Overview
The ARRMA Shock Mount Pin 3x21.5mm Black (4) is an essential suspension spare part for RC car enthusiasts across the UK. Whether you're a dedicated basher, a weekend racer, or someone who runs brushless 4WD RC trucks and buggies, shock mount pins are components you'll need to replace periodically as part of routine maintenance and repairs. These precision-engineered pins connect the shock absorber to the chassis and suspension arms, making them critical to the handling and performance of your ready-to-run RC vehicle. When you invest in a high-performance brushless RC car like an ARRMA model, having genuine replacement parts on hand ensures you can keep your machine running at peak performance without extended downtime.
This pack contains four shock mount pins, giving you multiple spares to carry in your RC tool box. The pins measure 3mm in diameter and 21.5mm in length, and they are manufactured from super-tough steel that resists bending, breaking and wear even under the demanding conditions of aggressive driving. ARRMA is renowned for producing durable, high-quality RC vehicles and components, and these shock mount pins reflect that same engineering excellence. They are compatible with a wide range of ARRMA models, from 1/7 scale street bash trucks like the Infraction and Limitless, to 1/8 scale buggies and trucks such as the Typhon, Kraton, Outcast and Talion, making them a versatile spare part for any ARRMA RC car UK collection.
If you own an ARRMA RC model or are considering purchasing one of these premium ready-to-run RC vehicles, stocking replacement shock mount pins is a smart investment. Suspension maintenance is part of responsible RC ownership, and having genuine ARRMA parts ensures compatibility, durability and peace of mind. These shock pins are precision-manufactured to exacting standards, so they fit and remove consistently every time, whether you're performing routine maintenance or making suspension adjustments to suit your driving style or track conditions.
Key Features
- Super-tough steel construction — Made from high-quality steel that delivers long-lasting durability and resists bending or damage during intense RC driving sessions, whether you're street bashing a 1/7 scale truck or racing a 1/8 buggy on challenging terrain.
- Precision manufactured — Each pin is engineered to exact tolerances, ensuring consistent and reliable fitting and removal every time you service your shock absorbers, with no wobbling or loose tolerances that could affect suspension geometry.
- Pack of four pins — Includes four shock mount pins per pack, giving you multiple spares to keep in your RC tool box so you always have replacements available for both front and rear suspension, or for backup when performing maintenance on multiple vehicles.
- 3x21.5mm dimensions — The specific 3mm diameter and 21.5mm length are designed to fit ARRMA suspension systems perfectly, ensuring proper shock mounting and alignment for optimal suspension performance.
- Compatible with multiple ARRMA models — Works with numerous ARRMA RC cars including 1/7 scale models like the Felony, Infraction, Limitless and Mojave, as well as 1/8 scale models including the Kraton, Notorious, Outcast, Talion and Typhon, making this a versatile spare part for ARRMA enthusiasts.
Technical Performance
The shock mount pin is a fundamental component of RC vehicle suspension systems, and quality matters significantly. These ARRMA pins are manufactured from super-tough steel rather than cheaper alternatives like aluminium or plastic, which means they resist bending and maintain dimensional accuracy even when subjected to repeated impacts and vibration from aggressive driving. The 3mm diameter provides adequate structural strength while remaining lightweight enough not to add unnecessary weight to the suspension assembly. At 21.5mm in length, the pins are designed to span the distance between the shock body and the chassis mounting points on ARRMA models, maintaining proper suspension geometry and ride height. The precision manufacturing process ensures that each pin meets exact specifications, so when you install them in your RC car, there are no gaps, play or inconsistency that could degrade handling. Whether you're running a fast 1/7 street bash truck like the Infraction 6S with brushless power, a 1/8 scale speed truck like the Talion, or a full-size buggy like the Typhon, the suspension system relies on these pins to keep everything properly aligned and responsive. Regular replacement of worn shock mount pins is part of standard RC maintenance, especially if you bash hard or race frequently, as wear and impact damage can accumulate over time and affect suspension performance.

Frequently Asked Questions
- What is a shock mount pin and why do I need spares? — Shock mount pins are small but essential components that secure the shock absorber to the chassis and suspension arms of your RC car. They experience significant stress during driving and can bend, wear or break, especially if you bash hard or race regularly. Having spare pins allows you to quickly repair your RC vehicle and get back to driving without waiting for replacement parts to arrive.
- Will these pins fit my ARRMA RC car? — Yes, these 3x21.5mm shock mount pins are compatible with numerous ARRMA models including 1/7 scale vehicles such as the Felony 6S AVC, Infraction 6S, Limitless 6S and Mojave 6S, as well as 1/8 scale models including the Kraton 6S, Notorious 6S, Outcast 6S, Talion 6S and Typhon 6S in both standard and TLR Tuned variants. Verify your specific model against the compatibility list to confirm fitment.
- Are these original ARRMA parts? — Yes, these are genuine ARRMA parts manufactured to OEM specifications, ensuring they meet the same quality and durability standards as the parts supplied with new ARRMA ready-to-run RC vehicles. Purchasing genuine parts guarantees compatibility and reliability.
- How often do I need to replace shock mount pins? — The frequency depends on how heavily you use your RC car. Casual weekend bashers might go many months between replacements, whilst competitive racers or aggressive drivers may need to replace pins every few months. Inspect your pins regularly for signs of bending or damage, and replace them if they no longer sit flush or if they show visible wear.
- Can I use aftermarket pins instead of ARRMA genuine parts? — Whilst some aftermarket pins may fit, genuine ARRMA parts are precision-engineered for your specific vehicle and guarantee proper fit, finish and durability. Using original parts ensures your suspension geometry remains correct and your RC car performs as designed.
- What tools do I need to replace shock mount pins? — You will need basic tools such as a small hex wrench or Allen key to remove the shock mounting bolts, and possibly a flathead screwdriver to help remove the old pin. The actual pin removal may require gentle leverage, so a small tool or pick can be helpful. Once removed, installation is straightforward — simply insert the new pin and reattach the mounting hardware.
