Armor Up Your Build: RPM Aluminum Armor for the Jeep Wrangler JKU

Armor Up Your Build: RPM Aluminum Armor for the Jeep Wrangler JKU When you’re building a Jeep Wrangler JKU for real trail use, protection matters just as much as performance. Obstacles like rocks, ledges, and tight trail lines can quickly turn a great day on the trail into expensive body damage if your rig isn’t properly armored. That’s why we’ve developed a purpose-built aluminum armor system for the 4-door Jeep Wrangler JKU specifically designed to protect vulnerable body panels while keeping weight down and trail capability high. RPM Steering and Suspension currently offers two key armor components that work together to defend your Jeep’s most exposed areas: Rear Corner Armor (this is "fenderless" armor designed for large-tire 1-ton axle rigs for incredible high clearance) and Full Length Rocker Armor. Rear Corner Armor: Protecting the Most Vulnerable Body Panels The rear corners of a Wrangler are some of the first areas to take abuse on the trail. Tight departures, steep ledges, and sliding off rocks can quickly dent or crease factory sheet metal. Our JKU Aluminum Rear Corner Armor Set is designed to shield these high-impact areas with durable aluminum plating that blends protection with a clean, trail-ready look. Key features include: • 3/16" Aluminum Construction - Thick aluminum plating provides excellent protection against trail impacts while remaining lighter than steel alternatives. • Designed Specifically for 4-Door JKU Wranglers - Precision fitment ensures proper coverage and a clean installation. • Integrated 4" Round Light Cutout - Allows you to add aftermarket lighting for improved visibility on the trail or during nighttime recovery situations. • Stainless Steel Recessed Hardware - Hardware sits flush with the armor surface, reducing the risk of snagging obstacles while delivering a clean finished look. • Bare Aluminum Finish - Ships raw so builders can paint, powder coat, or finish the armor to match their rig. Full Length Rocker Armor: Shielding Your Jeep’s Side Panels On technical trails, the rocker panels often take the brunt of contact when navigating rocks or squeezing through narrow obstacles. Without proper armor, rocker panels can easily become crushed or deformed. our JKU Aluminum Full Length Rocker Armor Set extends protection along the side of the vehicle, reinforcing the entire rocker area with the same durable aluminum construction. Key Features include: • 3/16" Aluminum Armor Panels - Provides strong protection against rock strikes and trail debris. • Full-Length Coverage - Protects the entire rocker panel area rather than just localized sections. • Stainless Steel Recessed Hardware - Flush mounting improves durability and gives the armor a refined, professional appearance. • Designed to Pair with RPM Rear Corner Armor - These rocker panels integrate seamlessly with the rear corner armor for complete side protection. • Bare Aluminum Finish - Ships uncoated, allowing owners to customize the finish to match their build. While the installation of our armor requires some commitment, the payoff is long-term protection for one of the Wrangler’s most damage-prone areas. Why Aluminum Armor? RPM’s armor system uses 3/16" aluminum instead of heavier steel for several important reasons: 1. Weight savings – Keeping unnecessary weight off your Wrangler improves suspension performance and overall handling. 2. Corrosion resistance – Aluminum naturally resists rust, making it ideal for vehicles exposed to mud, water, and harsh environments. 3. Trail durability – Thick aluminum plating still provides excellent resistance to dents and trail impacts. 4. For many Jeep builders, aluminum armor strikes the ideal balance between strength, weight, and longevity. Built for Serious JKU Owners RPM’s armor components are designed for Jeep owners who actually use their rigs the way Wranglers were meant to be used—on challenging trails where body protection matters. When combined, the Rear Corner Armor and Full Length Rocker Armor create a comprehensive side protection system that helps your Wrangler survive the toughest terrain without sacrificing style or weight efficiency. Ultimately, trail damage is often unavoidable, but body damage doesn’t have to be. Whether you’re building a dedicated trail rig or simply want to protect your investment, RPM’s JKU Armor System provides the durability and fitment serious off-roaders demand. And like all RPM products, these armor components are proudly made in the USA, ensuring high-quality manufacturing and materials you can trust.
