Overview
The ARRMA Servo Saver O-Ring Set (ARA340170) is an essential replacement parts kit for owners of ARRMA 1/5 scale brushless RC trucks and stunt vehicles. Whether you're running an ARRMA Kraton 8S, Outcast 8S, or other compatible models, these premium-quality O-rings are precision-engineered to maintain the integrity of your servo saver assembly. As a UK RC enthusiast, you'll appreciate having reliable spare parts on hand to keep your brushless RC truck performing at its best without costly downtime.
Servo savers are critical safety components in high-performance RC vehicles. They protect your expensive servo from damage by allowing controlled flex in the steering linkage during hard impacts and extreme driving conditions. Over time, the O-rings that seal and secure your servo saver assembly can wear out, crack, or lose their elasticity. When this happens, you need genuine replacement parts that match the original specifications of your ready-to-run RC model. This is where the ARRMA Servo Saver O-Ring Set becomes invaluable.
ARRMA is a recognised leader in producing durable, high-performance RC cars and trucks, and their genuine spare parts maintain the same quality standards as their vehicles. By choosing this official ARRMA parts kit, you're ensuring your servo saver continues to function correctly, protecting your servo from damage during aggressive driving, jumps, and rough terrain. For anyone serious about maintaining their brushless RC speed truck or stunt vehicle, this O-ring replacement set is an inexpensive insurance policy against servo damage.
Key Features
- Durable Premium-Quality Rubber — These O-rings are manufactured from high-grade rubber compound specifically formulated to withstand the demands of high-performance RC driving, ensuring long-lasting performance through countless driving sessions without degradation.
- Precision Manufactured for Fast Fit — Each O-ring is precision-engineered to exact dimensions, ensuring they fit perfectly into your servo saver assembly without forcing, cutting installation time and reducing the risk of damage during servicing.
- Easy Servicing — The simple O-ring replacement design means you can quickly swap worn components without specialised tools or technical knowledge, making routine maintenance accessible to all skill levels.
- Two Different Sizes Included — The kit includes two different diameter O-rings (23.4mm and 28.4mm inside diameter), allowing you to replace all O-rings in your servo saver assembly with a single purchase.
- Genuine ARRMA Parts — These are official manufacturer components, guaranteeing compatibility and performance standards that match your original equipment.
- Cost-Effective Maintenance — Replacing worn O-rings is far more economical than replacing an entire servo or servo saver assembly, extending the life of your RC investment.
Technical Performance
The ARRMA Servo Saver O-Ring Set represents proper engineering for RC servo saver assemblies. Each O-ring is manufactured to precise tolerances that ensure reliable sealing and consistent performance across the full range of driving conditions you'll encounter with your 1/5 scale brushless RC truck. The smaller O-rings (23.4mm inside diameter with 1.5mm thickness) and larger O-rings (28.4mm inside diameter with 1.5mm thickness) work together to create a robust sealing system that prevents dust, debris, and moisture ingress whilst maintaining the flexibility needed for the servo saver to function correctly. The premium rubber compound used throughout maintains its elasticity across temperature ranges and resists the effects of UV exposure, oils, and fuel residue. This is particularly important for serious RC enthusiasts who bash their vehicles regularly or compete in high-speed events where servo saver reliability is non-negotiable. The precision manufacturing ensures zero play or gaps when properly installed, maintaining the tight tolerances necessary for accurate steering response and consistent servo operation. Whether you're upgrading worn original parts or stocking spares for frequent maintenance, these O-rings provide the engineering quality expected from genuine ARRMA components.

Frequently Asked Questions
- Which ARRMA models is this servo saver O-ring set compatible with? — This genuine ARRMA part is compatible with the ARRMA 1/5 Kraton 8S 4X4 RTR Brushless Speed Truck (Green), ARRMA 1/5 Kraton 8S EXB 4X4 Roller Brushless Speed Truck (Black), ARRMA 1/5 Kraton 8S EXB AVC 4X4 RTR Brushless Speed Truck (Black), ARRMA 1/5 Outcast 8S AVC 4X4 RTR Brushless Stunt Truck (Red), ARRMA 1/5 Outcast 8S EXB 4X4 Roller Brushless Stunt Truck (Black), and ARRMA 1/5 Outcast 8S EXB AVC 4X4 RTR Brushless Stunt Truck (Black). Always verify your specific model before ordering.
- When should I replace the servo saver O-rings on my ARRMA RC truck? — You should inspect and replace servo saver O-rings whenever you notice reduced steering response, visible cracks or discolouration in the rubber, loss of sealing, or if your servo saver assembly has been subjected to heavy impacts. Regular maintenance intervals typically involve checking O-ring condition during routine vehicle servicing, especially if you bash frequently or drive in dusty conditions.
- What is the purpose of a servo saver and why do the O-rings matter? — A servo saver is a mechanical component that protects your RC servo from damage by allowing controlled flex and movement in the steering linkage. The O-rings within this assembly create seals and maintain proper tension. When O-rings wear out, they lose their elasticity, fail to seal correctly, and can allow the servo saver assembly to become loose, reducing steering precision and potentially allowing damage to occur during impacts.
- Is this suitable for beginners to install? — Yes, absolutely. Servo saver O-ring replacement is one of the simplest maintenance tasks in RC vehicle ownership. No special tools are required beyond basic screwdrivers, and the straightforward design makes installation accessible to beginners. However, if you've never serviced your servo saver before, consulting your ARRMA instruction manual or watching a servicing video is recommended.
- Do I need any special tools to replace these O-rings? — No special tools are needed. You'll only require basic hand tools like screwdrivers to disassemble and reassemble your servo saver assembly. The O-rings themselves install by hand with gentle pressure once the assembly is open.
- What is the difference between the two O-ring sizes included? — The smaller O-rings (23.4 x 1.5mm) and larger O-rings (28.4 x 1.5mm) fit different positions within the servo saver assembly. Both sets function together to create a complete sealing system. The kit includes two of each size to ensure you have spares or can service multiple areas of your servo saver assembly.
