Overview
The Traxxas Suspension pins, lower, inner (Front or Rear), 4x64mm (2 pcs) in hardened steel (TRX8941) represent a premium upgrade for serious RC enthusiasts in the UK who demand maximum strength and durability from their suspension components. Whether you're running a Traxxas Maxx, Maxx Slash, or WideMaxx monster truck, these hardened steel pins are engineered to withstand the extreme forces generated during aggressive driving and high-impact landings. If you're the type of RC driver who likes to go big, bash hard, and push your vehicle to its limits, this upgrade delivers the reliability you need without breaking the bank—it's an investment under £30 that can be installed in approximately 30 minutes.
Stock screw-in suspension pins can back out over time with heavy use, potentially causing suspension failure at the worst possible moment. These genuine Traxxas hardened steel pins eliminate that risk entirely by using a captured design with button-head screws and retaining caps, ensuring your pins stay exactly where they belong no matter how hard you drive. The extra-strong steel construction resists bending far better than standard pins, giving you the confidence to attack any terrain, jump any obstacle, and explore the limits of your RC car without worrying about suspension integrity. This is an essential upgrade for RC car UK enthusiasts who take their bashing seriously.
Beyond raw strength, Traxxas engineers have designed these pins with precision fit tolerances and a low-friction finish that allows your suspension to operate as freely as possible. This means you're not sacrificing responsiveness or handling characteristics in exchange for durability—you get both. The installation process is straightforward, and Traxxas even provides a metric scale printed right on the instruction sheet to help you identify pin lengths, eliminating guesswork and ensuring you use the correct pin for each suspension location.
Key Features
- Hardened Steel Construction — The pins are manufactured from premium hardened steel that resists bending and deformation under the extreme suspension forces generated during aggressive driving, jumping, and high-impact landings, giving you superior durability compared to standard pins.
- Captured Design with Retaining Caps — Unlike stock screw-in pins that can back out over time, these pins are captured by button-head screws and retaining caps, ensuring they remain securely in place throughout extended driving sessions and preventing suspension failure caused by loose hardware.
- Precision Fit and Low-Friction Finish — Each pin is engineered with tight tolerances and treated with a low-friction surface treatment that allows your suspension to articulate freely and respond instantly to terrain changes, maintaining the handling characteristics your Maxx or WideMaxx was designed for.
- Front and Rear Compatibility — These pins work as both front and rear lower inner suspension pins, providing complete coverage for your truck's suspension system in a single purchase, simplifying the upgrade process and reducing the number of spare parts you need to keep on hand.
- Perfect for WideMaxx Upgrades — If you've installed a WideMaxx kit on your Maxx, this upgrade is especially valuable because the longer arms in the WideMaxx kit apply additional leverage and stress to the suspension pins, making hardened steel pins an essential companion upgrade for maximum reliability.
- Quick Installation — Most drivers can complete the installation in approximately 30 minutes without specialist tools or technical knowledge, making this one of the quickest suspension upgrades you can perform to dramatically improve durability.
- Metric Scale Included — The instruction sheet features a printed metric scale and an actual-size pin identification guide, allowing you to quickly and accurately identify which pin length belongs in each suspension location without measuring tools or guesswork.
Technical Performance
These hardened steel suspension pins represent a significant step up in suspension performance and reliability compared to the factory screw-in pins found on stock Traxxas Maxx and WideMaxx trucks. The 4x64mm dimensions provide the correct fitment for the lower inner suspension positions on both front and rear suspension assemblies. The hardened steel material offers substantially greater resistance to bending and permanent deformation than standard steel or softer alternatives, which is critical because suspension pins experience tremendous shear and bending forces during aggressive driving. When you land a big jump with your brushless RC monster truck or navigate rough terrain at full speed, the suspension compresses and extends rapidly, placing immense stress on every pin in the system. Standard pins can gradually bend under this repeated stress, eventually leading to suspension geometry changes, handling issues, or complete pin failure. The Traxxas hardened steel pins eliminate this problem through superior material selection and heat treatment. The captured design using button-head screws and retaining caps is far more secure than the traditional screw-in method, which relies on the pin threads remaining tight—something that becomes increasingly difficult with vibration and repeated use. This design approach is proven in high-performance RC racing environments and competition-grade vehicles. The precision fit ensures minimal play or looseness in the suspension arms, critical for maintaining accurate suspension geometry and predictable handling. The low-friction finish reduces binding and allows smooth articulation throughout the full range of suspension travel, ensuring your truck's suspension performs exactly as the engineers at Traxxas intended.

Frequently Asked Questions
- Are these pins suitable for my Traxxas Maxx or WideMaxx monster truck? — Yes, these TRX8941 pins are specifically engineered for the Traxxas Maxx and WideMaxx models, providing a direct replacement for the factory screw-in pins on both vehicles. They are compatible with all Maxx Slash variants including red, green, rock and roll, and blue colour options, as well as all WideMaxx monster truck versions.
- How much better are hardened steel pins compared to stock pins? — Stock screw-in pins can back out over time due to vibration, potentially causing suspension failure. Hardened steel pins resist bending far better than standard alternatives and use a captured design with retaining caps that prevents backing out entirely. The extra-strong steel resists deformation even during extreme driving, and the precision fit allows unrestricted suspension movement.
- Will these pins affect my truck's handling or suspension response? — No, these pins are engineered to maintain your truck's original suspension characteristics. The precision fit tolerances and low-friction finish allow your suspension to articulate freely and respond instantly to terrain, so you sacrifice nothing in terms of handling while gaining significant durability benefits.
- Are these pins difficult to install on my RC car? — Not at all. Most drivers can complete the installation in approximately 30 minutes without specialist tools. Traxxas provides a metric scale printed directly on the instruction sheet, and an actual-size pin identification guide is available, eliminating the need for measuring equipment and making pin identification quick and accurate.
- Why should I upgrade if I don't drive extremely hard? — Even moderate driving generates suspension stress over time. Stock pins can gradually loosen, and hardened steel pins provide peace of mind that your suspension will remain secure and reliable throughout extended driving sessions, preventing unexpected failures and the need for frequent maintenance checks.
- Are these pins essential for my WideMaxx conversion? — If you've installed a WideMaxx kit with longer suspension arms, hardened steel pins are especially recommended because the increased arm length applies additional leverage and stress to the pins. This makes them a smart companion upgrade that ensures your suspension remains reliable despite the extra demands placed on it.
