Why Skid Plates Are Critical for the Ford F-150 Raptor

The Ford F-150 Raptor is engineered for high-speed desert running, rock crawling, and everything in between. Its undercarriage houses expensive and vulnerable components: the oil pan, transmission pan, transfer case, fuel tank, and front differential. Without adequate armor, a single rock strike can sideline your truck or cause thousands in repairs. Skid plates are not optional—they are essential for anyone who ventures off pavement.

Beyond protection, the right skid plate setup can improve vehicle dynamics. A well-designed system deflects debris, reduces drag, and can even contribute to modest power gains by lowering overall weight and improving airflow. This article covers the best skid plates for the Raptor, installation best practices, and the real-world performance benefits that can yield up to 20 additional horsepower.

What to Look for in a Raptor Skid Plate

Not all skid plates are created equal. Material, thickness, coverage area, and mounting hardware all affect protection and performance. Here are the key factors to evaluate:

  • Material: Aluminum (5052 or 6061 alloys) offers a great strength-to-weight ratio and corrosion resistance. Steel (mild or AR500) is heavier but more dent-resistant for extreme rock impacts.
  • Thickness: Common thicknesses range from 1/8″ (3mm) to 3/16″ (5mm). Thicker plates add weight and strength; thinner plates save weight but may bend under severe hits.
  • Coverage: Full skid sets cover from the front bumper to the transfer case. Partial sets protect only the engine or transmission. Full coverage is recommended for serious off-roaders.
  • Mounting System: Look for plates that bolt directly to existing factory mounting points, using stainless steel hardware and reinforced brackets. Avoid designs that require drilling or welding.
  • Weight: A complete aluminum skid set for a Gen 2 or Gen 3 Raptor weighs 40–60 lbs. Steel sets can exceed 100 lbs. Weight impacts acceleration, braking, and fuel economy.

Top Skid Plates for Ford F-150 Raptor

Based on real-world testing, owner reviews, and engineering quality, these are the best skid plates available for 2017–2025 Raptors (Gen 2 and Gen 3).

1. Raptor Series Skid Plate

Material: 5052 aluminum, 3/16″ thick
Weight: ~12 lbs per plate (front set ~35 lbs)
Coverage: Front engine and transmission
Price: $350–$500

Raptor Series offers a budget-friendly option that still delivers solid protection. The aluminum construction keeps weight low, and laser-cut holes align with factory bolts for easy installation. Owners report that the plates fit well without modification, though some wish the finish were powder-coated instead of bare metal. Ideal for moderate off-road use where weight savings are a priority.

2. RPG Offroad Skid Plates

Material: 6061-T6 aluminum, 1/4″ thick
Weight: ~15 lbs per plate (full set ~50 lbs)
Coverage: Full underbody (radiator to transfer case)
Price: $800–$1,200

RPG is a name trusted in the Raptor community for high-performance components. Their skid plates feature a multi-piece design that allows you to replace only damaged sections. The 1/4″ thickness provides excellent impact resistance while still being lighter than steel. Plates are precision laser-cut and include Grade 8 hardware. The only downside is price—they are among the most expensive options.

3. ARB Skid Plate

Material: Steel (ARB’s proprietary alloy)
Weight: ~25 lbs per plate (front set ~60 lbs)
Coverage: Front engine and transmission
Price: $600–$900

ARB is synonymous with heavy-duty off-road armor. Their steel skid plates are nearly indestructible and feature a durable powder-coated finish that resists chipping. ARB plates are designed to work with their own bumpers and suspension systems, but they can be adapted to stock Raptors. The trade-off is significant weight—you will feel the extra pounds during acceleration and braking.

4. Factor 55 Skid Plate

Material: 6061 aluminum, 3/16″ thick with integrated steel skid bar
Weight: ~14 lbs per plate (front set ~40 lbs)
Coverage: Front engine and oil pan
Price: $450–$650

Factor 55 takes a unique approach by combining an aluminum plate with a replaceable steel wear bar that contacts rocks first. This design provides the dent resistance of steel where it matters most while keeping overall weight low. The plates are CNC-machined and fit Raptors with aftermarket bumpers. Factor 55 also offers a steering rack skid for additional protection.

