But with multiple options available—from simple rocker panel extensions to full split-design side skirts—choosing the right solution can be confusing.
This comprehensive guide breaks down every option available for the Model Y Juniper, comparing designs, pricing, installation difficulty, and visual impact to help you make the perfect choice for your Tesla.
Quick Summary:
- Rocker Panel Extensions: $89.99 - Budget-friendly add-ons, subtle enhancement
- Split-Design Side Skirts: $219 - Best value, easier installation, professional look
- One-Piece Side Skirts: $299-399 - Seamless appearance, more challenging install
- Carbon Fiber Side Skirts: $599-799 - Premium materials, show car quality
Our Recommendation: Split-Design ABS Side Skirts ($219) offer the best balance of value, ease of installation, and visual impact for most Juniper owners.
Types of Side Skirts Explained
Understanding the Terminology
What Are Rocker Panels?
Rocker panels are the structural body panels that run along the bottom of your vehicle between the front and rear wheels, below the doors. On a stock Model Y Juniper, these are the painted body panels you see when looking at the car from the side.
What Are Side Skirts?
Side skirts are aftermarket components that attach to or cover the rocker panels to:
- Lower the visual appearance of the vehicle
- Create a more aggressive, sporty profile
- Improve aerodynamics by managing airflow along the sides
- Protect the rocker panels from road debris and damage
- Connect front lip and rear diffuser visually
The Three Main Types
Type 1: Rocker Panel Extensions (Add-Ons)
What They Are:
Small add-on pieces that attach to the bottom edge of your existing rocker panels, extending them downward by 1-2 inches.
Key Characteristics:
- Minimal coverage (bottom edge only)
- Subtle visual enhancement
- Easiest installation (30-45 minutes)
- Most affordable option
- Protects lower edge from chips
Best For:
- Budget-conscious buyers ($89.99)
- Those wanting subtle enhancement
- First-time modders
- Complementing other mods without dominating
Type 2: Split-Design Side Skirts (2-Piece per Side)
What They Are:
Full side skirts divided into two pieces per side (front section + rear section), designed specifically for easier installation and better fitment on the Model Y Juniper's unique body lines.
Key Characteristics:
- Full rocker panel coverage
- Two-piece design per side (4 pieces total)
- Easier alignment than one-piece
- Professional, seamless appearance
- Juniper-specific engineering
- Moderate installation difficulty
Best For:
- Most Juniper owners (best value)
- DIY installers (more forgiving)
- Those wanting complete transformation
- Balancing cost and impact
Type 3: One-Piece Side Skirts (Full Length)
What They Are:
Traditional full-length side skirts, one continuous piece per side covering the entire rocker panel from front wheel to rear wheel.
Key Characteristics:
- Full rocker panel coverage
- Single piece per side (2 pieces total)
- Seamless appearance (no split line)
- More challenging installation
- Requires helper for alignment
- Premium appearance
Best For:
- Show car builds
- Those prioritizing seamless look

Split-Design Side Skirts: The Smart Choice
The split-design side skirts represent the sweet spot for most Model Y Juniper owners. Here's why they've become the most popular choice:
Why Split-Design Works Better for Juniper
Juniper-Specific Engineering
The Model Y Juniper's body lines are different from the classic Model Y, with unique contours and mounting points. Split-design side skirts are engineered specifically for these changes:
- Front Section: Designed to align with Juniper's front wheel arch and door contours
- Rear Section: Engineered to match Juniper's rear wheel arch and quarter panel lines
- Split Point: Strategically placed to hide the seam and allow independent adjustment
Installation Advantages
| Installation Aspect | Split-Design | One-Piece |
|---|---|---|
| Alignment Difficulty | Easier (align each section independently) | Harder (must align entire length at once) |
| Handling | Easier (smaller, lighter pieces) | Awkward (long, unwieldy piece) |
| Adjustment | Can adjust front/rear independently | Must get entire piece perfect |
| Helper Required | Recommended but not essential | Highly recommended |
| Error Forgiveness | High (can reposition sections) | Low (one chance to get it right) |
Split-Design Features
Design Features:
- ✅ Hidden Seam Design: Split point located where body lines naturally create shadow, making seam virtually invisible
- ✅ Precision Fitment: Each section engineered for specific body contours
- ✅ Overlap Design: Sections overlap slightly for seamless appearance
- ✅ Independent Adjustment: Fine-tune front and rear sections separately
- ✅ Wheel Arch Integration: Perfectly follows Juniper's wheel arch lines
Material & Finish Options:
- ABS Plastic: $219 (4 finish options)
- Carbon Fiber: $599-699 (glossy or matte)

Frequently Asked Questions
Q1: What's the difference between rocker panels and side skirts?
