Overview
The Traxxas Spring Retainers, Upper & Lower (TRX3768) is an essential suspension maintenance and tuning component designed for RC enthusiasts across the UK who demand precision engineering and reliable performance from their models. This comprehensive spring retainer and piston head set provides everything you need to maintain, repair, or fine-tune your Traxxas RC car's suspension system. Whether you're a dedicated weekend basher enjoying your brushless RC car in the park, a competitive racer pushing your vehicle to its limits, or simply someone who values keeping their RC hobby equipment in peak condition, this genuine Traxxas spare part delivers the quality and compatibility you expect from the brand.
Suspension components are critical to the overall performance, handling characteristics, and longevity of your RC model. The spring retainers hold your shock springs securely in place, whilst the piston heads work in conjunction with shock fluid and springs to manage suspension travel and damping. Over time, through regular use, these components may wear, become damaged, or need adjustment to suit different track conditions or driving styles. Having genuine replacement parts on hand ensures you can quickly restore your vehicle to factory specifications or customise your suspension setup with confidence.
This Traxxas part is compatible with a wide range of popular Traxxas models, including the Mini Maxx BL-2S, Mini Rally VXL Ford RS200, Mini Slash BL-2S 4X4, Slash Ultimate 4x4 VXL, Slash VXL, Slash HD XL-5, Stampede 4X4 HD VXL, and many more beloved RC trucks and buggies available to UK buyers. Whether you own one model or an entire fleet, investing in genuine OEM spare parts like this set ensures reliability and preserves the warranty integrity of your equipment.

Technical Performance
The Traxxas Spring Retainers and Piston Head Set (TRX3768) represents precision engineering designed to support the demanding requirements of modern RC vehicles across the UK market. These components are manufactured to exact tolerances using quality materials that withstand the rigours of repeated shock compression, extension, and the forces generated by high-performance brushless RC cars. The spring retainers serve as mechanical anchors that keep your shock springs properly positioned, preventing lateral movement or separation during aggressive driving, jumps, and impacts that are common when operating 1/10 scale short course trucks, monster trucks, and other competition-grade RC models. The piston heads control the flow of shock fluid through the piston assembly, and the number of holes directly affects the rate of fluid displacement and therefore the damping characteristics of the shock. The inclusion of both 2-hole and 3-hole configurations in this set means you can adjust your suspension response without purchasing additional parts, providing excellent value for money and enabling fine-tuning across different track surfaces, weather conditions, and driving intensities. Whether you're running your RC car on carpet, tarmac, grass, or indoor tracks, having the ability to swap piston head configurations allows you to optimise your setup for maximum grip, stability, and handling response. The quality construction ensures that these parts will maintain their integrity through hundreds of driving sessions, providing reliable suspension performance and consistency in your RC car's handling characteristics.

Frequently Asked Questions
- Which Traxxas models are compatible with the TRX3768 spring retainer set? — This set is compatible with a comprehensive range of Traxxas vehicles including the Mini Maxx BL-2S in multiple colours (black, orange, green, blue), Mini Rally VXL Ford RS200 (standard, grey, red, and blue variants), Mini Slash BL-2S 4X4 RTR Short Course Truck (yellow, orange, pink, green), Slash Ultimate 4x4 VXL 1/10 4WD Brushless Short Course Truck (orange), Slash VXL 1/10 4x4 RTR Short Course Truck (orange, red, green, blue), Slash HD XL-5 1/10 2WD RTR Short Course Truck (green, red, blue, orange), and Stampede 4X4 HD VXL 1/10 4WD RTR Brushless Electric Monster Truck (green, blue, orange). If you own any of these models, this set will be directly compatible.
- What is the difference between the 2-hole and 3-hole piston heads? — The number of holes in the piston head affects how much shock fluid can flow through the piston during compression and extension. The 2-hole configuration provides different damping characteristics compared to the 3-hole configuration. By including both options in this set, you can experiment with different setups to find the ideal suspension feel for your driving style, track conditions, or competitive requirements. More holes generally allow for faster fluid flow and potentially softer suspension feel.
- Do I need special tools to install these spring retainers and piston heads? — Whilst specific tool requirements are not detailed in the product information, shock assembly and disassembly typically requires basic RC tools such as shock wrenches or hex drivers. We recommend consulting your vehicle's official Traxxas manual for detailed installation instructions specific to your model.
- How often should I replace these components? — Spring retainers and piston heads are durable components, but they may require replacement if damaged or worn after extensive use. Regular inspection during routine maintenance is recommended. If you notice leaking shock fluid, inconsistent suspension response, or visible damage to the retainers or piston heads, replacement may be necessary to restore optimal performance.
- Why would I want to adjust my piston head configuration? — Adjusting your piston head configuration is a key tuning method in RC racing and serious bashing. Different track surfaces, weather conditions, and driving styles benefit from different damping characteristics. The flexibility to switch between 2-hole and 3-hole configurations without purchasing additional parts makes this set excellent value for any serious Traxxas enthusiast who wants to optimise their vehicle's handling across varying conditions.
- Are these genuine Traxxas parts? — Yes, this is an official Traxxas OEM (original equipment manufacturer) part, part number TRX3768, manufactured to exact Traxxas specifications. Genuine parts ensure perfect fitment and durability compared to aftermarket alternatives.