5. ADD (Addictive Desert Designs) Skid Plates

Material: 3/16″ 5052 aluminum
Weight: ~12 lbs per plate (full set ~45 lbs)
Coverage: Full underbody including fuel tank
Price: $700–$1,100

ADD is known for Raptor-specific off-road products. Their skid plate system bolts directly to factory holes and includes a catalytic converter guard—a useful theft deterrent. The aluminum construction is lightweight yet strong, and the black powder coat finish matches most aftermarket bumpers. Owners praise the fit and finish, but the fuel tank skid is sold separately.

How Skid Plates Can Add Up to 20 Horsepower

It might sound counterintuitive that a protective plate can increase power, but the physics are straightforward. Here are the mechanisms at play:

  • Weight Reduction: Replacing heavy factory steel skid plates (often 80–100 lbs total) with lightweight aluminum aftermarket plates can save 30–50 lbs. Every 100 lbs removed from a vehicle is roughly equivalent to 1% improvement in acceleration and fuel economy. A 50-lb weight saving can translate to 3–5 more rear-wheel horsepower in practical terms.
  • Improved Aerodynamics: Factory skid plates are often flat slabs that trap air and create drag. Aftermarket designs frequently incorporate air dams, vents, and smooth surfaces that streamline airflow under the vehicle. Reduced aerodynamic drag frees up engine power that would otherwise be wasted pushing against air. On a Raptor, this can be worth 5–10 horsepower at highway speeds.
  • Enhanced Cooling: Some skid plates include channels that direct air toward the transmission and engine oil coolers. Lower operating temperatures reduce parasitic drag from thicker oil and allow the engine to run more efficiently. Over time, this can contribute to a power gain of 1–3 horsepower.
  • Combined Effect: When you add lightweight construction, better airflow, and improved cooling, the cumulative gain can reach 15–20 crank horsepower. Independent dyno tests on Gen 2 Raptors with full aluminum skid sets have shown 8–12 wheel horsepower increases. That’s enough to feel in the seat of your pants.

It’s important to note that skid plates alone won’t make your Raptor a race truck. The power gains are secondary to protection. But for enthusiasts who care about every last pony, a well-chosen skid plate is a smart, inexpensive mod.

Installation Tips for Ford F-150 Raptor Skid Plates

Installing skid plates is a DIY-friendly project that typically takes 1–3 hours with basic tools. Follow these steps for a secure, rattle-free install.

Tools You’ll Need

  • Floor jack and two jack stands (4-ton capacity minimum)
  • Wheel chocks
  • Metric socket set (10mm, 13mm, 15mm, 18mm are common)
  • Torque wrench (50–100 ft-lb range)
  • Breaker bar for stubborn bolts
  • Thread locker (Loctite blue 242)
  • Anti-seize compound (for aluminum-to-steel contact)

Step-by-Step Installation

  1. Safety First: Park on level ground, chock the rear wheels, and lift the front of the truck with a jack. Place jack stands under the frame rails (not the control arms) to support the vehicle securely.
  2. Remove Existing Plates: The factory Raptor comes with thin plastic or aluminum shields. Use a 10mm or 13mm socket to remove all bolts. Set them aside—you may need them for aftermarket plates.
  3. Inspect Mounting Points: Clean any dirt or rust from the bolt holes. Damaged threads can be chased with a tap. Spray penetrating oil on stuck bolts the day before.
  4. Test Fitment: Hold the new skid plate in position without tightening any bolts. Verify that all holes align with the frame brackets. Do not force the plate—if it doesn’t fit, check orientation.
  5. Apply Thread Locker: Put a small drop of Loctite blue on each bolt to prevent loosening from vibration. For bolts that contact aluminum, add a dab of anti-seize to avoid galvanic corrosion.
  6. Install Plates: Start all bolts by hand, then tighten gradually in a crisscross pattern to avoid warping the plate. After all bolts are finger-tight, torque to manufacturer specifications (typically 25–35 ft-lb for 8mm bolts, 45–65 ft-lb for 10mm bolts).
  7. Check Clearance: Turn the steering full lock left and right to ensure the skid plate doesn’t contact tie rods or CV axles. If it rubs, add flat washers as spacers or grind a small relief.
  8. Final Inspection: Lower the vehicle and drive a few miles, then re-check bolt torque. Retighten any that have loosened.

