Technical Performance
The Losi Aluminium Servo Arm 23T represents engineering excellence in servo horn design, utilising premium aluminium material that provides superior strength-to-weight characteristics essential for modern 1/10 scale RC buggies and short course trucks. The 23-tooth spline interface ensures precise mechanical engagement with your servo motor, eliminating the play and slop that can develop in plastic servo arms over time. This component is specifically engineered for the Losi RZR Rey 4WD Brushless platform, which delivers substantial power through a brushless motor system that generates considerable torque through the drivetrain and steering linkage. By upgrading to an aluminium servo arm, you're investing in a part that will maintain consistent steering response and precision lap after lap, crucial for competitive racing where milliseconds matter and reliability cannot be compromised. The fixed servo horn configuration works in harmony with the precision steering geometry of the Baja Rey platform, ensuring your servo inputs translate directly into accurate vehicle response without delay or inconsistency.

Frequently Asked Questions
- Is this servo arm compatible with my Losi Baja Rey RC buggy? — Yes, this 23-tooth aluminium servo arm is specifically designed for and compatible with both the Losi 1/10 RZR Rey 4WD Brushless RTR in Fox edition and the Polaris edition. Always verify your model number before purchasing to ensure compatibility with your specific Losi vehicle.
- Why should I upgrade to an aluminium servo horn instead of using plastic? — Aluminium servo arms offer significantly greater durability, fatigue resistance and longevity compared to plastic alternatives. They maintain their precision geometry better over extended use, resist cracking and breaking under high-torque loads, and provide superior performance consistency for competitive racing or demanding bashing sessions. The weight savings also mean reduced unsprung mass in the steering system.
- What is a 23-tooth servo spline and why does it matter? — The 23-tooth spline refers to the gear teeth that engage with your servo motor's output shaft. This specific tooth count is engineered for the Losi RZR Rey platform to provide optimal mechanical advantage and steering response characteristics. Using the correct tooth count ensures precise fit, eliminates play, and maintains the steering geometry your vehicle was designed around.
- Can I use this servo arm with a servo saver? — Yes, this servo arm is designed for compatibility with both fixed mounting systems and servo saver setups. This flexibility allows you to choose your preferred steering configuration based on your driving style, track conditions and whether you prioritise direct feedback or impact protection for your servo motor.
- What should I do if my current servo arm is damaged? — If your existing plastic or aluminium servo horn has cracked, bent or stripped its spline teeth, replacement is straightforward. Simply disconnect your servo linkage, remove the fastener holding the damaged arm, slide off the old component, install this new Losi aluminium servo arm, and reconnect your steering linkage. No special tools or adjustments are required for proper fitment.
- Is this part suitable for beginners? — Whilst this is a straightforward replacement component that any RC enthusiast can install, it is typically purchased as a replacement part for users already running a Losi Baja Rey 4WD buggy rather than as an entry-level upgrade. If you're new to RC and own a Losi Baja Rey, upgrading to an aluminium servo arm when needed will improve your vehicle's durability and performance.
