Powmok AMK TRX4 Aluminum Servo Mount - 7075 Alloy, 13g, On-Axle 4-Link Upgrade for 1/10 RC Crawler (Black)
Powmok AMK TRX4 Aluminum Servo Mount - 7075 Alloy, 13g, On-Axle 4-Link Upgrade for 1/10 RC Crawler (Black)
For 1/10 scale RC crawlers like the Traxxas TRX4, this servo mount from Powmok (AMK series) converts the stock Panhard steering setup to a bridge axle servo with a 4-link suspension design. Machined from 7075 aluminum alloy via CNC, it weighs just 13 grams (0.46 oz) and installs without replacing the steering rod. Rated 4.8 out of 5 stars from 23 customer reviews, it's a popular choice for TRX4 owners looking to improve steering response and suspension articulation.
Why Switch to a 4-Link Suspension with On-Axle Servo?
Moving the servo to the axle and adopting a 4-link setup changes how your TRX4 handles. The bridge axle servo eliminates the need for a Panhard bar, reducing binding and allowing the axle to articulate more freely. This mount is designed for non-destructive installation — you keep the original steering rod. It's a direct-fit upgrade for 1/10 TRX4 chassis.
