The ARIES Aluminum Skid Plate is a popular aftermarket upgrade for truck and SUV owners who want to protect their vehicle's undercarriage without adding unnecessary weight. Priced at $250, this skid plate promises enhanced durability for off-road and rough-terrain driving. But does it really improve power? In this comprehensive guide, we’ll walk you through everything you need to know: the installation process, the material benefits, real-world performance gains, and whether this $250 investment is worth it. We’ll also answer common questions and provide expert tips to get the most out of your ARIES skid plate.

Why Choose an Aluminum Skid Plate Over Steel?

When it comes to underbody protection, you have two primary material choices: steel and aluminum. The ARIES Aluminum Skid Plate is a standout for several reasons:

  • Weight savings: Aluminum is roughly one-third the weight of steel, which means less unsprung mass and better fuel economy. A typical ARIES aluminum skid plate weighs around 15–20 pounds, compared to 40–50 pounds for a comparable steel plate.
  • Corrosion resistance: Aluminum naturally forms a protective oxide layer, making it ideal for wet, salty, or muddy environments. Steel skid plates often require painting or powder coating to prevent rust.
  • Ease of installation: Because aluminum is lighter, you can install the skid plate by yourself without needing a helper or heavy-duty jack. The provided hardware is usually corrosion-resistant as well.
  • Strength-to-weight ratio: Modern aluminum alloys (such as 6061-T6) offer high tensile strength, capable of absorbing impacts from rocks and debris without cracking or bending permanently.

However, steel does have an edge in extreme rock-crawling scenarios due to its ability to withstand sharp impacts without puncturing. For most overlanding or daily driving with occasional off-road use, aluminum is the better balance.

Installation Process: Step-by-Step Guide

Installing the ARIES Aluminum Skid Plate is a straightforward DIY project. Below is an expanded guide covering everything from tool preparation to torque specs.

Required Tools & Preparation

  • Socket set (metric and standard) with extensions
  • Torque wrench (recommended range: 20–40 ft-lbs)
  • Floor jack and jack stands (safety first – never work under a vehicle supported only by a jack)
  • Breaker bar for stubborn bolts
  • Penetrating oil (like WD-40) for rusted fasteners
  • Gloves and safety glasses

Installation Steps

  1. Park on level ground and chock the wheels. Engage the parking brake.
  2. Lift the vehicle using a floor jack at the manufacturer-recommended lift points. Place jack stands under the frame rails for support.
  3. Remove any existing factory skid plate if present. This usually involves removing 6–10 bolts. Keep these bolts if they are in good condition; you may reuse them for the ARIES plate.
  4. Inspect the undercarriage for damage or excessive rust. Clean the mounting surface with a wire brush if needed.
  5. Position the ARIES skid plate under the vehicle, aligning the pre-drilled holes with the existing threaded points on the frame or crossmembers.
  6. Insert the bolts hand-tight to ensure everything aligns correctly. The ARIES kit typically includes hardened bolts and washers. Do not use power tools yet.
  7. Torque all bolts to specification using a crisscross pattern. ARIES recommends 25–30 ft-lbs for most applications, but check the included instructions for your specific vehicle model.
  8. Lower the vehicle and test for clearance by turning the steering wheel lock-to-lock. Check that the skid plate does not interfere with suspension or exhaust components.
  9. Take a test drive over a few bumps and listen for rattles. If everything is secure, you’re done.

Most installations take 45 minutes to 1.5 hours, even for first-timers. The ARIES design uses factory mounting points, so drilling or modifying the vehicle is not required.

Benefits of the ARIES Aluminum Skid Plate

Undercarriage Protection

The primary role of any skid plate is to shield vulnerable components like the oil pan, transmission, transfer case, and fuel tank from rocks, logs, and road debris. The ARIES plate covers a large area and is shaped to deflect impact away from critical parts. In off-road environments, a single rock strike can cost hundreds or thousands in repairs – the $250 plate is cheap insurance.

Improved Aerodynamics and Airflow

Many modern trucks and SUVs have a rough underbody that creates drag and turbulence. The ARIES skid plate smooths the airflow underneath the vehicle, which can reduce aerodynamic drag by up to 5–10% (depending on your vehicle). This translates to slightly improved highway fuel economy and reduced wind noise. Some drivers also report more stable high-speed handling due to less air being trapped under the chassis.

