Frequently Asked Questions

Are both sides included in the AC-SS15FDMU-AR kit?
Yes. The kit includes both the driver and passenger side skirts. The listed price covers the complete pair.

Does installation require drilling or cutting?
No. These skirts use existing OEM body clip locations and attachment points. No new holes are required, though a thin bead of body tape along the upper edge is commonly used to achieve a flush seal against the rocker panel.

How much ground clearance will I lose?
The AC-SS15FDMU-AR extends downward from the factory rocker panel position. The actual reduction in ground clearance depends on the vehicle’s ride height and suspension setup. Significantly lowered vehicles should verify curb and speed bump clearance during test-fit before driving aggressively.

Can these skirts be painted?
Yes. The gel coat surface accepts standard automotive paint. Lightly sand, prime with a flexible composite primer, then apply basecoat and 2K clear coat for a factory color match.

Installation Instructions

1. Lift and safely support the vehicle to access the underside of the rocker panel area
2. Remove the OEM side skirts by disengaging all push-pin clips and any mounting bolts
3. Clean the attachment surface to remove old adhesive and road debris
4. Test-fit both sides before applying any adhesive or final fasteners
5. Secure each skirt using OEM clips and apply body-side tape along the upper edge
6. Verify front-to-rear alignment and consistent gap on both sides
7. Reinstall any underbody splash shields or covers removed during disassembly
