Mini-Z 4x4 owners, this belt crawler unit is about to completely transform your RC experience! This conversion kit lets you turn your Mini-Z into a proper off-road crawler that can handle pretty much any surface - dirt, gravel, grass, you name it. The catappi design gives your RC that rugged, aggressive look while actually improving off-road performance. It comes as an assembly kit, so you get to put it together yourself (which is half the fun of RC hobbies!). Just a heads up - this is just the crawler unit itself, so you'll need your Mini-Z 4x4 chassis, plus batteries and all the usual RC essentials. Once installed, you'll be amazed at how much more capable your Mini-Z becomes off-road. The belt system provides smooth, controlled crawling action that's perfect for technical terrain. Whether you're building a trail truck, rock crawler, or just want more versatility from your Mini-Z, this conversion opens up a whole new world of driving possibilities. The quality is exactly what you'd expect from Kyosho - precise fit, durable materials, and performance that matches the looks. If you're ready to take your Mini-Z beyond smooth surfaces and into the great outdoors, this crawler kit is exactly what you need!
