Traxxas GTR Shocks 134mm Silver Aluminium Front Pair RC TRX8451

Overview

The Traxxas Shocks, GTR, 134mm, Silver aluminium (fully assembled without springs) (Front, no threads) (2 pcs) TRX8451 are professional-grade suspension components engineered specifically for the Traxxas Unlimited Desert Racer (UDR) platform. These oil-filled long-travel dampers deliver silky-smooth damping performance that tames the toughest desert terrain, making them an essential upgrade for anyone serious about high-speed off-road RC racing and jumping. Whether you're a seasoned competitor pushing your RC car UK setup to its limits or an enthusiast looking to enhance your UDR's suspension capabilities, these GTR shocks represent Traxxas's commitment to precision engineering and reliable performance on challenging terrain.

Built from silver anodised aluminium and measuring 134mm in eye-to-eye length, these shocks are factory-assembled and pre-filled with silicone oil, ready for installation on the front axle of your UDR. The no-thread design provides a clean, streamlined finish while maintaining structural integrity, and the sealed construction with O-ring technology minimises leakage during intense driving sessions. This is a genuine Traxxas spare part that offers the quality and durability you expect from an authorised retailer stocking genuine RC components.

These shocks are sold as a fully assembled pair without springs, meaning springs are sold separately and must be purchased based on your preferred suspension setup and driving style. The modular design allows for easy servicing and tuning, making them ideal for both casual weekend bashers and competitive racers who want to fine-tune their suspension geometry for optimal performance on sand, gravel, or rocky terrain.

Key Features

• Oil-filled 134mm long-travel design — The 134mm eye-to-eye length provides extended suspension travel that absorbs impacts from rough terrain whilst maintaining consistent damping performance, crucial for high-speed desert racing where absorption of big hits directly translates to vehicle control and speed maintenance.
• Silver anodised aluminium construction — The lightweight aluminium body reduces unsprung weight on your RC car, which improves overall vehicle control, responsiveness, and acceleration whilst the anodised finish provides durability and a professional appearance that resists corrosion during outdoor use.
• Pre-filled with silicone oil — The factory silicone oil fill ensures consistent, predictable damping behaviour out of the box, though they can be drained and refilled with different oil viscosities to tune your suspension stiffness based on track conditions and driving preferences.
• Fully assembled without springs — These shocks arrive completely assembled and ready to install, saving you setup time, though springs must be purchased separately, allowing you to select the exact spring rates that match your weight, driving style, and terrain preferences.
• Front-specific design with no threads — The no-thread design eliminates external fasteners from the shock body, creating a clean, smooth profile that fits perfectly in the front suspension mounting position of your UDR without snagging or catching on terrain.
• Sealed design with O-ring technology — The advanced sealing system minimises oil leakage during intense driving, maintaining consistent damping performance throughout your racing session and extending the service life of the shock assembly.
• Integrated shock cap and piston shaft guide — The precision-engineered piston rod guide ensures smooth, binding-free operation whilst the integrated shock cap provides structural support and a clean aesthetic, contributing to the shock's overall reliability and longevity.
• Compatible with Traxxas silicone shock oils — You can easily tune your suspension by swapping out the oil for different viscosity Traxxas silicone oils, allowing experienced RC enthusiasts to fine-tune damping characteristics for specific tracks or weather conditions.
• Precision CNC-machined components — Every internal component is CNC-machined to tight tolerances, ensuring consistent performance across the pair and providing the durability needed for competitive racing and high-impact jumping.
• Modular design for easy servicing — The shock construction allows for straightforward disassembly, cleaning, oil changes, and component replacement, making maintenance and tuning accessible even if you're new to RC car UK hobby mechanics.
• Sold as a matched pair — These two shocks are designed to work together on your UDR's front axle, ensuring balanced suspension geometry and predictable handling across both front wheels for stable, controlled driving.

