Want to make your 1/28 scale RC car tougher and more precise? This metal upgrade kit is packed with high-quality aluminum alloy parts to replace the stock plastic ones on your WLtoys model (fits K969, K979, K989, K999, P929, P939 and similar). You get a full set: front and rear suspension brackets, upper and lower swing arms, steering cups, CVD drive shafts, and all the necessary screws and gaskets. These parts are lightweight but super durable, adding strength and rigidity without weighing your car down. That means better handling, less flex in the chassis, and more reliable performance when you're bashing around. The servo guards (steering cups) specifically protect your steering servo saver during impacts. Installation is straightforward if you're comfortable with basic RC maintenance. It's a great way to improve your car's durability and give it a more premium, custom look. Perfect for hobbyists who want to take their mini RC to the next level!
