ECB 3D Printing has made a custom web headache rack for the RC4WD K10 and Blazer. These come with two length legs so you can install with or without our bed toolbox. These are sculpted to follow the roof line of the truck nicely and give that custom look that covers up the sharp right angled roof line that was designed by RC4WD.
 
Included is one custom web headache rack and 4 legs (2 left and 2 rights) in black.
