Servo saver for Mini Kraton and Grom

This aftermarket 21T servo saver is a scale RC steering component intended for ARRMA Mini Kraton and related small-scale Grom series models. Machined from 7075 aluminum, the part aims to add durability where stock plastic components are prone to wear.

The assembly includes a built-in spring to absorb impacts and reduce shock transfer to the steering gear, and the spline is a 21T design compatible with the listed models. All supplied hardware arrives pre-assembled, and a medium-strength threadlocker is recommended on metal-to-metal screws to keep fasteners secure during running.

What does the 21T designation mean for compatibility?

21T refers to the spline count on the saver, matching servos and steering hubs that accept a 21-tooth spline, check your servo output spline before fitting.

Is the part ready to install out of the box?

The supplied components are pre-assembled, but apply a medium-strength threadlocker to metal screws where indicated to prevent loosening during use.

What is the intended benefit of this aluminum saver?

It replaces softer stock parts to improve wear resistance and uses an internal spring to help absorb shocks, aiming to protect the steering gear during impacts.
