Tools & Materials Needed

Body kit panels (front bumper, rear bumper, side skirts)
Drill with assorted bits (1/2″ recommended)
Screwdriver set, trim removal tools
Measuring tape, painter’s tape, marker
Automotive-grade screws, bolts, and fasteners
Safety gloves, goggles, and dust mask
Sandpaper (220–400 grit for fiberglass edges)
Automotive adhesive (optional for reinforcement)

Step 1: Preparation & Safety

Work Environment:
- Park your vehicle on a flat, well-lit surface. Use jack stands if working underneath.
- Clean the installation area to avoid dust interference.
Dry-Fit Testing:
- Hold each body kit panel against the vehicle to identify alignment issues or gaps.
- For fiberglass kits, sand rough edges gently to ensure smooth contact points.
Documentation:
- Take photos of the original bumper’s mounting points and hardware for reference.

Step 2: Front Bumper Installation

Remove the Stock Bumper:
- Unscrew bolts from the wheel wells, grille, and undercarriage.
- Detach any sensors, fog lights, or wiring harnesses carefully.
Mark Drill Points:
- Align the new bumper with the vehicle’s frame.
- Use painter’s tape to mark hole locations from the original bumper onto the new panel.
Drilling & Mounting:
- Drill pilot holes slowly to avoid cracking fiberglass. Use a 1/2″ bit for factory-sized holes.
- Secure the bumper using OEM screws and brackets. Reattach sensors/lights if applicable.
- Double-check alignment before tightening bolts fully.

Step 3: Rear Bumper Installation

Repeat the front bumper process:
1. Remove the stock bumper and transfer mounting points.
2. Drill carefully, especially near exhaust or rear sensors.
3. Secure with OEM hardware and test fitment.

Step 4: Side Skirt Installation

Dry-Fit & Adjust:
- Hold the side skirt against the vehicle’s rocker panel. Check for gaps or warping.
- If the skirt buckles, consult a professional for adjustments (common with low-quality kits).
Secure with Screws:
- With an assistant’s help, align the skirt flush with the body.
- Drill starter holes into the fender wells and door sills.
- Attach screws discreetly (hidden when doors are closed).
Reinforcement (Optional):
- Apply automotive adhesive along contact points for added stability.

Post-Installation Checklist

Test Fitment:
- Ensure all panels align evenly with 1–2mm gaps between parts.
- Check for rattling or loose screws after a short test drive.
Paint & Finish:
- If unpainted, sand panels smoothly and apply primer/paint matched to your vehicle.
Maintenance Tips:
- Avoid high-pressure car washes for 48 hours to let adhesives cure.
- Inspect fasteners monthly for tightness.

Troubleshooting Common Issues

Gaps or Misalignment:
- Low-quality kits often require professional modification. Seek a body shop for fiberglass reshaping.
Cracked Fiberglass:
- Repair with fiberglass resin and sand smooth before painting.
Loose Panels:
- Reinforce with additional screws or automotive-grade adhesive.

Why Quality Matters

Investing in OEM or reputable aftermarket kits ensures precise fitment. Cheap replicas may save money upfront but often lead to costly adjustments. Always verify reviews and return policies before purchasing.
