INJORA CNC Aluminum Bumper Mount for TRX4M Defender & Bronco 1/18 RC Crawler Upgrade
INJORA CNC Aluminum Bumper Mount for TRX4M Defender & Bronco 1/18 RC Crawler Upgrade
The INJORA CNC aluminum front and rear bumper mount is a precision-machined upgrade for 1/18 scale TRX4M RC crawlers, designed to replace the stock plastic part. Made from black anodized aluminum, it weighs only 2 grams and offers improved durability and corrosion resistance compared to the original. This mount is compatible with the TRX4M Defender and Bronco models.
Why Replace the Stock Plastic Bumper Mount?
Stock plastic bumper mounts on RC crawlers can flex or crack under stress, especially during rough trail runs or heavy impacts. The INJORA CNC aluminum version eliminates those weak points. Machined from solid aluminum, it provides a rigid mounting point that helps keep your bumper securely in place. The black anodized finish not only looks great but also resists scratches and corrosion, so it holds up well in muddy or wet conditions.
What to Check Before Buying
This bumper mount is specifically designed for the Traxxas TRX4M chassis in 1/18 scale, including the Defender and Bronco body styles. Before purchase, confirm that your RC car model matches these specifications. The mount replaces the factory plastic piece directly, but installation is straightforward for hobbyists with basic tools.
Lightweight Design and Weight Impact
Weighing just 2 grams (0.07 ounces), this aluminum mount adds negligible weight to your rig. That’s important because extra weight on the front or rear can affect crawling performance, especially on steep inclines. By keeping the weight low, the mount helps maintain the truck’s balance and agility. Despite being light, the CNC aluminum construction is strong enough for serious off-road use.
