7075 alloy servo bracket plus 25-tooth sprung horn for Mojave 4S

This upgrade part is built for ARRMA vehicles, replacing the original plastic servo mount and horn with a 7075 aluminium assembly for greater rigidity and easier servicing. The kit makes use of 7075 where noted to stiffen critical areas and ships with a fitted 25T servo horn along with a 23T servo saver steering tube for alternate use.

The sprung servo horn reduces shock transmitted to the servo output and lowers peak load during severe impacts typical in off-road running. Screws are supplied dry so you can position the 23T steering tube as required before applying threadlocker; use threadlocker after final assembly to secure hardware.

Installation notes: verify the servo spline matches the supplied horn and use the provided grade 12.9 screws plus stainless shims to set preload and alignment. This component helps with chassis setup and tuning by simplifying servo removal while keeping steering geometry consistent.

Use this 7075 mount and horn when replacing plastic steering parts on supported ARRMA models; assemble supplied parts, secure with threadlocker after final checks, and confirm spline and alignment during setup.

How should I set preload and alignment with this mount?

Use the supplied stainless shims and grade 12.9 screws to fine-tune preload; adjust until steering is free of binding and then lock fasteners with threadlocker.

Will the sprung horn reduce peak current draw?

The spring lowers instantaneous torque spikes on the servo output which can reduce stress on the servo and may help limit brief current surges under impact.

Is this package suited to heavy jump use?

Yes. The 7075 construction adds stiffness and the sprung horn helps absorb hard landings, but always check fasteners and alignment after heavy runs.

What fasteners are supplied with the kit?

The kit includes grade 12.9 screws in the specified sizes and stainless steel shims to set proper preload and alignment.

How do I confirm spline compatibility before fitting?

Match the spline count on your servo to the supplied 25T horn; if your servo uses a different spline, install the 23T steering tube if compatible or source the correct horn.
