GPM Racing 7075 Alloy 20T Servo Saver for Arrma 1/16 Mini Kraton 3S Dsc 4x4 RTR Brushless Speed Truck (MAKM020TSH)

7075 20T servo saver tailored for ARRMA Mini Kraton and LOSI

This 7075 alloy 20T servo saver is an aftermarket replacement compatible with certain ARRMA 1/16 Mini Kraton and LOSI 1/12 models. CNC-machined from high-strength 7075 aluminium, it keeps mass low while providing stable spline engagement and improved durability. The component features a 20-tooth spline with a 4.7mm diameter to match standard 20T servo outputs.

The saver functions as a shock absorber between the servo output and steering linkage, using a spring to absorb impacts and reduce force transferred to the servo gear. Some SPM servos may fit tightly; align the spline teeth and press down evenly to ensure full mesh before final fitting.

Installation is similar to other small-scale steering replacements: remove the original 20T saver, confirm spline alignment, and press this unit onto the servo shaft until the spline fully seats. Fasteners come pre-assembled and a medium-strength threadlocker is suggested on screws to help prevent vibration loosening.

Intended only for RC model use and not suitable for full-size vehicles.

Will this unit work with the listed LOSI 1/12 race cars?

Yes, provided the vehicle uses a standard 20T, 4.7mm diameter servo output spline as used on the models listed in the compatibility section.

Why might installation feel stiff on some servos?

A tight fit is sometimes by design for accurate tooth engagement. Ensure splines are aligned and press evenly; inspect for any debris or burrs if seating remains difficult.

Is threadlocker necessary on the supplied screws?

Using a medium-strength threadlocker is recommended to prevent screws loosening under vibration, though hardware is supplied pre-assembled for convenience. Write Product Review Please sign in your account before you can write any review. Sign In Close
