RC crawler folks, listen up—this is a sweet upgrade part for your Traxxas TRX-4 Defender or TRX-6 G63. It's an aluminum servo horn (that's the arm connected to your steering servo) with a built-in spring designed for the locking differential function. Made from 6061-T6 aluminum, so it's lightweight but tough. The spring helps absorb shocks and impacts, which can save your servo from stripping or damage during rough trails. Fits part number 5669. Comes with all the hardware you need: a stainless steel screw, an aluminum collar, and a 3mm metal washer (use the washer to avoid gaps). Installation is pretty straightforward if you're familiar with RC maintenance. A nice, durable replacement or upgrade over stock plastic parts. If you're serious about your crawler's performance and durability, this is a solid pick.
