Will this lip reduce my ground clearance?

Ground clearance change depends on the GMX profile depth and your vehicle's current ride height. Measure the lowest point of your factory bumper, then compare against the lip extension before installation to confirm clearance for your driveway and typical driving routes.

Can I flex this without permanent cracking?

FRP has inherent flex and resists stress cracking better than rigid materials, making it ideal for dynamic driving. Avoid repeated hard impacts or high-force flexing — the material is designed to absorb minor road contact, not to be bent intentionally.

What prep work does the surface need?

Sand and prep the surface with your preferred grit before applying your chosen primer and topcoat.
