Servo Saver (25T) - Compatible w/ Arrma Mini's

Function & Usage

Servo Saver designed to protect the steering servo by absorbing impacts transferred through the steering system while improving steering response and reliability. Direct replacement upgrade for the factory servo saver (ARA-3442, ARA340203, ARA340203V2).

Upgrade Advantages

Machined from lightweight, high-strength 7075-T6 aluminum alloy for improved durability, rigidity, and resistance to wear compared to the stock component. Features an integrated spring-loaded design that helps absorb sudden steering impacts, reducing stress transferred to the servo gears and improving overall steering system protection. The updated 25T spline design provides a secure connection for compatible servos while maintaining accurate steering input and consistent performance during aggressive driving.

The servo saver features a 25T spline with an approximately 4.9mm diameter. For ARRMA Mini Kraton, ARRMA Grom series models, and LOSI 1/12 NASCAR models using the SPMSSX110 and SPMSSX114 servos, use the compatible 20T version instead. When installing with third-party servos, use the included 2.3x5mm black round-head Phillips screw to secure the servo horn. Pre-assembled for easier installation. Recommended to use medium-strength threadlocker to prevent loosening during use.
