This is a laser cut piece that fits the 99-13 trucks to easily mount the popular 40k trucool transmission cooler. It is 1/8″ thick aluminum and very sturdy. The top holes align with empty/existing holes in the front bracket of the vehicle, and slots allow you to slide the cooler around as needed. The bottom can be fastened to the existing crossmember piece easily (see pictures) with slight trimming.
No hardware is included, but 6mm or 1/4″ fasteners work well.
