Compact aluminium saver for Mini Kraton and related Grom models

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.

An internal spring cushions impact loads to limit shock transmission into the steering servo, and the 21-tooth spline matches servos and hubs designed for that profile. Hardware comes pre-installed; use a medium-strength threadlocker on metal screws where specified to maintain secure assembly during use.

How does 7075 aluminum compare to the stock plastic saver?

7075 aluminum has significantly higher wear resistance than typical plastics used for stock savers, which reduces deformation and extends service life under repeated impacts.

Does the spring wear out quickly?

The internal spring is standard duty for absorbing shocks; with normal running it should remain effective long term, but inspect periodically for fatigue after heavy impacts or prolonged use.

Can the metal spline damage my servo?

If your servo and hub are designed for a 21T metal spline, the fit is normal. Ensure correct installation and that any sharp burrs are removed to avoid accelerated wear on mating parts.