Technical Performance

The Traxxas GTR 134mm shocks represent the pinnacle of suspension engineering for the Unlimited Desert Racer platform. Constructed from precision CNC-machined components and finished in silver anodised aluminium, these shocks deliver the advanced damping performance required for high-speed off-road racing and aggressive jumping. The 134mm length provides optimal travel for both front and rear suspension positioning, though this particular product is specifically optimised for front-axle mounting. The oil-filled design with integrated O-ring sealing technology ensures that damping remains consistent even when driving through water crossings, sand storms, or rocky terrain where dust and moisture would otherwise compromise performance. The lightweight aluminium construction directly contributes to reduced unsprung weight, which improves vehicle control, acceleration, and overall responsiveness—critical factors when you're trying to maximise your RC buggy or short-course truck's performance on demanding terrain. The fully assembled configuration means these shocks are ready to install immediately upon arrival, though you'll need to source appropriate springs separately, allowing you to tailor spring rates to your specific setup. The modular design permits easy oil changes and component servicing, meaning you can adjust damping characteristics throughout the season to match varying track conditions, temperature, and humidity levels. These shocks are engineered to integrate seamlessly with other Traxxas UDR components and are compatible with Traxxas silicone shock oils in various viscosities, giving you precise control over suspension tuning. Whether you're navigating fast sand whoops, technical rock gardens, or competitive racing environments, the GTR shock's combination of durability, consistent performance, and adjustability makes it an investment in your RC car UK racing future.

Frequently Asked Questions

• Are these GTR shocks suitable for my Traxxas UDR? — Yes, these shocks are engineered specifically for Traxxas Unlimited Desert Racer (UDR) platforms, including both the Pro-Scale 4WD RTR Short Course Truck with Rigid Industries (TRX85086-4-RGD1) and Fox Racing (TRX85086-4-FOX1) variants. They are an official Traxxas upgrade part designed to fit perfectly within your UDR's suspension geometry.
• Why do these shocks come without springs? — Springs are sold separately because different RC enthusiasts require different spring rates based on their weight, driving style, and the specific terrain they're racing on. By offering shocks without springs, Traxxas allows you to select the exact spring stiffness that matches your setup rather than being locked into a one-size-fits-all configuration.
• Are these shocks pre-assembled and ready to use? — Yes, these GTR shocks arrive fully assembled and pre-filled with silicone oil, requiring no internal setup before installation. However, you will need to fit your chosen springs and install the complete shock assembly onto your vehicle's front suspension mounting points.
• Can I tune the damping on these shocks? — Absolutely. You can adjust the damping characteristics by draining and replacing the factory silicone oil with alternative viscosity Traxxas shock oils. Higher viscosity oil provides stiffer damping for harder terrain and high speeds, whilst lower viscosity oil offers softer, more compliant damping for technical sections and rough surfaces.
• What does the no-threads design mean? — The no-threads design means there are no external threaded fasteners protruding from the shock body, creating a smooth, streamlined profile that resists snagging on terrain and provides a cleaner aesthetic. This is particularly valuable when driving through tight spaces or over jagged rocks.
• How long do these shocks last? — With proper maintenance and appropriate spring selection, these precision CNC-machined shocks offer exceptional longevity. The sealed O-ring design minimises oil leakage and internal wear, though you should inspect them regularly and perform occasional maintenance such as cleaning and oil replacement to maintain peak performance throughout the racing season.
• What is the shock length specification? — These shocks measure 134mm in eye-to-eye length, which is the industry standard for Traxxas UDR front suspension applications and provides the extended travel necessary for high-speed desert racing and aggressive jumping.
• Are these suitable for beginners? — Whilst these shocks are suitable for RC enthusiasts at all skill levels, they are particularly valued by experienced racers and tuners who appreciate the ability to fine-tune suspension characteristics. Beginners can certainly use them, but should ensure they understand basic suspension geometry and have access to the appropriate springs before installation.
• What material are these shocks made from? — These GTR shocks feature a silver anodised aluminium body, which provides an excellent strength-to-weight ratio. The anodising process creates a hard, corrosion-resistant finish that protects the aluminium from oxidation and damage during outdoor use in desert environments.
• How do I know which springs to buy? — Spring selection depends on your weight, driving style, and intended terrain. Traxxas offers springs in various rates; stiffer springs suit heavier drivers and high-speed racing, whilst softer springs work better for lighter drivers and technical terrain. Consult your UDR's documentation or speak with an RC expert when selecting springs.
