Overview
The ARRMA Hinge Pin Front Upper 4x46mm is an essential suspension component for RC enthusiasts across the UK who demand reliability and performance from their models. Whether you're a seasoned competitor running brushless RC trucks or a weekend basher exploring the world of ready-to-run RC cars, having quality spare parts in your RC toolbox is crucial for maintaining peak performance. These super-tough hinge pins are engineered to withstand the demanding forces of high-speed RC driving, making them the perfect replacement component for your ARRMA 1/7 and 1/8 scale models.
Hinge pins are critical suspension components that allow your RC vehicle's suspension arms to articulate and flex during driving. When these components wear or break during aggressive driving or competition, having genuine ARRMA replacement parts ensures your RC car maintains its factory geometry and handling characteristics. This two-pack offers excellent value, allowing you to keep spare pins ready for quick field repairs or routine maintenance. For RC enthusiasts in the UK who refuse to compromise on quality, ARRMA's engineering excellence is reflected in every component they produce.
RC Model Shop stocks these genuine ARRMA parts because we understand that serious hobbyists need access to authentic, manufacturer-approved components that deliver consistent performance. Whether you're upgrading your suspension geometry, replacing worn pins from intensive use, or simply building your spare parts inventory, these hinge pins represent the foundation of a well-maintained RC setup.
Key Features
- Super-strong steel material — Manufactured from high-quality steel that provides exceptional durability and longevity, resisting bending and breaking even under the extreme stresses of aggressive cornering, jumps and competitive racing where lighter plastic alternatives would fail.
- M4 x 46mm specification — The precise metric dimensions ensure perfect fitment and compatibility with your ARRMA suspension components, maintaining factory geometry and suspension performance without modification or adapter parts.
- Two-pack quantity — Each package includes two hinge pins, allowing you to replace both sides of your vehicle's front suspension or maintain spare components for quick track-side repairs during competitions and events.
- Genuine ARRMA manufacturer part — These pins are official ARRMA components designed and tested specifically for their models, guaranteeing compatibility and performance standards that aftermarket alternatives simply cannot match.
- Ideal spare part investment — Building a comprehensive spare parts collection is fundamental to RC car maintenance, and these hinge pins represent an affordable way to keep your suspension systems ready for action.
Technical Performance
Hinge pins represent one of the most critical yet often overlooked components in RC suspension systems. These small but mighty components serve as the pivot points that allow your suspension arms to move freely, absorbing impacts and maintaining consistent tyre contact during aggressive driving. The M4 x 46mm specification delivers the optimal balance of strength and articulation for ARRMA's 1/7 and 1/8 scale models, which are engineered to deliver impressive performance whether you're running them as ready-to-run RTR machines or competition-grade platforms. The steel construction ensures that even under the extreme forces generated by brushless motors, high-speed cornering, and aggressive jumps, these pins maintain their structural integrity. ARRMA's engineering expertise means that every dimension, from the 4mm shaft diameter to the 46mm length, has been carefully calculated to work harmoniously with their suspension geometry. The inclusion of two pins per package reflects the reality that serious RC enthusiasts maintain multiple vehicles and appreciate having spares ready to minimise downtime. For those running brushless RC monster trucks, buggies, and street-bash platforms, suspension reliability directly translates to consistent lap times and extended vehicle lifespan.

Frequently Asked Questions
- What ARRMA models are these hinge pins compatible with? — These M4 x 46mm front upper hinge pins are designed for a wide range of ARRMA 1/7 and 1/8 scale models including the LIMITLESS 120 8S, BIG ROCK 6S, FELONY 6S, FIRETEAM 6S, INFRACTION 6S, KRATON 6S, NOTORIOUS 6S, OUTCAST 6S, TALION 6S, TYPHON 6S, MOJAVE 6S and many other models in the ARRMA lineup. Check the manufacturer compatibility list to confirm fitment with your specific model.
- Why do I need spare hinge pins for my RC car? — Hinge pins experience constant stress as they pivot and articulate during driving, particularly during aggressive cornering, jumps and high-speed manoeuvres. Over time, they can wear, bend or break, especially in competitive racing environments. Having genuine spare pins in your toolbox means you can make quick track-side repairs without waiting for shipping, keeping your RC hobby active and enjoyable.
- Are these suitable for beginners with ready-to-run RC cars? — While hinge pin replacement is a relatively straightforward maintenance task, it does require basic mechanical knowledge and tools. Beginners who are just discovering RC cars through ready-to-run models may want to consult their user manual or watch installation guides before attempting suspension work. However, having spare pins available is smart maintenance planning for any RC enthusiast regardless of experience level.
- What tools do I need to install these hinge pins? — Hinge pin installation typically requires a pin puller or drift tool to remove the old pins, along with hand tools to disassemble the suspension arms. The exact tools needed may vary by model, so consulting your ARRMA vehicle manual or installation guides is recommended before beginning.
- How often should I replace my hinge pins? — The lifespan of hinge pins depends on driving intensity, track conditions and maintenance practices. Recreational bashers might replace them annually or as-needed, whilst competitive racers may change them more frequently or inspect them regularly for wear. Hard-packed desert driving, rocky terrain and competition use typically require more frequent inspection and replacement than casual on-road driving.
