25kg Metal Gear Waterproof Steering Servo, High Torque RC Car Replacement Servo with Horn

Original price was: $99.00.Current price is: $79.88.

A high-torque metal-gear waterproof steering servo to replace a worn or stripped servo in 1/8 scale RC cars, buggies, and bashers. Metal gears resist stripping under hard steering, the waterproof housing handles wet runs, and it includes a servo horn and mounting hardware; verify voltage and spline count before fitting.

Why it matters

Stripped gears mean loose, vague steering

When the plastic gears inside a stock servo strip, steering goes soft, drifts, or stops responding under hard bashing. A metal-gear replacement holds its position and keeps steering precise instead of grinding itself out.

  • β–ͺΒ Β Stripped plastic gears. Cheap internal gears strip under hard steering and crash loads.
  • β–ͺΒ Β Vague or wandering steering. A worn servo cannot hold trim, so the car drifts off line.
  • β–ͺΒ Β Grinding on full lock. A failing servo whines and slips instead of turning the wheels.
  • β–ͺΒ Β Failures on wet runs. An unsealed housing lets dust and water in and shortens servo life.

What it does

Strong, sealed steering that holds its trim

This replacement servo drives the steering linkage with metal gears that resist stripping, a sealed housing that shrugs off water and mud, and a generous torque feel for heavy 1/8 scale chassis.

01
High torque

Strong turning effort suited to heavy 1/8 scale cars, buggies, and bashers.

02
Metal gears

Metal gear train resists stripping instead of wearing like plastic gears.

03
Waterproof housing

Sealed case handles wet grass, puddles, and muddy runs.

04
Horn included

Comes with a servo horn and mounting hardware for a direct fit.

Build & material

Metal gear train in a sealed aluminum case

The gear train is metal for wear resistance, the case is rigid aluminum, and output runs through a splined shaft with a sealed drive so grit stays out.

  • β–ͺΒ Β Metal gear train. Steel and metal teeth hold up to hard steering loads instead of chewing through.
  • β–ͺΒ Β Aluminum case. Rigid case stays square under torque and dissipates heat.
  • β–ͺΒ Β Sealed drive. Gaskets keep water and dust away from the gears and motor.
  • β–ͺΒ Β Splined output shaft. A standard spline mates to the included servo horn.
How to use

Remove, mount, link, and center

Swap the old servo in a few simple steps; center your radio trim before fitting the horn.

01
Center first

Set your transmitter steering trim to center before installing the horn.

02
Unbolt the old servo

Disconnect the lead, remove the mounting screws and horn, then lift it out.

03
Mount the new servo

Fit the horn, screw the servo down with the included hardware, and route the lead.

04
Link and test

Connect the steering rod, power on, and test left and right travel before driving.

Care & tips

Keep the linkage free and centered

A few habits keep the servo strong and responsive.

  • β–ͺΒ Β Center before fitting. Set trim to neutral before pressing the horn onto the spline.
  • β–ͺΒ Β Keep the rod free. Make sure the steering linkage does not bind at full lock.
  • β–ͺΒ Β Rinse mud off. Wash away dirt after muddy runs so the lead and case stay clean.
  • β–ͺΒ Β Check the spline. Tighten the horn screw and recheck it after the first few runs.

Will this fit my ARRMA 1/8 model?

It is a generic compatible servo; confirm voltage, spline count, and mounting spacing match your model before ordering rather than relying on brand fit alone.

Is the RC car included?

No. You receive one servo with horn and hardware; the car, receiver, and transmitter are sold separately.

What torque does it make?

Approximately 25kg/cm as a typical value; treat it as approximate and verify against your steering needs before buying.

Is it waterproof?

The sealed case is water resistant for wet runs and puddles, not submersible; avoid fully submerging the servo.

Do I need to center the horn?

Yes, set your transmitter steering trim to neutral before fitting the horn so left and right travel match.
