7075 Alloy 20T servo saver for small-scale ARRMA & LOSI

This 7075 alloy 20T servo saver is an aftermarket replacement designed for specific 1/16 and 1/12 small-scale ARRMA and LOSI models. Machined from high-tensile 7075 aluminum, it keeps the RC scale steering assembly light while aiming for consistent engagement and durability. The part uses a 20-tooth spline with a 4.7mm diameter to match standard 20T output gears.

Functionally the unit acts as a mechanical buffer between the servo output and the steering linkage, with a built-in spring to absorb impacts and reduce shock transmitted to the servo gear. The design notes a tight fit when paired with certain SPM servos; in those cases align the tooth positions and press down evenly to ensure full mesh before securing.

Installation is straightforward for hobby technicians familiar with small-scale steering systems: remove the factory 20T servo saver, confirm spline alignment, then press the replacement onto the servo shaft until the spline seats. All supplied fasteners are pre-assembled for convenience, and medium-strength threadlocker is recommended on screws to prevent loosening under vibration.

This item is intended solely as an RC-scale accessory for model steering systems and is not suitable for full-size vehicles.

Will this servo saver fit the SPMSSX114 servo without modification?

It is compatible but may fit tightly against the output gear, this is intentional for accurate transmission, align the spline teeth and press down evenly during installation.

What material is used and why does it matter?

The part is machined from 7075 aluminum, chosen for a balance of light weight and tensile strength suitable for small-scale steering components.

Are extra screws included and should I use threadlocker?

Basic fasteners are supplied pre-assembled, and medium-strength threadlocker is recommended to keep screws secure under vibration.
