Best Tonneau Covers for 2020–2025 Jeep Gladiator (5 ft Bed, Trail Rail Guide)

Fit data verified September 2026 · affiliate links, no extra cost to you

The Gladiator has one 5 ft (60 in) bed. The fit question is the optional Trail Rail cargo management system — its rails sit inside the bed and change how clamp-style covers seat. The Gladiator also has a taller bed rail than most midsize trucks, so low-profile hard covers look best.

Fit gotchas for the 2020–present Jeep Gladiator

Trail Rail system: covers must state Trail Rail compatibility or you remove the rails (Torx bolts, reversible).

Removable roof means the bed is your only weatherproof storage — lockable hard covers earn their price here.

Bed rail caps are plastic — use padded clamps.

Mojave / Rubicon share the standard bed.

FAQ

Can I keep the Trail Rail system with a cover?

Only with covers listed as Trail Rail compatible. Otherwise remove the rails; keep the bolts.

Do Wrangler accessories fit the Gladiator bed?

No — the Wrangler has no bed. Only Gladiator-specific covers.

Which cover works with a bed rack?

None at the same time; choose a cover-rack combo product or a bed rack with an integrated cover.

Verdict

Budget: soft tri-fold. Best overall: hard tri-fold with Trail Rail compatibility. Premium: retractable — rare for the JT, so check stock.
