Overview
The Losi Aluminum Servo Arm 25T: Baja Rey is a precision-engineered replacement servo horn designed specifically for the Losi 1/10 RZR Rey 4WD Brushless RTR models. Whether you own the Fox variant or the Polaris edition of this popular RC buggy, this servo arm provides a durable, high-performance control linkage for your vehicle's steering system. If you're an RC car enthusiast in the UK looking to upgrade or replace a damaged servo horn, this genuine Losi component offers the reliability and fit quality you need to keep your brushless RC car performing at its best.
Servo horns are critical components in any RC vehicle, as they connect your servo motor to the steering linkage and directly control your buggy's directional response. A worn, bent or damaged servo arm can compromise handling precision and create sloppy steering feel, particularly important if you're enjoying weekend bashing or competitive racing with your ready to run RC. The Losi Aluminum Servo Arm 25T is manufactured to OEM specifications, ensuring perfect compatibility and performance with your Baja Rey platform.
This is an essential spare part for any Losi RZR Rey owner, and a practical upgrade if your original servo arm has sustained impact damage or wear. Keep a spare in your spares box so you're never left sidelined at the track or off the field. At RC Model Shop, we stock genuine Losi parts to keep your brushless RC buggy in peak condition.
Key Features
- Aluminium Construction — Manufactured from lightweight yet rigid aluminium alloy, this servo arm offers superior strength compared to plastic alternatives, resisting bending and cracking under the stresses of off-road driving and high-speed steering inputs.
- 25T Spline Fitment — This servo horn is designed with a 25-tooth spline that fits standard 25T servo outputs, ensuring secure, wobble-free connection to your servo motor and reliable steering control without slippage.
- Fixed Servo Saver Configuration — The fixed design means this arm mounts directly to your servo without a servo saver mechanism, providing direct steering feel and precise control feedback ideal for rock crawling and technical driving where responsiveness matters most.
- Genuine Losi Component — As an OEM Losi part, this servo arm meets the exact specifications and tolerances of your RZR Rey, guaranteeing perfect fitment and eliminating compatibility issues.
- Replacement/Upgrade Part — Perfect for replacing a damaged servo horn or upgrading from the stock component, this part keeps your RC buggy running smoothly and extends the lifespan of your steering system.
Technical Performance
The Losi Aluminum Servo Arm 25T represents careful engineering for durability and performance in the demanding world of 1/10 scale RC buggies. Constructed from quality aluminium rather than plastic, this servo horn is significantly more resistant to the impacts and lateral forces experienced during aggressive off-road driving, especially in brushless RC applications where high-speed steering corrections are frequent and demanding. The 25-tooth spline profile ensures a secure, positive connection to your servo output shaft, eliminating the play or rocking that can develop with worn plastic horns. The fixed configuration — without a servo saver — means your steering input is transmitted directly and immediately to your front wheels, providing the crisp, responsive handling characteristics that Losi drivers expect. This direct linkage is particularly valued in technical RC driving scenarios where precision and feel are paramount. The aluminium construction also offers superior heat dissipation compared to plastic, keeping your servo system running cooler during extended driving sessions.

Frequently Asked Questions
- Will this servo arm fit my Losi 1/10 RZR Rey 4WD Brushless RTR? — Yes, this servo arm is specifically engineered for compatibility with the Losi 1/10 RZR Rey 4WD Brushless RTR, including both the Fox and Polaris editions. The 25T spline profile matches standard servo outputs on these models. Simply verify that your servo uses a 25-tooth spline before ordering.
- Why would I need a replacement servo arm? — Servo arms can wear out, bend or crack through impact damage, age-related stress, or sustained use in harsh off-road conditions. A damaged servo arm causes imprecise steering, uneven front-end response, and can strain your servo motor. Replacing it restores tight, responsive handling and prevents further damage to your steering system.
- What is the difference between this fixed arm and a servo saver arm? — This fixed configuration mounts directly to the servo without a servo saver mechanism, meaning your steering input is delivered immediately and with no compliance. Servo saver arms include a spring or friction element that absorbs impact shocks. Fixed arms provide more direct feel and responsiveness but offer less shock protection, making them ideal for technical driving where control is paramount.
- Is aluminium better than plastic for servo horns? — Yes, aluminium offers superior strength and durability compared to plastic servo horns. Aluminium resists bending under high-speed steering inputs, better withstands crashes and impacts, and provides improved longevity, especially in brushless RC vehicles where servo duty cycles are intense and demanding.
- What tools do I need to fit this servo arm? — Installation typically requires a spline wrench or hex key to remove your old servo arm and secure the new one onto your servo output shaft. A small screwdriver may be needed to adjust linkage rods or steering turnbuckles. Consult your RZR Rey manual for precise installation steps.
