Will these panels affect jack point access on my frame?

No — these panels mount along the rocker line above the frame rail. Verify that your factory jack points remain clear before final installation. If you use aftermarket jack adapters, confirm fitment with your specific setup.

Do I need to paint these before or after installation?

Either sequence works. Many builders finish raw FRP panels off the truck for easier prep and paint coverage. If you install first, mask carefully around mounting zones to protect bare plastic during sanding and finishing.

How much ground clearance do these add or remove?

These are designed to follow the factory rocker contour with minimal extension, so they do not significantly alter your truck's overall ground clearance. Side clearance remains essentially stock — measure your specific setup before and after installation if you run tight setups or aftermarket suspension.
