Traxxas Suspension Pin Set Complete Hardened Steel TRX8940X

Overview

The Traxxas Suspension Pin Set (TRX8940X) is a premium upgrade component designed for serious RC enthusiasts in the UK who demand maximum durability and performance from their Traxxas Maxx models. This complete hardened-steel suspension pin set replaces the standard screw-in suspension pins with high-strength alternatives, delivering superior reliability during aggressive driving, jumps, and off-road bashing. Whether you're running a Traxxas Maxx Slash short course truck or the WideMaxx monster truck platform, this suspension upgrade is essential for maintaining consistent performance and reducing maintenance downtime caused by worn or damaged pins.

Built to withstand the extreme forces generated by high-performance 1/8 scale RC vehicles, this hardened-steel pin set represents a significant step up from factory components. The comprehensive kit includes all the pins, fasteners, and retainers needed to upgrade both upper and lower suspension arms, plus steering block kingpins, making it a complete one-stop solution for suspension maintenance and enhancement. RC car UK enthusiasts who participate in competitive racing or regularly enjoy challenging terrain will appreciate the durability and smooth operation this upgrade provides.

Installation is straightforward thanks to the button-head screws and retaining caps system that captures each pin securely without fuss. The low-friction finish of these hardened-steel pins ensures super-smooth suspension articulation, allowing your suspension to respond more efficiently to terrain changes and impacts. This translates directly into better handling, improved traction, and more predictable suspension behaviour whether you're racing on a track or bashing through rough ground.

Key Features

• Hardened Steel Construction — These suspension pins are manufactured from hardened steel rather than softer materials, providing significantly greater strength and durability compared to standard factory pins, which means they withstand repeated impacts, jumps, and aggressive driving without deforming or breaking.
• Low-Friction Finish — The specially finished surface reduces friction between the pin and mounting points, enabling smoother suspension movement that translates into better vehicle control, improved handling characteristics, and more responsive suspension articulation on any terrain.
• Button-Head Screws with Retaining Caps — The secure fastening system using button-head screws and retaining caps prevents pins from becoming loose during driving, eliminating suspension rattle and maintaining consistent geometry even during intense racing or bashing sessions.
• Complete Suspension System Coverage — This kit provides pins for both upper and lower suspension arms plus steering block kingpins, meaning you can upgrade your entire suspension system in one comprehensive purchase rather than buying multiple smaller components.
• Easy Installation — The inclusion of illustrated instructions makes installation straightforward for RC car UK enthusiasts of all experience levels, though experienced modellers will appreciate the quality of the engineering that makes replacement quick and reliable.
• Maximum Strength and Durability — Specifically engineered to provide premium strength characteristics, these pins are designed to outlast standard components and reduce the frequency of suspension maintenance, keeping your RC truck running longer between service intervals.
• Comprehensive Hardware Set — The kit includes 16 inner and outer pins for suspension arms, 4 steering block kingpins, all necessary fasteners (3x8mm and 3x6mm button-head cap screws), and retaining caps, eliminating the need to source additional hardware.
• WideMaxx Kit Compatible — Beyond the standard Maxx Slash range, these pins are also compatible with the Traxxas 8995 WideMaxx upgrade kit, making this an excellent choice for users of that platform as well.

Technical Performance

The Traxxas Suspension Pin Set represents a significant upgrade in suspension reliability and performance for 1/8 scale brushless RC vehicles like the Maxx Slash and WideMaxx monster trucks. The hardened-steel construction is engineered to handle the extreme loads generated by high-performance suspension systems, particularly in vehicles equipped with 6S brushless power that can produce substantial acceleration and impact forces. The material selection ensures that these pins maintain their dimensional accuracy over thousands of suspension cycles, preventing the gradual loosening and wear that characterises inferior aftermarket alternatives or worn factory components. The low-friction finish is achieved through a precision manufacturing process that reduces surface drag, allowing suspension oils and greases to work more effectively whilst minimising binding and stiction in the suspension linkage. This technical attention to detail results in measurably smoother suspension response, which becomes critically apparent when driving over rough terrain, executing rapid direction changes, or landing jumps at speed. For brushless RC bashers and racers in the UK, the improved suspension consistency translates directly into more predictable vehicle behaviour, reduced setup changes needed between driving sessions, and extended intervals between maintenance procedures. The button-head screw fastening system is not merely a convenience feature—it's an engineering solution that prevents vibration loosening and maintains suspension geometry within tight tolerances throughout extended driving sessions.

Frequently Asked Questions

• Is this suspension pin set compatible with my Traxxas RC vehicle? — This suspension pin set is specifically designed for Traxxas Maxx Slash 1/8 4WD brushless short course trucks (available in Red, Green, Rock N Roll, and Blue colour options) and Traxxas WideMaxx monster trucks (Red, Rock N Roll, and Green versions). Check your model number against the compatibility list to confirm—if you own either platform, this is the correct upgrade.
• What is the benefit of upgrading to hardened steel suspension pins? — Factory suspension pins are typically made from softer steel or aluminium to reduce manufacturing costs. Hardened-steel pins offer significantly greater durability, resist deformation from impacts and jumps, maintain their dimensional accuracy over thousands of suspension cycles, and reduce maintenance frequency. For RC car UK enthusiasts who bash regularly or race competitively, this upgrade pays dividends through improved reliability and reduced downtime.
• How difficult is installation of this suspension pin set? — Installation is straightforward and suitable for modellers of varying experience levels. The kit includes illustrated instructions that walk you through the replacement process. The button-head screw and retaining cap system is intuitive, and most users can complete the full suspension upgrade in 30-45 minutes with basic tools.
• Will this suspension pin set improve my vehicle's handling? — Yes, the low-friction finish and precise manufacturing tolerances deliver noticeably smoother suspension articulation compared to worn or inferior components. This improved suspension consistency translates into better vehicle control, more predictable handling characteristics, and enhanced traction over varied terrain.
• What is the difference between the pins included in this kit? — This complete set includes multiple pin lengths (64mm, 47mm, 38mm, 33mm, and 22mm) specifically sized for different suspension mounting points on upper arms, lower arms, and steering blocks. Each length corresponds to specific locations in your suspension geometry, ensuring correct installation and optimal performance.
• Is this suspension kit suitable for beginners? — Absolutely. Whilst suspension upgrades are popular with experienced modellers, this kit is equally suitable for beginners upgrading from stock components. The illustrated instructions and straightforward button-head screw system make installation accessible to anyone, and the upgrade immediately improves suspension smoothness and reliability.
• How long do hardened-steel suspension pins typically last? — Hardened-steel pins engineered to this standard typically outlast standard factory components by several multiples, particularly in terms of dimensional stability and resistance to deformation. With normal bashful driving, you can expect excellent longevity; extreme competitive racing or extremely abusive use may eventually necessitate replacement, but these pins represent a major durability improvement over alternatives.
