Overview
The Fastrax 1/10th 55mm Alloy Adjustable Shocks (Pair) FAST155 are premium suspension components designed for RC enthusiasts who demand precision handling and reliable performance from their 1/10 scale RC cars. Whether you're running a Traxxas model, an ARRMA vehicle, or any other compatible 1/10 scale RC car in the UK, these adjustable shocks offer the tuning flexibility needed to dial in your suspension setup for various track conditions and driving styles. Suspension is one of the most critical aspects of RC car performance, and having quality, adjustable shocks allows you to optimise your vehicle's ride height, dampening characteristics, and overall stability during both casual bashing sessions and competitive racing.
These aluminium shock bodies represent a significant upgrade over basic plastic alternatives found on many entry-level RC kits. The adjustable nature of these shocks means you're not limited to a single setup — you can fine-tune your suspension to suit different terrains, from smooth tarmac circuits to rougher off-road tracks. For RC car enthusiasts in the UK looking to improve their vehicle's handling characteristics and get the most out of their models, investing in quality adjustable shocks like the Fastrax FAST155 is a smart decision that will pay dividends in improved control and consistency.
The 55mm length makes these shocks suitable for a wide variety of 1/10 scale vehicles, including buggies, touring cars, and short course trucks. If you're searching for RC suspension upgrades in the UK or need replacement shocks for your existing model, the Fastrax adjustable shock range has earned a reputation for delivering excellent value without compromising on quality or performance.
Key Features
- Adjustable Design — These shocks feature fully adjustable construction, allowing you to fine-tune your suspension setup to match your driving style, track conditions, and vehicle weight distribution, which is essential for achieving optimal handling characteristics in competitive racing or recreational bashing.
- Aluminium Construction — The alloy shock bodies provide superior strength and durability compared to plastic alternatives, whilst remaining lightweight to avoid adding unnecessary unsprung mass that could negatively impact your RC car's performance and responsiveness.
- 55mm Length — This specific length is engineered to work with the majority of 1/10 scale RC vehicles, making these shocks a versatile upgrade option compatible with multiple chassis designs and models from leading manufacturers.
- Supplied as Pair — You receive two complete shocks in this package, which is the standard configuration for front or rear suspension installation, providing convenient matching performance across your RC car's suspension system.
- Requires Shock Oil — These shocks are designed to be filled with quality shock oil, which you'll need to purchase separately, allowing you to select the exact viscosity that suits your specific driving conditions and tuning preferences for complete suspension control.
- Compatible with Multiple Brands — These Fastrax shocks are engineered to fit various 1/10 scale platforms including Element Enduro, HPI, Mugen, Tamiya, Team Associated, Team Losi, Traxxas TRX-4, and Axial Racing models, making them an excellent universal suspension upgrade option.
Technical Performance
The Fastrax 1/10th 55mm Alloy Adjustable Shocks represent quality suspension engineering designed specifically for 1/10 scale RC vehicles. The aluminium construction offers excellent strength-to-weight ratio, which is crucial in RC applications where every gram of unsprung mass affects handling, suspension response, and overall vehicle dynamics. The adjustable nature of these shocks means you have direct control over suspension geometry and dampening rates through oil viscosity selection and internal adjustment mechanisms. The 55mm length is precisely engineered to fit within the suspension geometry of most popular 1/10 scale platform designs, whether you're running buggies, touring cars, crawlers, or short course trucks. The shocks come ready to be assembled and filled with shock oil of your choice, giving you complete flexibility in tailoring your suspension to your exact requirements. The pair configuration ensures balanced performance across your vehicle, and the quality construction means these shocks will withstand the rigours of regular RC car use, whether you're racing competitively or enjoying casual weekend bashing sessions.

Frequently Asked Questions
- Are these shocks compatible with my 1/10 scale RC car? — The Fastrax 1/10th 55mm Alloy Adjustable Shocks are engineered to fit a wide range of 1/10 scale platforms including Traxxas, ARRMA, Losi, HPI, Tamiya, Team Associated, Axial Racing, Mugen and Element Enduro models. However, we recommend checking your vehicle's specifications or consulting with our team at RC Model Shop to confirm compatibility with your specific chassis before ordering, as some models may have unique suspension geometry requirements.
- Do I need shock oil to use these shocks? — Yes, these adjustable shocks require shock oil to function properly. You will need to purchase oil separately and fill the shocks to your preferred viscosity level, which allows you to fine-tune your suspension dampening for your specific driving conditions and racing style. Different oil viscosities will affect how your suspension responds to bumps and turns.
- What makes adjustable shocks better than standard shocks? — Adjustable shocks give you precise control over your vehicle's suspension characteristics, allowing you to modify dampening rates, ride height, and overall suspension behaviour without replacing the entire shock assembly. This tuning capability means you can adapt your suspension for different tracks, weather conditions, and driving styles, which leads to improved handling, better traction, and faster lap times in competitive racing scenarios.
- Are these suitable for beginners? — Whilst these shocks are quality components, they are best suited to RC enthusiasts who have some experience with vehicle assembly and suspension tuning. Beginners should ensure they understand how to properly fill and assemble shocks before purchasing. However, the Fastrax brand is known for producing reliable, user-friendly products, and our team at RC Model Shop can provide guidance on installation and setup to help you get the most from your purchase.
- What is the difference between 55mm and 75mm shocks? — The primary difference is length, which affects the suspension geometry and ride height of your RC car. The 55mm shocks are designed for vehicles that require a shorter shock length, whilst the 75mm variant offers greater suspension travel. Your vehicle's chassis design will determine which length is appropriate, so always verify compatibility before ordering.
- Why does the spring retainer require careful fitting? — Some users have noted that the spring retainer can be fiddly to fit, which is common with quality adjustable shocks. Taking time to carefully align and secure the spring retainer ensures proper shock assembly and prevents damage to components. A small flathead screwdriver and patience will help with installation.
