This bumper mount is great for bodies that line up with the stock frame rails vertically and horizontally.
This will move your front bumper mounting holes so that they are right up against the end of the frame rails and centered with them.
We now label our bumper mounts based off of the frame rails because it is easier for you to do the math this way.
For instance:
We would call a stock TRX4 Land Rover front bumper mount an "11.5H 5.0V" because the bumper mount surface extends 11.5mm from the end of the frame rails and sits up/down 5.0mm from the center of the frame rails.
Example images:
11.5mm Horizontal offset
7mm Vertical offset
This mount is a ZeroH ZeroV.
That means the bumper mount face would be even with the end of the chassis and Zero offset vertically.
