GR8TOPS JTRUK Kits Transforms Your Jeep® Gladiator Into A Regular Cab

If you’ve ever wished the Jeep® Gladiator (JT) came in a classic Regular Cab configuration with a full 8-foot bed, you’re not alone—and now, thanks to GR8TOPS, your wish can become reality. The South Carolina-based Jeep conversion specialist has developed the JTRUK Truck Cab Kit, a bolt-on fiberglass cab conversion that fits 2020 to 2025 Jeep Gladiator models.

What makes the JTRUK unique is its simplicity. You don’t have to cut, weld, or modify the JT’s frame, fuel lines, brake lines, or drivetrain. Everything bolts on, and you can use Jeep’s factory Freedom Panels or aftermarket hardtop accessories. GR8TOPS designed the kit so that even a Do-It-Yourselfer (DIYer) can install it over a weekend using basic tools.

What’s Included in the GR8TOPS JTRUK Kit – 

• Molded Fiberglass Cab Back with Black or Gray Gelcoat Finish

• Four Fiberglass Cab Corners to Cover the Rear Cab and Floor Supports

• Slider Rear Window with Gasket (Windowless Option also Available)

• Speaker Pod Insert with Blank Cutouts for Customization

• LED Third Brake Light and Harness

• Epoxy Bonding kit for cab corners

• Body Seam Sealer for Bonding the Floor and Cab Back

• Mopar Freedom Panel Side Gasket

• Two Metal JTRUK Retro Emblems

• Optional Black or White Gelcoat Roof Panel, Compatible with Factory or Aftermarket Freedom Panels

The JTRUK kit replaces the rear half of the cab and converts the Gladiator into a proper Regular Cab pickup, freeing up enough length for a full 8-foot bed. While GR8TOPS doesn’t supply the bed, they offer custom mounting brackets to fit a flatbed or even a camper box.

Two DIY kit pricing options are available depending on your rear window preference:

• $4,900 for a Windowless Cab Back, Ideal for Enclosed Builds or Commercial Conversions

• $5,100 for a Four-Panel Rear Slider Window Version with a Gasket for Added Visibility and Airflow

The kit includes a molded fiberglass cab back that matches the lines of the original Jeep hardtop, a sliding rear window (with the windowed kit), corner trim panels, a third brake light with wiring harness, a soundbar-ready insert, and classic JTRUK retro emblems. The interior is finished in a durable black gelcoat, and the exterior comes in either black or gray gelcoat, ready for prep and paint.

For those looking to go all-in, GR8TOPS offers a full turnkey installation at their Lexington, South Carolina shop starting at $11,500, including the painted cab kit. And with the conversion, the Gladiator sheds some serious weight. Their test build using a 2024 Gladiator Sport dropped over 900 lbs post-conversion, giving a new curb weight of just 3,830 lbs and increasing payload capacity to over 2,400 lbs. That opens the door for commercial applications like food trucks, camper builds, or backwoods hunting rigs.

GR8TOPS even offers an overlanding add-on called the JPOD, a full camper module with climate control, a sofa bed, and off-grid amenities. Unlike the cab kit, the JPOD requires cutting the body but keeps the frame untouched.

If you own a 2020 to 2025 Gladiator and want something unique, useful, and retro-cool, the JTRUK from GR8TOPS is the kit to beat. It’s a bolt-on slice of Willys-inspired utility that brings true Regular Cab truck vibes to Jeep’s most versatile platform.
