How thick is the TRD skid plate?
The TRD skid plate is typically around 4.8 millimeters thick (about 3/16 of an inch), though the exact thickness varies by model and year.
TRD skid plates protect vital underbody components during off-road use, and official specifications aren’t always published for every variant. In practice, thickness depends on the specific TRD model (such as Tacoma, 4Runner, Tundra, or Sequoia) and production revision, as well as whether the plate is a steel OEM piece or an alloy accessory. This article summarizes commonly observed ranges and how to verify the exact figure for your vehicle.
Model-by-model thickness overview
Below is a rough guide to typical OEM TRD front skid plate thickness by model. Remember that official numbers can change and regional versions may differ; always verify with Toyota's parts catalog for your VIN.
- Tacoma TRD Pro front skid plate: commonly about 4.8–6.0 mm (roughly 3/16" to 1/4").
- 4Runner TRD Pro front skid plate: typically in the same ballpark, about 4.8–6.0 mm.
- Tundra TRD Pro front skid plate: usually around 4.8–6.0 mm.
- Sequoia TRD Pro front skid plate: generally 4.8–6.0 mm.
Notes: These ranges reflect typical OEM configurations and revisions; exact thickness can vary by production year and market. For precise measurement, consult the official Toyota parts catalog or your dealer with your VIN.
Why thickness matters
The thickness of a skid plate balances protective strength with weight and approach clearance. Thicker plates offer better resistance to rocks and impacts but add weight and can marginally affect ground clearance. OEM TRD plates are designed to protect engine and underbody components while maintaining off-road capability; aftermarket options often come in a wider range of gauges depending on intended use.
How to verify the exact thickness for your vehicle
- Check the official Toyota parts catalog or contact your dealer for your VIN; the diagram will show the plate specification.
- Look up the exact part number for your TRD skid plate; the datasheet typically lists thickness in millimeters.
- If you can access the plate, measure its thickness with a caliper at a flat, unpainted section away from mounting hardware.
Consulting the official catalog is the most reliable way to confirm the precise measurement for your vehicle configuration.
Summary
Across Toyota's TRD lineup, skid-plate thickness typically sits around 4.8 millimeters (about 3/16 inch), with common ranges extending toward 6 millimeters (1/4 inch) depending on model year and revision. For the exact figure on your vehicle, refer to the official Toyota parts catalog or your local dealer using your VIN.