Enhanced Resale Value

A well-maintained undercarriage is a strong selling point for used vehicles. An ARIES skid plate prevents rust, dents, and scratches that can lower resale value. Buyers often perceive a skid plate as a sign that the vehicle was cared for or used for light off-roading rather than neglect.

Weight Reduction Compared to Steel

If you are considering a skid plate for off-road use, aluminum offers a significant weight advantage. For example, a full set of steel skid plates can add 100+ pounds to your vehicle, reducing acceleration and fuel economy. Aluminum plates keep the weight increase minimal – the ARIES front skid plate adds only about 18 pounds. This weight savings also reduces strain on suspension components over rough terrain.

Does the ARIES Aluminum Skid Plate Improve Power?

Let’s address the million-dollar question directly: No, a skid plate does not directly increase engine horsepower or torque. However, it can improve usable performance in several indirect ways:

  • Reduced weight = better power-to-weight ratio: Aluminum skid plates are lighter than steel, so your engine has less mass to move. While the effect is small (1–2% improvement in acceleration), every bit counts for off-roaders who carry heavy gear.
  • Improved heat dissipation: Some ARIES skid plates have slots or fins that allow hot air to escape from the engine bay. Better airflow can help maintain optimal engine temperatures, preventing power loss from heat soak.
  • Enhanced aerodynamics: A smoother underbody reduces drag, which means your engine doesn’t have to work as hard to maintain highway speeds. This can free up a few horsepower otherwise lost to air resistance.
  • Peace of mind: Knowing your undercarriage is protected allows you to push your vehicle harder on rough terrain, which could be considered a performance improvement – though it’s psychological rather than mechanical.

So while the ARIES skid plate won’t add 50 horsepower, it can make your vehicle feel more responsive and efficient, especially during highway or off-road driving.

Comparison with Other Skid Plate Brands

To help you decide, here’s how the ARIES aluminum plate stacks up against competitors:

Feature ARIES Aluminum Steel Skid Plate (e.g., Rusty's) Composite Skid Plate (e.g., RCI)
Price $250 $200–$300 $300–$500
Weight 15–20 lbs 40–50 lbs 10–15 lbs
Durability High (resists dents, no rust) Very high (can bend but rarely break) Moderate (can crack under extreme impact)
Installation Easy, bolt-on Moderate (heavy) Easy, but may require extra brackets
Noise None Can rattle if not tight None

For most overlanders, the ARIES plate offers the best balance of price, weight, and corrosion resistance. If you plan to do heavy rock crawling, a steel plate might be better, but be prepared for the extra weight.

Installation Tips for a Professional Finish

  • Use a thin layer of anti-seize compound on the bolts to prevent galvanic corrosion between aluminum and steel.
  • If your vehicle has plastic underbody covers, you may need to trim them for proper clearance. A utility knife works well.
  • For trucks with aftermarket lifts, check that the skid plate doesn’t contact the differential or steering linkage at full articulation.
  • Apply threadlocker (blue Loctite®) to bolts if you drive on washboard roads – this prevents them from backing out.

Real-World User Experience

We gathered feedback from forums and direct user reviews. On average, ARIES aluminum skid plate owners give it 4.5 out of 5 stars. Common praises include: “lightweight, easy to install, and does not rust.” One Jeep Wrangler owner noted that after three years of off-road use, the plate had only minor scratches. A Ford F-150 owner reported a 1 mpg improvement on the highway, which he attributed to the reduced drag.

The only criticism? Some users wished it came with a full coverage option for the transfer case (sold separately).

Maintenance Tips

Aluminum skid plates require minimal maintenance, but here are a few things to keep it in top shape:

  • Check bolt torque every oil change (especially after hard off-road use).
  • Clean mud and debris from behind the plate to prevent moisture trapped against metal parts.
  • Polish the plate occasionally with aluminum brightener to restore its shine and protect against oxidation.
  • If you live in a salt-belt area, consider an annual undercoating to protect chassis components behind the plate.

Frequently Asked Questions
