Servo Saver (20T) - Compatible w/ Arrma Mini's

Function & Usage

Servo Saver designed to protect the steering servo and improve steering response by absorbing impacts transferred through the front steering system. Direct replacement upgrade for the factory 20T 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 factory plastic component. Features an integrated spring-loaded design that helps absorb steering impacts while protecting the servo gears during aggressive driving and crashes. The improved construction helps provide more precise steering input, better steering consistency, and increased reliability under demanding RC conditions.

Designed with a 20T spline and 4.7mm diameter output to fit compatible ARRMA Grom series models and LOSI 1/12 NASCAR vehicles using the SPMSSX110 and SPMSSX114 servos. When installing on the SPMSSX114 servo, the servo saver may fit tightly against the output gear. This ensures proper transmission accuracy; align the spline teeth correctly and press down evenly during installation. Recommended to use medium-strength threadlocker on screws to prevent loosening during use.
