Will these affect jack point access on the rocker line?

These skirts mount to the factory rocker area. Before installation, verify your jack point locations on the vehicle's pinch weld — you may need to use a low-profile jack or offset placement under the factory frame rail to avoid contact. Plan your lifting strategy ahead of time to avoid panel damage during service.

Do I need to paint these before installation, or can I bolt them on raw?

These ship in raw FRP condition. You can apply your chosen paint or powder coat before bolting on, or install them unpainted and finish them later. Prep the surface with light sanding before paint application for best adhesion. Installation can happen at either stage — timing is your preference.

Will a lowered suspension cause ground clearance issues with the wide body design?

The Blaze profile extends outward more than upward, so suspension drop alone shouldn't scrape the panels. However, aggressive lowering combined with rough road surfaces may risk contact. Check fitment once installed and verify clearance at your typical driving spots, especially over speed bumps and driveway approaches.
