Sprint Car 16" Aero Top Wing Tree

16" Top wing tree. Aero. Plated 4130. Aluminum adjusters. Designed for Wedge style chassis to keep the wing at an optimal adjustment angle. 3/4" adjustment holes, with a total of 3" of adjustment. "X" design for lateral and horizontal strength. The squished tube aero tree is designed to give you the least amount of drag possible from your aero package. The sleek, narrow design keeps the smallest possible aero profile, allowing the air to flow around the upright rather than hitting a wider surface and slowing your car down by increasing drag. Comes with internal sliders. Adjuster pins not included.
