Upgrading your Toyota Tacoma with MetalTech skid plates is one of the smartest investments you can make for serious off-road protection. These plates safeguard critical undercarriage components—oil pan, transmission case, transfer case, and fuel tank—from rocks, stumps, and deep ruts. Whether you tackle technical trails or need peace of mind on rough forest roads, a proper installation ensures the plates stay put when you need them most. This guide delivers a detailed, step-by-step installation process, tool recommendations, torque specs, and post-install checks so your Tacoma is ready for the toughest terrain.

Why MetalTech Skid Plates?

MetalTech designs its skid plates from heavy-duty steel or aluminum (depending on the model) with precision laser cutting and CNC bending for a factory-like fit. Unlike universal options that require drilling or modification, MetalTech plates bolt directly to existing mounting points on Toyota Tacomas (model years 2016–2023, and some earlier generations with adapter kits). The plates offer full coverage of the vulnerable areas while allowing access for oil changes and routine maintenance. Their robust construction handles repeated hard impacts without denting or cracking, making them a top choice among overlanders and rock crawlers.

Tools and Materials Needed

Having the right tools on hand streamlines the job and prevents frustration mid-installation. Gather everything before you lift the truck.

  • MetalTech skid plate kit (front engine, transmission, transfer case, and fuel tank plates as per your order)
  • Socket set — 10mm, 12mm, 14mm, 15mm, 18mm sockets (1/2″ drive for larger bolts, 3/8″ for smaller ones)
  • Wrench set — combination wrenches in matching sizes, plus a 19mm for suspension crossmember bolts
  • Torque wrench — ½″ drive, capable of 20–150 ft-lbs (check kit specifications for exact values)
  • Jack and jack stands — floor jack rated for 3 tons, two heavy-duty jack stands
  • Safety glasses and gloves
  • Optional but recommended: impact wrench (saves time), pry bar or rubber mallet (to align stubborn holes), blue Loctite (thread locker), penetrating oil (for rusted bolts), and a creaper or cardboard for comfort.

Torque specification note: MetalTech provides torque values in their instruction sheet. Typical figures are 59 ft-lbs for the main mounting bolts (M12 x 1.25) and 18 ft-lbs for smaller brackets. Always verify with the included paperwork because vehicle model year can affect hardware.

Preparation Steps

Preparation is as critical as the installation itself. Skipping these steps can lead to safety hazards or poor fitment.

  • Park the Tacoma on a level concrete or asphalt surface. Avoid dirt or gravel because jack stands can sink.
  • Engage the parking brake firmly. Place wheel chocks behind the rear tires for extra safety.
  • Wear safety glasses and gloves — rust debris and sharp edges are common under the truck.
  • Clean the undercarriage around the mounting areas with a pressure washer or a stiff brush and degreaser. Mud and grime can prevent the plates from sitting flush.
  • Inspect existing skid plates (if present) for damaged bolts or stripped threads. Spray penetrating oil on all fasteners you plan to remove and let it soak for 10 minutes.
  • Remove any aftermarket lights, wiring, or accessories attached to the factory skids to avoid tangling.

Step-by-Step Installation Process

Step 1: Lift the Vehicle Safely

Position the floor jack under the front differential or front crossmember. Raise the front of the truck until the tires are about 6 inches off the ground. Place jack stands under the frame rails—never under the suspension arms or differential. Lower the vehicle onto the stands so they support the weight. Give the truck a firm shake to confirm stability before crawling underneath.

For extra clearance, lift the rear axle as well if you are installing the fuel tank skid plate at the same time.

Safety warning: Never rely on the jack alone. Always use jack stands rated for the Tacoma’s weight (curb weight ~4,000 lbs).

Step 2: Remove Existing Skid Plates (if applicable)

Many Tacomas come with thin, stamped-steel factory skid plates that offer minimal protection. Use a socket and ratchet to remove the bolts securing them. The typical factory setup has:

  • Two bolts at the front of the front skid (14mm)
  • Three bolts on each side along the frame rails (12mm)
  • Two bolts at the rear of the front skid (10mm)
  • An additional crossmember that may need partial removal for access (19mm bolts)

Set aside the factory hardware in a labeled bag — you may need it later if you sell the truck or reinstall factory parts. If bolts are rusted or hard to turn, use a breaker bar or impact wrench with the appropriate socket. Clean the mounting threads with a wire brush to remove corrosion.

Step 3: Install Brackets and Crossmembers (if supplied)

Some MetalTech kits include reinforcement brackets or new crossmembers for improved rigidity. Attach these to the frame using the supplied bolts and the torque wrench. Do not fully tighten yet — leave them loose enough to allow minor movement for final plate alignment. Follow the kit-specific instruction sheet closely because bracket placement varies between front, center, and rear kits.

