer (Adjuster) in stunning blue-anodised aluminium is an essential upgrade for owners of Traxxas X-Maxx and XRT RC monster trucks and rock crawlers across the UK. Whether you're a seasoned RC enthusiast looking to fine-tune your suspension setup or someone new to the hobby of remote control vehicles, these precision-engineered components will dramatically improve your driving experience. These spring retainers represent the quality and attention to detail that Traxxas is renowned for throughout the RC car and truck community.

Spring retainers are critical suspension components that hold your shock springs in place while allowing you to adjust the spring pre-load with precision. The pre-load setting directly affects how your vehicle handles during acceleration, braking, cornering and rough terrain traversal. With these four retainers, you'll have complete control over your suspension geometry and can dial in the perfect setup for your particular driving style, track conditions or bashing terrain. Whether you're tackling a local RC racing circuit, hitting a motocross track with your RC monster truck, or exploring rocky woodland trails, getting your spring pre-load right makes an enormous difference to performance, handling and longevity.

Available now at RC Model Shop, these Traxxas suspension components come as a genuine OEM part, ensuring perfect fitment and reliability on your X-Maxx Ultimate, X-Maxx Belted, or XRT Ready to Run RTR RC truck. The integrated O-ring design means you won't lose parts or struggle with assembly – everything arrives pre-assembled and ready to install on your RC off-road vehicle.

Key Features

• Blue-Anodised Aluminium Construction — The body of these spring retainers is machined from high-quality aluminium and finished with a protective blue anodised coating, which not only looks fantastic but also provides excellent corrosion resistance and durability. This means your suspension components will maintain their appearance and structural integrity through countless hours of driving, whether you're bashingUK trails or competing in RC racing events.
• Integrated O-Ring Design — Each of the four retainers comes equipped with a factory-installed O-ring that is already assembled and ready to use. This eliminates the hassle of sourcing separate O-rings or struggling with installation, and ensures perfect seating and function right out of the box. The O-ring prevents your shock springs from sliding off and allows smooth, reliable spring pre-load adjustment.
• Precision Spring Pre-Load Adjustment — These retainers enable you to make fine adjustments to your spring pre-load, which directly affects suspension ride height, stiffness and responsiveness. By adjusting the pre-load up or down, you can customise how your X-Maxx or XRT responds to bumps, jumps and cornering forces, giving you the ability to optimise your RC truck's handling for different terrains and driving conditions.
• Set of Four Retainers — You receive a complete set of four retainers, meaning you can replace or upgrade all four corners of your suspension in one purchase. This ensures consistent suspension geometry across your entire vehicle and provides you with spares in case of damage.
• Genuine Traxxas OEM Component — These are official Traxxas parts designed and manufactured to exact specifications for perfect fitment on compatible X-Maxx and XRT models. Using genuine OEM components ensures reliability and maintains your vehicle's warranty and performance characteristics.
• Compatible with GTX Shocks — These spring retainers are specifically designed for use with Traxxas GTX shocks, which are found on modern X-Maxx and XRT vehicles. The GTX shock range is renowned for offering excellent damping, stability and durability in both racing and bashing applications.

Technical Performance

The Traxxas Spring Retainer is engineered with the same precision that Traxxas brings to all its suspension components. The blue-anodised aluminium is a premium material choice that offers an excellent strength-to-weight ratio – crucial for maintaining optimal suspension responsiveness whilst keeping unsprung weight as low as possible on your RC monster truck or crawler. The anodising process creates a hard oxide layer on the surface that resists scratches, corrosion and fading from UV exposure, meaning these components will look great and perform reliably for years. The integrated O-ring comes pre-installed and pre-positioned, which means no fiddly assembly – simply install the retainers onto your shocks and you're ready to adjust your spring pre-load. The retainer design allows tool-free adjustment of pre-load by rotating it on the shock body, making trackside adjustments quick and straightforward when you need to fine-tune your setup for changing conditions. These retainers are compatible with all versions of the X-Maxx including the X-Maxx Belted 4WD Brushless RTR 8S Monster Truck (available in Red, Green, Orange and Blue), the X-Maxx Ultimate variants (Green X and Blue X), the X-Monster Chassis, and all variants of the XRT including the XRT VXL-8S (Blue, Orange, Green and Black) and XRT Ultimate (Green X and Blue X). Whether you're running your RC truck on high-grip tarmac, loose gravel, sand or rocky terrain, these spring retainers will give you the adjustment range needed to optimise your suspension for maximum performance and control.

Frequently Asked Questions

• What is a spring retainer and why do I need one for my RC monster truck? — A spring retainer is a suspension component that holds your shock spring in place on the shock body and allows you to adjust the spring pre-load. Pre-load adjustment changes how much the spring is compressed when at rest, which affects your vehicle's ride height, suspension stiffness, and how it responds to bumps and corners. By adjusting pre-load, you can customise your RC truck's handling for different track conditions, terrain types and driving styles – whether you're racing on a prepared surface or bashing through rough woodland.
• Are these spring retainers compatible with my Traxxas X-Maxx or XRT? — Yes, these Traxxas TRX7767 spring retainers are designed specifically for X-Maxx and XRT models equipped with GTX shocks. They are compatible with all X-Maxx variants (Belted 4WD Brushless RTR 8S in Red, Green, Orange and Blue, and X-Maxx Ultimate in Green X and Blue X), the X-Monster Chassis, and all XRT models (XRT VXL-8S in Blue, Orange, Green and Black, and XRT Ultimate in Green X and Blue X). Always verify your specific model before ordering.
• Do the retainers come pre-assembled? — Yes, these spring retainers arrive fully assembled with the O-ring already installed and positioned. This means you can install them directly onto your shocks without any additional assembly or sourcing separate O-ring components – simply unbox and fit to your vehicle.
• How do I adjust the spring pre-load using these retainers? — Spring pre-load is adjusted by rotating the retainer on the shock body. Clockwise rotation typically increases pre-load (making the suspension stiffer and raising ride height), whilst anti-clockwise rotation decreases pre-load (softening the suspension and lowering ride height). Make small adjustments and test your vehicle's handling to find the optimal setting for your driving conditions and style.
• What is the benefit of the blue-anodised aluminium finish? — The anodised aluminium not only gives these retainers a stunning appearance that matches many modern Traxxas components, but also provides excellent protection against corrosion, UV fading and general wear. This means your suspension components will maintain their finish and functionality through countless hours of use in the UK's variable weather conditions, whether you're driving in wet conditions, dusty terrain or bright sunshine.
• Can I replace just one retainer or do I have to buy a full set of four? — You receive a set of four retainers in this package. Ideally, it's best practice to replace all four corner retainers at the same time to ensure consistent suspension geometry and handling across your entire vehicle. However, if you only need to replace one or two, you can order multiple packages or contact RC Model Shop to discuss your specific needs.
