JT Boatside Steel & Aluminum Rocker Armor

The JT Boatside Steel & Aluminum Rocker Armor is Artec Industries' highest-clearance rocker protection for the Jeep Gladiator JT. Instead of a flat slider, the boatside profile tucks the armor up and in like a boat hull, so the JT's long body slides over ledges instead of hanging up on them. A two-piece layered build pairs 3/16" steel guards and brackets with 1/4" heat-treated 6061-T6 aluminum plating — strength where it takes the hit, light weight where it counts.

Key Features

• High-clearance "boatside" geometry angles the armor inboard for maximum ground clearance along the rockers
• 3/16" steel guards and support brackets carry the structural load
• 1/4" 6061-T6 heat-treated aluminum armor plating sheds weight without giving up protection
• 5/16" zinc-plated steel countersink fasteners sit flush for a clean, snag-free face
• Two-piece layered construction, CNC laser-cut, formed, and countersunk
• Engineered from factory CAD files and 3D laser scans for a precise bolt-on fit

Fitment & Compatibility

Fits the Jeep Gladiator JT (2020 and up). Sold as a pair to cover both sides of the vehicle. It bolts on with no welding required and can coexist with many aftermarket guards or sliders, though modifications may be necessary depending on the brand. If you want a simpler flat-face slider instead, see the standard JT aluminum option below.

Frequently Asked Questions

Does this fit my Gladiator?
Yes, it is built for the Jeep Gladiator JT (2020 and up) and sold as a pair for both sides.

What makes it a "boatside" design?
The armor is angled up and inboard like a boat hull, giving Artec's highest rocker clearance so the body slides over obstacles rather than catching on a flat slider edge.

Do I need to weld anything?
No. It is a bolt-on design. It can work alongside many aftermarket guards or sliders, though some brands may require minor modification.

Why mix steel and aluminum?
The 3/16" steel guards and brackets handle the structural impact load, while the 1/4" 6061-T6 aluminum plating keeps overall weight down — strong where it needs to be, light everywhere else.

How is this different from the standard JT rocker armor?
The boatside version prioritizes clearance and layered steel-and-aluminum protection. If you want a lighter, lower-cost flat-face guard, look at the JT Aluminum Rocker Armor.
