Traxxas Ultra Shocks Long Grey Oil-Filled RC Suspension with Springs TRX3760A

Overview

The Traxxas Ultra Shocks (Grey) (Long) (TRX3760A) are a premium suspension upgrade designed for RC enthusiasts who demand plush damping and super-smooth performance from their vehicles. Whether you're running a Traxxas Slash HD or another compatible RC short course truck, these complete front shocks deliver the refined handling characteristics that serious RC car UK drivers expect. This is not just a basic spare part—it's a complete suspension solution that transforms how your RC model responds to terrain, offering the kind of refinement you'd find in competition-grade setups.

These shocks represent Traxxas's commitment to performance engineering, combining oil-filled damping technology with precision-engineered components to give your RC vehicle the competitive edge. The complete front set comes fully assembled and ready to install, meaning you can upgrade your suspension without needing specialised tools or technical knowledge. For anyone looking to improve their ready to run RC truck or enhance their weekend bashing experience, these Ultra Shocks offer exceptional value and proven reliability that Traxxas is renowned for across the UK RC community.

Ideal for drivers of all experience levels—from those new to the hobby discovering their first suspension upgrade to seasoned racers fine-tuning their setups—these shocks are compatible with multiple Traxxas Slash HD variants in all colour options. The grey finish complements most RC truck colour schemes, while the engineering inside ensures consistent, predictable handling that helps you learn and improve your driving.

Key Features

• Oil-filled design with X-ring seals — The shock bodies are filled with precision-blended shock oil and feature X-ring seals that provide a perfect seal, preventing fluid leakage and ensuring your suspension maintains consistent performance over extended driving sessions and through various weather conditions encountered in UK RC racing and bashing.
• Pre-assembled grey shock bodies — Both shocks arrive fully assembled in an attractive grey colour, eliminating the need for time-consuming assembly work and ensuring professional-quality construction right out of the box, allowing you to install them immediately on your RC model.
• Long format shocks — The extended length of these shocks provides increased suspension travel and allows for more sophisticated damping characteristics, translating to improved ride quality, better cornering control, and superior stability when driving across rough terrain or at higher speeds.
• Included pre-load spacers — These precision-engineered spacers allow you to fine-tune the spring pre-load to match your driving style, track conditions, and vehicle weight distribution, giving you control over ride height and suspension stiffness without purchasing additional components.
• Complete spring set included — Two springs are supplied with this kit, eliminating the need for separate purchases and ensuring your suspension is perfectly matched from the factory, with springs designed specifically for long-format Ultra Shocks to deliver optimal performance.
• Shock oil supplied — The complete kit includes shock oil for immediate installation and future maintenance, ensuring you have everything needed to keep your suspension performing at its best throughout the life of your RC truck.

Technical Performance

These Traxxas Ultra Shocks represent the pinnacle of suspension engineering for 1/10 scale RC short course trucks and similar platforms. The oil-filled construction with X-ring seals delivers the plush damping that separates premium shocks from basic alternatives—the shock oil absorbs and dissipates energy smoothly, preventing harsh jolts from rocks, jumps and obstacles whilst maintaining consistent damping characteristics even as temperatures fluctuate during extended driving sessions. This is crucial for UK RC drivers who may experience variable weather conditions throughout the year. The long format construction allows greater suspension travel compared to standard shocks, which means your truck maintains better tyre contact with the ground during acceleration, braking and cornering, directly improving handling and traction. The pre-load spacers enable precise tuning of the suspension geometry; adjusting pre-load affects ride height, which influences weight transfer and handling balance—critical factors whether you're racing competitively or enjoying casual weekend bashing. The included springs have been engineered specifically for these long shocks, ensuring the suspension characteristics remain predictable and controllable across the full range of pre-load adjustment. Built to Traxxas's exacting standards, these shocks represent years of suspension development and real-world testing in racing environments, making them trusted components used by professional RC drivers globally.

Frequently Asked Questions

• Which Traxxas RC models are these Ultra Shocks compatible with? — These long grey shocks are specifically designed for the Traxxas Slash HD XL-5 1/10 2WD RTR Short Course Truck, with compatibility confirmed across all colour variants including orange, blue, green and red models. If you own a different Traxxas model, we recommend checking compatibility before purchasing, as shock length and mounting specifications vary between models.
• Are these shocks suitable for beginners? — Yes, absolutely. Whilst these are premium performance components, they're designed to be straightforward to install and don't require any special mechanical skills beyond basic RC truck maintenance. The included pre-load spacers allow beginners to start with factory settings and gradually experiment with tuning as they gain experience and understanding of how suspension affects handling.
• What makes oil-filled shocks better than standard shocks? — Oil-filled shocks deliver smoother, more consistent damping because the shock oil continuously absorbs and controls the movement of the shock shaft, preventing harsh impacts and providing progressive damping throughout the suspension stroke. This results in better tyre contact with terrain, improved traction, and a more refined driving experience compared to dry shocks that can feel harsh and unpredictable.
• What is the purpose of the pre-load spacers? — Pre-load spacers allow you to adjust how tightly the spring is compressed before any suspension movement occurs. By adding or removing spacers, you can change your vehicle's ride height and alter how stiff the suspension feels, enabling you to tune the setup for different track conditions, driving styles or vehicle weights without purchasing new springs.
• Are these shocks easy to maintain? — Yes, these shocks are designed for straightforward maintenance. The kit includes shock oil for refilling if needed after extended use. Over time, suspension oil can gradually leak or separate, so periodic inspection and topping up with the provided oil ensures continued optimal damping performance and extends the lifespan of your shocks.
• What's the difference between long and short shocks? — Long format shocks provide greater suspension travel, allowing the shock body to extend and compress over a longer distance. This translates to better ground clearance, improved ride quality over obstacles, and the ability to tune suspension characteristics more precisely. Short shocks are typically used on other Traxxas models and aren't compatible with vehicles designed for long shocks, so always verify which format your RC model requires.
