Upgrade your HPI BLITZ truck with this White Composite Main Chassis from the high performance BLITZ ESE truck. This replaces the stock black nylon chassis with a stiffer composite main chassis that quickens the overall response of the truck. Not only does the white chassis material enhance the performance and style of the truck, it lets you know at a glance which part is the high response performance part. It’s precision made to exact HPI factory specifications for a perfect bolt-on fit.