A: Rocker panels are the factory body panels between your wheels below the doors. Side skirts are aftermarket components that attach to or cover these panels to lower the visual appearance and improve aerodynamics. Rocker panel extensions are small add-ons to the bottom edge, while full side skirts cover the entire rocker panel area.
Q2: Why choose split-design over one-piece side skirts?
A: Split-design side skirts offer several advantages:
- Easier installation (align each section independently)
- More forgiving for DIY installers
- Better fitment on Juniper's unique body lines
- Easier to handle (smaller, lighter pieces)
- Lower cost ($219 vs $299-399 for ABS)
- Virtually invisible seam when properly installed
One-piece skirts offer a seamless look but are more challenging to install and more expensive.
Q3: Will side skirts reduce my ground clearance?
A: Yes, but minimally:
- Rocker Panel Extensions: 0.5-1 inch reduction
- Full Side Skirts: 1-1.5 inch reduction
This is generally not an issue for normal driving. The Model Y Juniper has sufficient ground clearance (6.6 inches stock) that a 1-1.5 inch reduction still leaves 5.1-6.1 inches, which is adequate for most situations. Avoid steep driveways and speed bumps at sharp angles.
Q4: Can I install side skirts myself?
A: Yes! Side skirt installation is DIY-friendly:
- Rocker Panel Extensions: Very easy, 30-45 minutes, no helper needed
- Split-Design Side Skirts: Moderate difficulty, 45-60 minutes, helper recommended
- One-Piece Side Skirts: More challenging, 60-90 minutes, helper highly recommended
All use 3M VHB adhesive tape (no drilling required). We provide detailed installation guides and video tutorials.
Q5: Will the split seam be visible on split-design side skirts?
A: When properly installed, the seam is virtually invisible. The split point is strategically placed where the Juniper's body lines create natural shadows. The sections also overlap slightly, and the seam aligns with existing body contours. From 3+ feet away, most people cannot detect the split.
Q6: Are rocker panel extensions worth it?
A: It depends on your goals:
- Worth it if: You want subtle enhancement, have a tight budget ($89.99), or are complementing other mods
- Not worth it if: You want dramatic transformation (full side skirts offer much more impact for $129 more)
For most buyers, spending the extra $129 for split-design side skirts provides significantly more visual impact and better value.
Q7: Which finish should I choose for ABS side skirts?
A: Finish recommendations by vehicle color:
- White, Red, Blue (bright colors): Glossy Black or Glossy Carbon Pattern
- Black, Midnight Silver (dark colors): Matte Black or Matte Carbon Pattern
- Gray, Silver: Any finish works well
- Want carbon look without cost: Glossy or Matte Carbon Pattern
Q8: Do side skirts improve aerodynamics?
A: Yes, side skirts improve aerodynamics by:
- Managing airflow along the vehicle sides
- Reducing turbulence under the vehicle
- Working with front lip and rear diffuser for complete aero package
- Potential 0.5-1% range improvement at highway speeds
However, the primary benefit is aesthetic. Don't buy side skirts solely for aerodynamic improvement.
Q9: Will side skirts fit classic Model Y (2020-2024)?
A: No. The 2025 Model Y Juniper has different body lines, door contours, and wheel arch shapes compared to the classic Model Y. Side skirts are NOT compatible between generations. Always verify you're purchasing Juniper-specific side skirts.
Q10: Can I paint ABS side skirts to match my car color?
A: Yes! ABS side skirts can be professionally painted to match your vehicle's exact color. This is actually an advantage over carbon fiber, which is typically only available with clear coat over the carbon weave. Painting costs $200-400 professionally depending on your location.
