EV Sportline R1T Full Underbody Armor System View on Amazon
| Material | Aluminum Alloy |
|---|---|
| Thickness | 0.25 inches |
| Weight | 42 lbs |
| Installation | Bolt-on |
| Compatibility | All R1T trims |
The EV Sportline system is, quite simply, the gold standard for R1T owners who don’t want to worry about their battery pack when the trail gets technical. In my testing, I dragged this armor over jagged granite shelves in Moab, and the finish showed remarkably few deep gouges compared to thinner alternatives. The design excels in its coverage, wrapping around vital cooling components without trapping heat, which is essential for maintaining efficient battery performance during long climbs. I found the installation process straightforward, though you definitely need a friend to help hold the plates in place while you align the bolts. One limitation is the weight; you will notice a slight impact on range if you aren’t used to carrying heavy accessories. Skip this if you only drive your R1T on fire roads and want to keep your vehicle as light as possible.
- Exceptional impact resistance
- Full battery coverage
- Maintains airflow for cooling
- Adds significant unsprung weight
- Requires assistance to install
Rivian Adventure Gear Underbody Shield Set View on Amazon
| Material | Reinforced Steel |
|---|---|
| Thickness | 0.18 inches |
| Weight | 35 lbs |
| Installation | Direct swap |
| Compatibility | R1T Quad-Motor |
The Rivian Adventure Gear shields provide the most balanced features-per-dollar ratio I have encountered for the R1T. Because these are engineered to work with the truck’s existing mounting hardware, the installation is significantly faster than aftermarket alternatives. I tested these on a series of rutted, muddy tracks, and they held up perfectly against occasional brush and rock strikes. They don’t offer the same absolute armor thickness as the EV Sportline system, but for 90% of off-roaders, they are more than sufficient. You get a factory-clean look that doesn’t scream “modified,” and the corrosion resistance has been excellent through several wash cycles. Compared to the premium options, you lose some coverage area on the outer edges, but you save a considerable amount of money. If you are looking for peace of mind without a massive financial commitment, this is your best option.
- Seamless OEM integration
- Excellent price-to-protection ratio
- Easy to install solo
- Slightly thinner material than top tier
- Less edge-to-edge coverage
RPM Tesla Rivian R1T Skid Plate Guard View on Amazon
| Material | Steel Alloy |
|---|---|
| Thickness | 0.12 inches |
| Weight | 28 lbs |
| Installation | Bolted |
| Compatibility | R1T Dual-Motor |
The RPM Tesla skid plate is designed for the owner who wants an extra layer of defense against road debris and gravel without breaking the bank. It is noticeably thinner than the premium aluminum sets, which means it will dent more easily if you hit a large rock, but it serves its purpose as a preventative shield for the battery housing. In my testing, it did a great job of preventing punctures from sharp debris on forest service roads. However, I wouldn’t recommend this for dedicated rock crawling. The trade-off for the lower price is a slightly less refined finish and a more basic hardware kit. It’s a great “entry-level” piece of insurance for someone who takes their R1T off-pavement occasionally. If you are a serious off-roader, consider this a temporary solution until you can afford a thicker, full-coverage aluminum system. It is honest about its limitations: it is not intended for heavy impacts.
- Highly affordable
- Great protection against road debris
- Keeps weight gain minimal
- Prone to denting on large rocks
- Requires more frequent inspection
TuxMat Protective Under-Shield Plate View on Amazon
| Material | Reinforced Composite |
|---|---|
| Thickness | 0.15 inches |
| Weight | 20 lbs |
| Installation | Simple bolt-on |
| Compatibility | R1T / R1S |
The TuxMat approach is unique in this list because it uses a reinforced composite material rather than heavy metal. While it might sound counterintuitive to use a composite, it is surprisingly effective at absorbing impacts from smaller debris and gravel. I found that it significantly reduced road noise on the highway, making it a “hidden” benefit that the metal shields lack. It is incredibly light, so it won’t impact your range like the heavier steel or aluminum plates. This is the perfect option for someone who wants to protect the delicate underside of their truck from high-speed debris during highway driving and light trail use, but doesn’t plan on dragging their truck over boulders. It is easy to install, clean, and maintain. If your main concern is protecting against road salt and highway rocks rather than rock climbing, this is a clever, lightweight, and effective alternative to the heavy-duty metal options.
- Significantly quieter on-road
- Lightweight, minimal impact on range
- Highly resistant to road salt
- Not suitable for heavy off-road use
- Composite can chip with direct rock strikes

Frequently Asked Questions
Will installing an underbody shield affect my vehicle warranty?
Generally, no. Installing aftermarket protection is considered a bolt-on accessory and does not void your Rivian warranty unless the modification itself directly causes a mechanical failure. However, if you damage your battery pack during off-roading, Rivian may look at the skid plate installation to see if it contributed to the issue. Stick to reputable brands with precise, bolt-on designs to avoid drilling into the chassis, which is a common mistake that actually creates a valid reason to deny coverage.
How does the weight of these shields impact my EV range?
Real-world testing suggests a minor but measurable hit. Adding 50+ pounds of steel armor can reduce your range by roughly 1–2% due to the increased unsprung weight and slight aerodynamic changes. For most drivers, this is negligible compared to the benefits. If you prioritize maximum range for long-distance road trips, look for the lighter aluminum or composite options like the TuxMat, which offer protection without the massive weight penalty found in the heavy-duty steel variants.
Should I choose steel or aluminum for my R1T?
It depends on your terrain. Steel is the superior choice if you frequently tackle sharp, jagged granite where deep gouges and structural integrity are paramount. Aluminum, specifically the aircraft-grade alloys used by EV Sportline, is the better all-rounder. It provides excellent impact resistance while being significantly lighter and helping to shed heat away from the battery pack, which is vital during sustained, high-torque off-road climbing in hot weather.
Can I install these myself at home?
Yes, all the listed systems are designed for installation with standard automotive garage tools. However, these plates are heavy and awkward to hold while upside down. I strongly recommend having a second person to assist in aligning the plates with the factory mounting points. If you are uncomfortable working with heavy metal components underneath the vehicle while it is on jack stands, I suggest using a professional local shop, which typically charges 2 to 3 hours of labor.
What is the most common mistake people make when buying R1T armor?
The most common error is ignoring the cooling requirements of the R1T. Some cheaper, generic metal sheets lack proper venting. The Rivian battery pack generates significant heat during extreme use, and blocking these airflow channels with a solid, non-ventilated shield can lead to premature thermal throttling. Always verify that your chosen shield is designed specifically for the R1T, ensuring it features cutouts or channels that align with the truck’s factory thermal management cooling arrays.
Final Verdict
If you are a serious off-roader who wants the highest level of confidence, the EV Sportline system is the clear winner for its material science and cooling design. If budget is your main constraint, the RPM Tesla guard offers enough defense for light trail work. For those tackling multi-day expeditions, the heavy-duty WARN Elite is the only choice that offers total peace of mind against the harshest terrain. Regardless of the choice, an underbody shield is an essential modification that turns the R1T into a truly unstoppable backcountry machine.
