Ready to upgrade your TRX-4M Bronco or Defender? This 4-piece set of aluminum shock absorbers is a popular and straightforward mod. Made from lightweight but durable aluminum alloy, they replace the stock plastic shocks, potentially improving your crawler's suspension performance and giving it a much cooler, more custom look – especially in this bright red finish. The set includes 4 shocks and 8 mounting screws. The dimensions are: total length about 59mm (2.33 inches), hole-to-hole length (the eye-to-eye measurement for mounting) is 52mm (2.05 inches), and the diameter is 10mm (0.39 inches). They compress down to about 39mm. Installation is usually pretty simple with basic RC tools, and they're a direct fit for the 1/18 scale TRX-4M models. They can help with articulation and handling on rough terrain. A fun, affordable way to personalize and potentially improve your tiny truck!
