Rocket Chassis black aluminum spoiler kit. This kit uses a short 8" break away panel to minimize downforce loss in the event of losing the breakaway portion of the spoiler. Kit includes everything needed to mount spoiler onto your chassis. Includes hinges, spoiler sides / supports, break away and spoiler blade. This kit is 8" tall, but allows you to take a 2" portion of the spoiler off to make it a 6" spoiler. Works with both XR1 and XR2 Rocket late models.
