15T 7075 Alloy Adjustable Servo Horn - 1/5 Scale

This aftermarket 15T servo horn is precision machined from 7075-T6 aluminum for use on 1/5 scale ARRMA Kraton and Outcast 8S trucks. The straight arm includes an internal spring mechanism to absorb impacts and reduce shock transmitted to the servo. Three distinct mounting holes allow tie-rod length and steering throw adjustments so you can fine-tune response and end-point behavior. The part is indicated as a replacement for factory items ARA340165 and ARA320553 and cites compatibility with the original servo and GXservo options rated 70KG, X100KG, X120KG and X150KG in the source listing.

Designed for 15T spline servos in RC models, the horn is supplied with the necessary mounting hardware and bearing components to install as a like-for-like replacement when spline and mounting dimensions match the original. The adjustable holes provide flexibility to change mechanical advantage according to chassis layout and driver preference.

Offered as a CNC 7075 alloy direct replacement, this horn retains servo compatibility while providing adjustable linkage positions and improved impact damping for steering on 1/5 ARRMA trucks; follow the manufacturer's guidance for torque and fitment during installation.

Compare your servo's spline count (15T) and mounting footprint to the original horn. The supplier notes compatibility with the stock servo and GXservo models rated between 70KG and X150KG, but physical match is essential for correct fitment.
The source lists the horn as a replacement for factory part numbers ARA340165 and ARA320553; it is intended to substitute those items when dimensions align.
Yes. Moving the tie-rod to different holes alters leverage: inner holes reduce throw and increase precision, outer holes increase throw and speed of response. Make small adjustments and test to find the desired balance.
The package items listed by the source include the 15T horn, two servo saver axles, countersunk washer, two Grade 12.9 screws, a 3mm lock nut, a 6x12x5 bearing, and four stainless shims to assist fitting.
