Robust aluminium 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.

Designed to reduce shock transfer with an integrated spring, the saver uses a 21T spline to match compatible servos and hubs. The item ships pre-assembled; where metal-to-metal screws are used, fit with a medium-strength threadlocker to keep fasteners secure under vibration.

Does swapping to an alloy saver change steering feel?

Yes. Metal savers can make the steering feel firmer and reduce flex compared to plastic parts; the internal spring still allows some give to avoid transmitting all impact to the servo.

Should I alter my servo endpoints after fitting?

Generally endpoints remain the same, but check for full travel and bind after installation and make minor radio trims if the saver changes steering centering or travel.

Is additional maintenance required with aluminum savers?

Inspect mating splines and fasteners regularly for wear and looseness; reapply medium threadlocker to any metal screws if they begin to back out during running.
