The Front Runner Slimline II Load Bed Rack Kit in brief

Front Runner makes the Slimline II Load Bed Rack Kit, and the version for the Jeep Gladiator JT is part number KRJG002T, titled "Jeep Gladiator JT" for 2019-2026. The maker says the legs fit the factory bed tracks. The line itself is listed for 2003-2026 trucks with a T-slot bed rail mount type, and it has 13 part numbers across the Ford F-150, Chevrolet Colorado / GMC Canyon, Ram 1500/2500/3500, Toyota Tacoma and Jeep Gladiator. The maker publishes no load rating, dimensions or bed length for the Gladiator part number. The only load figure in the whole line is 660 lb static, and it belongs to the OEM bed rails kit (KRTT900T), not to the Gladiator kit. The maker's truck list for the line includes the 2020-2026 Jeep Gladiator, so a current JT owner is inside the maker's range. Confirm the part number before you order.

Which part number is yours

The Slimline II is one product type, a load bed rack kit, sold under 13 part numbers. The mount changes from kit to kit. The ReTrax XR and roll top kits (KRFF029T, KRFF015T, KRCC009T and KRDR020T) take legs that fit T-slot rails already on the truck. KRFF019T, the Ford F-150 5.5' Roll Top kit, is the exception: it includes load bed tracks and the maker says drilling may be required. KRTT900T and KRJG002T use the factory bed tracks, and for the OEM bed rails kit the maker says no drilling is required. The line carries one load number: 660 lb static, on the OEM bed rails kit KRTT900T. That kit also carries a maker advisory not to load more than 150 lb (68 kg) because of factory bed track limits. The maker does not say whether the same advisory applies to the Gladiator kit, and it gives no lift height, bar width or bed length for any of the 13. The Gladiator kit names no tonneau cover or roll top, only the factory bed tracks, so the cover options that change the answer for the Ford, Colorado, Canyon and Ram kits do not apply to it.

Which Front Runner Slimline II part number is listed for the Jeep Gladiator JT?

The maker lists KRJG002T for the Jeep Gladiator JT, 2019-2026. Per the maker, the legs fit the factory bed tracks. Other part numbers in the line, such as KRTT900T for the Toyota Tacoma, are written for other trucks.

How much weight does the Slimline II hold?

The only load figure the maker gives for the line is 660 lb static, on the OEM bed rails kit, KRTT900T. That kit also carries a maker advisory not to load more than 150 lb (68 kg) because of factory bed track limits. The maker gives no load figure for the Gladiator kit.

Does the Slimline II need drilling on a Jeep Gladiator?

The maker says no drilling is required on the OEM bed rails kit, where the legs fit the factory bed tracks. The Gladiator kit KRJG002T also fits the factory bed tracks, but the maker does not repeat the no drilling statement for it. Drilling may be required only on the Ford F-150 5.5' Roll Top kit, KRFF019T.

Is there a Slimline II for a Gladiator with a tonneau cover?

The maker lists ReTrax XR and roll top kits only for Ford F-150, Chevrolet Colorado / GMC Canyon and Ram trucks. The Gladiator kit names only the factory bed tracks, so check the maker's listing before fitting the rack over a cover.
