Boatside Steel & Aluminum Rocker Armor for Jeep Gladiator JT 2020+
The Gladiator's long wheelbase is its weak spot on ledges, and this boatside rocker armor is Artec Industries' answer: the highest-clearance rocker protection they make for the JT. Rather than a flat slider, the armor tucks up and inboard like a boat hull, letting the long body slide across obstacles that would hang up a conventional rail. The layered two-piece design pairs 3/16" steel guards and support brackets with 1/4" heat-treated 6061-T6 aluminum armor plating — structure where the hits land, light weight everywhere else. Everything is CNC laser cut, formed, and countersunk from factory CAD files and 3D laser scans for a precise bolt-on fit.

Fits the Jeep Gladiator JT (2020 and up) and is sold as a pair covering both sides; it can work alongside many other brands' guards or sliders, though modifications may be needed. If you want lighter, flat-face protection at a lower price, look at the JT Aluminum Rocker Armor; four-door Wrangler owners get the same boatside treatment with the JLU Boatside Steel & Aluminum Rocker Armor.

Boatside Steel & Aluminum Rocker Armor for Jeep Gladiator JT 2020+ FAQs
What makes a boatside design worth it on a Gladiator?
Wheelbase. The JT's long body hangs up on ledges more easily than a Wrangler, and a flat slider edge can catch. Boatside armor angles up and inboard like a boat hull, so the truck slides across the obstacle — it is the highest-clearance rocker protection Artec offers for the JT.
Can I keep my existing sliders or guards with this kit?
Often, yes. The armor can work with many aftermarket guards or sliders, though modifications may be necessary depending on the brand. It bolts on with the included 5/16" zinc-plated countersink fasteners and requires no welding either way.
What exactly is in the box?
A pair of boatside rocker armor assemblies covering both sides of the truck: 3/16" steel guards with support brackets, 1/4" heat-treated 6061-T6 aluminum armor plating, and the flush-fit countersink hardware. Installation instructions are provided as a PDF.
