Tailgate side braces.
We have reproduced what Jeep FINALLY corrected in 1971, a set of braces for the sides of the tailgate to eliminate the flex, cracking and disforming of the tailgate.
These weld in the side braces stiffen the tailgate to eliminate cracks and make the tailgate seal better to the body.
Another made in USA Partsdude4x4 exclusive!!
