Overview
The ARRMA Hinge Pin Outer 4x45mm (2) is an essential suspension component designed for serious RC enthusiasts who demand reliability and durability from their spare parts. These super-tough hinge pins are the perfect addition to your RC tool box, whether you're maintaining a high-performance 1/7 scale speed machine, a 1/8 buggy, or any other ARRMA model in your collection. As a leading UK RC hobby retailer, we understand that quality suspension components are critical to maintaining your RC car's performance and longevity, which is why we stock genuine ARRMA parts that meet the exacting standards of the brand.
If you're serious about RC racing or bashing, you'll know that suspension components take a real battering during aggressive driving sessions. The hinge pins that connect your suspension arms are under constant stress, and having high-quality replacements on hand ensures you can get back on the track or trail quickly without compromising performance. Whether you're running a ready to run RC truck, an advanced competition buggy, or anything in between, these genuine ARRMA hinge pins deliver the durability and precision fit you need to keep your suspension working perfectly.
Hinge pins are one of those small but critical parts that can make the difference between a smooth-handling RC car and one with loose, unpredictable suspension geometry. These outer hinge pins measure 4x45mm and come in a convenient pack of two, giving you backup spares when you need them most. Compatible with a massive range of ARRMA models including the 1/7 Limitless, 1/7 Infraction, 1/7 Felony, 1/7 Mojave, 1/8 Kraton, 1/8 Notorious, 1/8 Outcast, 1/8 Talion, and 1/8 Typhon, these hinge pins are a must-have spare for any ARRMA owner in the UK.

Technical Performance
The ARRMA Hinge Pin Outer 4x45mm components are engineered from super-strong steel that delivers the robust performance required in modern RC racing and bashing applications. At 4mm diameter and 45mm length, these outer hinge pins are precisely dimensioned to fit correctly within ARRMA's suspension architecture across their full range of 1/7 and 1/8 scale vehicles. The steel construction provides excellent durability and wear resistance, essential qualities when suspension components are subjected to repeated impacts, aggressive cornering forces, and the demanding conditions experienced during high-speed RC car operation on UK tracks and trails. Unlike plastic alternatives that can degrade over time, steel hinge pins maintain their dimensional stability and structural integrity through countless hours of use, ensuring consistent suspension geometry and predictable handling characteristics. The precision manufacturing ensures a perfect fit with matching suspension components, preventing the looseness and rattling that can develop with inferior quality pins. Whether you're operating a high-powered 8S brushless RC monster truck, a competition-grade 1/8 scale buggy, or a street bash vehicle, these hinge pins provide the reliability and performance you need to keep your RC car handling at its best throughout extended driving sessions and throughout the competitive season.

Frequently Asked Questions
- What are hinge pins and why do I need spares for my ARRMA RC car? — Hinge pins are the critical suspension components that connect your suspension arms to the chassis and allow them to articulate smoothly. During aggressive driving, these pins experience constant stress from impacts, cornering forces, and the general wear and tear of RC operation. Having spare hinge pins on hand means you can quickly replace worn or damaged pins without having to wait for replacement parts to arrive, keeping your RC car on the track or trail. These outer pins specifically connect the outer suspension arms, making them essential spares for anyone running ARRMA vehicles regularly.
- Are these genuine ARRMA parts or aftermarket components? — These are genuine ARRMA parts manufactured to the brand's exacting specifications. The model number AR330194 is the official ARRMA part number, and purchasing genuine components ensures perfect fitment with your ARRMA vehicle and maintains the suspension geometry and performance characteristics that the engineers designed into your specific model. Aftermarket alternatives may cause fitment issues or wear prematurely, whereas genuine ARRMA parts deliver consistent, reliable performance.
- Will these hinge pins fit my ARRMA RC car? — These outer hinge pins are compatible with a comprehensive range of ARRMA models across both 1/7 and 1/8 scales, including the Limitless, Infraction, Felony, Mojave, Kraton, Notorious, Outcast, Talion, and Typhon ranges. Check the detailed compatibility list in our product information to confirm your specific model is supported. The 4x45mm dimensions are the standard specification for outer hinge pins across most current ARRMA vehicles, but we recommend verifying compatibility with your model before ordering.
- How often should I replace my suspension hinge pins? — The lifespan of hinge pins depends on how frequently and aggressively you use your RC car. High-speed bashing, frequent jumps, and rough terrain will wear pins more quickly than casual driving. As part of regular maintenance, inspect hinge pins for visible wear, bending, or looseness during suspension geometry checks. If you notice any damage or excessive wear, replacement is recommended immediately to prevent suspension handling issues. Having spare pins like this 2-pack on hand means you can perform maintenance without delays.
- Is the steel construction better than plastic alternatives? — Yes, the super-strong steel material used in these ARRMA hinge pins significantly outperforms plastic alternatives in terms of durability, wear resistance, and dimensional stability. Steel maintains its shape and structural integrity through countless hours of use, whereas plastic components can degrade, become brittle, or develop wear that compromises suspension geometry. For serious RC enthusiasts and racers, steel hinge pins are the superior choice that ensures consistent, reliable performance throughout the season.
- Do I need any tools to install these hinge pins? — Installation of hinge pins typically requires basic tools commonly found in any RC hobbyist's toolkit, such as small pliers or a suspension pin removal tool. The installation process is straightforward and can be completed in just a few minutes. If you're unfamiliar with suspension maintenance, we recommend consulting your ARRMA vehicle's manual for detailed installation instructions or visiting our physical store in Walsall where our experienced team can provide guidance.
