Installing roof rails on your Jeep Grand Cherokee can open up a world of possibilities for carrying gear and outdoor equipment. Whether you need extra space for bikes, luggage, or kayaks, roof rails are a smart upgrade. Many Grand Cherokee owners think this process is complex, but with the right approach, you can handle it yourself in a few hours.
Here’s a straightforward guide to help you install roof rails safely and efficiently.
Why Install Roof Rails On Your Jeep Grand Cherokee?
Adding roof rails boosts your Jeep’s practicality. You gain more storage options for trips, and your car’s resale value can improve. Roof rails also make it easier to attach crossbars, cargo boxes, or racks for sports equipment.
Many factory models come without rails, especially base trims. If you plan on using your SUV for travel or adventure, installing roof rails is a cost-effective way to make your vehicle more versatile.
What You’ll Need
Before starting, gather these tools and materials:
- Jeep Grand Cherokee roof rail kit (OEM or aftermarket)
- Torx bit set (often T25 or T30)
- Socket wrench
- Plastic trim removal tool
- Measuring tape
- Masking tape
- Thread locker (optional, for extra security)
- Step ladder
- Microfiber cloth
Buying an OEM kit ensures a perfect fit, but quality aftermarket rails can also work if you check compatibility. Avoid using random rails not made for your Jeep—they may not mount securely.
Comparing Roof Rail Types
Choosing the right roof rails is important. Here’s a quick comparison to help you decide:
| Type | Material | Weight Capacity | Typical Price |
|---|---|---|---|
| OEM | Aluminum/Steel | 150-165 lbs | $250-$400 |
| Aftermarket | Aluminum/Plastic | 120-165 lbs | $120-$300 |
OEM rails tend to be more durable and fit better, while aftermarket options can save money but may require more adjustments.
Step-by-step Installation Guide
Follow these steps for a successful roof rail installation:
1. Prepare Your Work Area
Park your Jeep on a flat surface and ensure the roof is clean. Use a microfiber cloth to remove dust and debris, which helps prevent scratches.
2. Remove Roof Trim
Most Grand Cherokees have a plastic or rubber strip where the rails will go. Use a plastic trim removal tool to gently lift this strip. Work slowly to avoid breaking clips. Some models may have screws under the trim—remove these with a Torx bit.
3. Position The Roof Rails
Lay the rails on the roof to check alignment. Use a measuring tape to ensure both sides are even. Place masking tape on the roof near mounting points to avoid scratches during adjustments.
4. Attach Mounting Brackets
Each rail has brackets that line up with factory holes in the roof. Align these brackets carefully. Secure them with bolts from your kit, tightening by hand first.
5. Secure Rails
Use your socket wrench and Torx bit to fully tighten each bolt. For extra safety, you can apply a drop of thread locker to each bolt before tightening. Avoid over-tightening, as this can strip threads.
6. Reinstall Or Adjust Trim
If your kit allows, trim the original roof strip to fit around the new rails. Some kits include new covers. Snap these back into place for a clean finish.
7. Double-check Everything
Give each rail a firm shake to ensure it’s solid. Check for gaps or loose bolts. If you plan to add crossbars or cargo boxes, install them now and test for fit.
Common Mistakes To Avoid
Many beginners make simple errors that can cause frustration or damage.
- Skipping alignment: Not measuring both sides leads to crooked rails.
- Over-tightening bolts: This can strip threads or crack plastic parts.
- Using the wrong kit: Some rails look universal but don’t match the Jeep’s mounting points.
- Forgetting weatherproofing: If your roof has exposed holes, use sealant to prevent leaks.
Cost, Time, And Difficulty
Here’s a quick overview to help you plan:
| Factor | Details |
|---|---|
| Cost | $150–$400 (parts only) |
| Time | 1–2 hours |
| Difficulty | Easy to moderate |
Most owners find this a reasonable weekend project. If you have basic tools and patience, you’ll save on labor costs.
Real-world Tips
- Test-fit everything before final tightening. This prevents mistakes that require removing and reinstalling parts.
- Check your owner’s manual for any specific torque settings.
- Some aftermarket rails need minor modification—read reviews and instructions before buying.
- After installation, recheck the bolts after a week of driving. Vibration can loosen new hardware.
Safety And Legal Considerations
Roof rails add height and weight to your vehicle. Be aware of:
- Garage clearance: Measure your new total height before entering parking structures.
- Weight limits: Never exceed the recommended load. Doing so can damage your roof and affect driving safety.
- Insurance: Some policies require you to list modifications. Double-check with your provider.
