This 23T aluminium servo horn fits TRX4 steering assemblies and is identified by model TRX4023TA/3H. It upgrades the stock horn to deliver a more positive link to the servo while an internal spring absorbs shocks that could damage servo gears.
Machined from 6061 T6 aluminium with a straight-arm layout, the horn balances light weight with improved stiffness at the output. The integrated spring reduces impact force to the servo, and several hole positions allow fine tuning of tie rod angle and steering throw.
Fitment tip: the spring mechanism makes the horn thicker than thin alloy arms. When installed in the original TRX-4 servo spot, flip the support tie rod angle to gain clearance; this does not alter the front reverse steering gear location.
