Underbody Armor 101: Why We Trust Rival 4x4

Underbody Armor 101: Why We Trust Rival 4x4

Taking your vehicle off-roading without a skid plate is the automotive equivalent of a hockey goalie in the 60s: no face mask, full confidence, zero protection from what’s coming next. You might survive, but the impact hurts a lot more than it needs to.

Typically, when shopping for your 4WD, you want to see the progress after spending the cash. New wheels, a fresh lift, or a rooftop tent deliver instant gratification the moment you pick up your vehicle. Skid plates and vehicle protection, on the other hand, are often overlooked because they do not offer that same visual payoff. But while underbody protection isn’t flashy, it’s arguably one of the most important upgrades you can make if you plan on going off-road. Skids and armor protect your drivetrain and shield your vehicle’s most vulnerable components.

Skid plates are typically made from plastic, aluminum, or steel. At OK4WD, we prefer either Boron steel or aluminum, depending on how and where you are off-roading. Some argue that aluminum can get hung up more easily on obstacles since it’s a softer metal. That tradeoff comes with real advantages though as aluminum is lightweight and won’t rust.


RIVAL 4x4 really sets themselves apart with their attention to detail on their skid plates and vehicle protection. Many skid plates make routine maintenance more difficult than it needs to be. Fluid changes, filter access, and basic servicing often require removing entire panels. Rival, on the other hand, has integrated oil and filter access ports for easy maintenance without having to remove the skid plate at all. They also have drainage and airflow slots for cooling and debris management. Everything is thoughtfully engineered so protection doesn’t come at the cost of usability.

Their formed aluminum skid plates are engineered specifically for real-world off-road use and offer a huge range of coverage across many vehicle platforms. While some companies cut corners with thinner steel or cheap sheet aluminum, Rivals skids are approximately 30% lighter than traditional steel skids and are made from marine-grade aluminum alloy, making them non-corrosive and ideal for long-term use in harsh environments. A zinc primer and metallic silver powder coat protect from oxidation while maintaining that clean finished look.

So yes, they are great skids, but why has OK4WD decided to add them to their trusted line up of products? The answer is simple. Unlike some aftermarket brands that are hobby projects at best, RIVAL has a real engineering pedigree. They’ve been designing aluminum armor since 2013 and are an OEM supplier for brands like Toyota and INEOS. That means they build parts that meet high manufacturing and quality standards, the type of work major manufacturers trust on production vehicles.

At the end of the day, skid plates may not be the most exciting upgrade on your build. You won’t get a double take at the gas station, or a bunch of Instagram likes. But when you hear the unmistakable sound of rock meeting the metal of your undercarriage, you’ll be very glad they are there. Quality armor doesn’t just protect your vehicle, it protects your trip experience, your wallet, and your sanity. And trust us, replacing skids is a lot easier and cheaper than replacing drivetrain components.
