Install Frame Rail Reinforcements
We will be installing reinforcement plates onto the frame rails. This will require drilling
two ¾” holes for each rail.
Start on the passenger side frame rail. The hole that was used to hole the line tab is in
the same position as one of your holes. (see picture) Use one of the reinforcement
plates as a template to mark out the other hole.
Drill out the ¾” hole only on the inner side of the frame rail. Do not drill through both
walls of the frame rail. We found that a unibit works best.
