Precision 21T saver for Mini Kraton and Grom line

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 unit features an internal spring to absorb impacts and limit shock transfer to steering components. Its 21-tooth spline matches servos and hubs designed for that standard, and the hardware is supplied pre-assembled; use a medium-strength threadlocker on metal screws where advised to secure fasteners during operation.

Will this saver fit other small-scale ARRMA steering setups?

It is intended for the Mini Kraton and related Grom series that accept a 21T spline. Verify your vehicle's steering hub and servo spline specification before purchasing to ensure compatibility.

Are modifications needed to fit LOSI 1/12 models?

Most LOSI 1/12 on-road cars listed are compatible with a 21T saver; check that the mounting and spline interface match. Some setups may require minimal trimming or an adapter if non-standard parts are present.

What fasteners should I check after installation?

Confirm all supplied screws are tight and reapply a medium-strength threadlocker to metal-to-metal fixings where the instructions advise to prevent loosening under vibration.
