Jeep Gladiator JT Accessories & Parts (2020–Present)

The Gladiator JT is Jeep's mid-size pickup, built from 2020 onward. It shares much of its front end and running gear with the Wrangler JL, then adds a five-foot bed — which is where most Gladiator-specific parts live.

Trail Rail changes which tonneau cover fits

This is the most important thing to check before buying a Gladiator bed cover. Jeep's factory Trail Rail cargo management system runs rails along the inside of the bed rails, and it occupies the exact space a tonneau cover needs to clamp to.

Tonneau covers are therefore sold in two versions: with Trail Rail and without Trail Rail. Ordering the wrong one means the cover will not clamp correctly. Look into your bed before ordering — if you see rails mounted along the inner bed walls, you have Trail Rail.

What carries over from the JL, and what does not

Front bumpers, grilles, headlights, lift kits and much of the interior are shared or closely related between JT and JL. Everything from the cab back is Gladiator-only: bed covers, bed liners and mats, bed racks, tailgate accessories and the rear bumper.

Common questions

Will a Wrangler JL rear bumper fit a Gladiator? No. The JT has a different rear end and a bed, so rear bumpers are Gladiator-specific.

What bed length does the Gladiator have? Five feet. Bed covers, mats and liners are sized for that bed, so a truck cover from another platform will not fit.

Do JL lift kits fit a Gladiator? Some manufacturers make Gladiator-specific kits because the JT is longer and carries load differently. Always order the kit that lists Gladiator or JT fitment rather than assuming a JL kit transfers.

Are Gladiator and Wrangler doors interchangeable? The four-door Gladiator shares its door openings with the JLU, so many door-related parts carry over. Bed and tailgate parts never do.

Not sure it fits?
