These are simple parts but having them pre-made saves a lot of time when your sprint gets run over and that top wing is torn up. Ron at Rocket Products researched and tested several materials to find the best combination of strength and flexibility and is now releasing them for your Sprint Car! Available in a variety of colors, (including 'Bob Light' orange!). The 'New Wing Kit' is the choice when you have built a new wing; it includes two long struts (wing top) and one short strut (under wing). The 'Extra Strut Kit' are spare parts to make easy repairs if the wing is damaged. Includes four long struts and two short struts. Also shown is a handy tool (may be in any color, no choice) to drill the holes for the struts to assure your side plate is 90 degrees to the wing top. This tool is NOT INCLUDED but available for purchase by clicking this LINK.