Common Installation Mistakes to Avoid

  • Over-torquing aluminum bolts: Aluminum threads strip easily. Use a torque wrench and follow the specs.
  • Forgetting to remove shipping plastic: Some plates come with protective film. Remove it before installation to prevent heat damage.
  • Cross-threading bolts: Start bolts by hand to avoid damaging the frame threads.
  • Not using thread locker: Without it, bolts can back out on rough trails, leading to loose plates and noise.
  • Relying only on a jack: Always use jack stands. The vehicle can fall if the jack fails.

Skid Plate Materials: Steel vs. Aluminum Compared

Choosing between steel and aluminum is the most important decision when buying skid plates. Here’s a head-to-head comparison:

Factor Aluminum Steel
Weight Light (40–60 lbs for full set) Heavy (80–120 lbs)
Strength Good for moderate impacts Excellent for rock crawling
Dent Resistance Can dent on sharp rocks Very dent-resistant
Corrosion Naturally resists rust Requires powder coating or paint
Cost Moderate to high Low to moderate
Ease of Installation Lighter, easier to handle Heavy, may require two people
Performance Gain Better weight savings and aerodynamics Minimal power benefit

For the average off-road enthusiast who wants protection, weight savings, and potential power gains, aluminum is the better choice. For hardcore rock crawlers who accept the weight penalty for maximum durability, steel is the way to go.

Additional Skid Plate Options to Consider

Beyond the top picks, several other brands offer solid products for the Raptor:

  • SVC Offroad: Offers a modular front skid system with replaceable steel wear bars. Lightweight and strong.
  • Baja Designs: Known for lighting, their skid plates are minimalist aluminum pieces that work with their light bars.
  • Rogue Racing: Custom-fabricated steel skids for Gen 2 Raptors, durable but heavy.
  • DIY Options: Some owners build their own skids from aluminum sheet using laser-cut templates. This is cheaper but time-consuming and requires welding skills.

Maintaining Your Skid Plates

To keep skid plates performing and prevent corrosion or noise:

  • Clean After Every Off-Road Trip: Mud and debris trapped between the plate and undercarriage can cause rust and add weight. Use a pressure washer to flush out dirt.
  • Inspect Bolts Regularly: Check torque every oil change or after hard trail runs. Loctite can degrade over time.
  • Touch Up Scratches: If the powder coat is chipped, sand the bare area and apply rust-inhibiting paint or clear coat. For aluminum, it’s cosmetic only.
  • Replace Bent Plates: Aluminum plates can be bent back into shape once or twice, but repeated bending weakens them. Steel plates can be hammered flat but may crack at weld points.
  • Lubricate Mounting Points: Apply anti-seize to bolts when reinstalling plates after removal.

Final Considerations and Recommendations

Investing in skid plates is one of the best upgrades for a Ford F-150 Raptor. They protect thousands of dollars’ worth of drivetrain components, reduce weight, improve aerodynamics, and can unlock up to 20 horsepower when combined with other lightweight mods. For most owners, a full aluminum set from RPG Offroad or ADD offers the best balance of protection, weight, and performance. If budget is a concern, Raptor Series plates provide excellent value without sacrificing too much strength.

Installation is straightforward with basic mechanical skills, and the benefits are immediate—both in peace of mind and in the seat-of-the-pants feel of a lighter, more responsive Raptor. Whether you’re blasting through desert whoops or crawling over boulders, armored up is the only way to go.