Step 4: Position the MetalTech Skid Plates

Starting with the front engine skid plate (often the largest), lift it into place under the truck. Align the plate’s bolt holes with the mounting points on the frame and the brackets installed in Step 3. Enlist a helper or use a floor jack under the plate to hold it up while you start a couple of bolts by hand. Do not tighten anything yet. Repeat for the transmission and transfer case skids.

Tip for stubborn alignments: Use a pry bar or a long screwdriver through the bolt holes to shift the plate left/right or forward/backward. A rubber mallet tapped on the edge of the plate can also help seat it against the frame.

Step 5: Secure the Skid Plates

Insert all bolts for a given plate before tightening. Hand-start each bolt several turns to ensure threads catch without cross-threading. If a bolt feels gritty or binds, remove it, clean the threads, and apply a drop of blue Loctite (recommended by many off-roaders to prevent vibration loosening). Once all bolts are started, begin snugging them in a cross pattern — similar to tightening lug nuts — to pull the plate evenly against the frame.

Step 6: Torque the Bolts to Specification

Set your torque wrench to the value listed in the MetalTech instructions (commonly 40–60 ft-lbs for the main M12 bolts). Tighten each bolt in the same cross pattern to the final torque. Do not exceed the spec — over-tightening can strip frame threads or deform the brackets. After torquing, check all bolts one more time to confirm they are at spec. If your kit uses nut-serts or captive nuts, be especially careful not to apply excessive torque.

Step 7: Install Remaining Plates (Transmission, Transfer Case, Fuel Tank)

Move rearward and install the transmission and transfer case plates using the same alignment and torquing procedure. The fuel tank skid plate (if included) is usually the easiest — it bols directly to the sides of the fuel tank straps. When installing the fuel tank plate, support the tank with a jack to avoid straining the straps. Tighten the retaining nuts for the straps to 25–30 ft-lbs to prevent rattling.

Important: If your Tacoma has a factory trailer hitch or aftermarket bumper, verify the skid plates do not interfere. Slight clearancing with a grinder may be needed, but MetalTech designs usually clear most setups.

Final Checks and Post-Installation

With all plates installed, perform a thorough inspection before lowering the truck.

  • Reach under and tug each plate — they should not move or clatter. Listen for rattles by tapping the plates with a wrench. Any looseness means a bolt needs retorquing.
  • Check that all bolts are present and tight. No bolts should be missing or cross-threaded.
  • Verify clearance with the exhaust system, steering components, and suspension arms. The plates should not touch these parts when the suspension cycles.
  • Test the oil drain plug and filter access — MetalTech plates typically have dedicated cutouts or removable panels. Place the oil drain pan underneath and ensure the opening aligns with the plug.

Once satisfied, raise the truck with the jack, remove the jack stands, and lower it to the ground. Retorque the front skid mounting bolts one final time with the vehicle’s weight on the suspension — frame flex can slightly alter bolt tension. This step is often overlooked but ensures the plates remain silent on the trail.

Break-In and Maintenance

After the first off-road trip (typically 100–200 miles of dirt), recheck all skid plate bolts. The vibration and impacts can cause fasteners to settle. Retorque to spec. It is also wise to clean mud and debris from between the plates and the undercarriage after each trip — trapped moisture leads to corrosion. Use a pressure washer from a safe distance to avoid forcing grit into the bolts.

Inspect the plates for dents or deformation. MetalTech steel plates can handle moderate impacts but may need straightening if repeatedly hit hard. Aluminum plates are lighter but prone to cracking under extreme abuse. Replace any cracked sections immediately.

Common Questions and Tips

Do I Need to Lift My Tacoma?

No — MetalTech skid plates are designed to fit stock-height Tacomas. However, a small lift can make installation easier because you gain more clearance to maneuver the plates. If you do not have a lift, a 3-ton floor jack and jack stands are sufficient.

Can I Install Only the Front Plate?

Yes. Many owners start with the front engine skid because it protects the most vulnerable area. The remaining plates can be added later since they bolt independently.

Will the Plates Affect Ground Clearance?

MetalTech plates mount flush with the frame rails and actually add minimal reduction in clearance (usually less than 1/4 inch). The benefit of protection far outweighs the slight loss. Some aftermarket plates hang lower — check your kit’s profile before installing.

How Do I Access the Oil Drain if the Skid Is in Place?

Most MetalTech kits include a dedicated access panel or cutout for the drain plug. Some designs use a hinged door retained by a single bolt; others have a removable plate section. In either case, you can change oil without dropping the entire skid. Follow the manufacturer’s instructions for your specific kit.
