• Straight arm design that makes the servo saver stronger and more direct in steering
• Improved steering precision and a crisper response to steering input
• Ideal upgrade for bashing, track use, and on-road NASCAR driving

Features and benefits

(1) Material and construction
The servo saver is made from high-quality 7075 high-strength aluminum, which is both lightweight and very rigid. This provides:

• Significantly better durability than plastic parts
• Less flex in the steering – more precise control
• Longer lifespan, even under heavy use

The built-in spring helps absorb impacts when you hit obstacles, curbs, or during hard landings. At the same time, the straight arm design provides extra strength and a more direct transfer of power from the servo to the wheels, so the car steers sharper and more controlled.

(2) Improved steering and servo protection
The upgrade improves steering performance by:

• Making the steering more precise and responsive
• Reducing the risk of gear damage in the servo during hard impacts
• Protecting the original servo (SPMSSX110, 20T) from overload

The built-in spring acts as a safety valve: during a hard impact, the servo saver gives slightly, instead of transferring the full force directly into the servo gears. This means fewer broken servos and more run time.
