Common Questions
What is the Mopar Truck Bed Rail System and do I already have it?
The Mopar Truck Bed Rail System (Part #82215956) is a factory or dealer-installed accessory rail that runs along the top of the Gladiator bed walls. It is the mounting base this rack bolts to. Not all Gladiators come equipped with it from the factory. Check your bed for the rail system before ordering — if it is not present, order Mopar Part #82215956 separately before purchasing this rack.
Can I still use my bed for cargo when the rack is installed?
Yes. The removable top cross members can be taken off when you need to transport taller items in the bed. The fixed sides remain in place. The rack is also compatible with rail mount roll-up tonneau covers, giving you the option to cover the bed while the rack is installed.
What is the difference between the Basic and Deluxe rack?
Side configuration only. The Basic (RK-100-JT1) uses fixed sides for standard gear mounting. The Deluxe (RK-200-JT1) uses flip-up sides for easier access to the bed from the side. Both use the same 11-gauge steel construction, same Mopar rail requirement, and same removable cross members.
Can I add accessories to the Basic rack later?
Yes. Rock Slide Engineering offers multiple add-on accessories including side rails (RK-103-JT1) for additional gear mounting near the rear quarter panels. The modular design allows the rack to be expanded over time.
The Obsidian Take
The Overland Basic Rack (RK-100-JT1) is for the Gladiator owner who wants a clean, organized gear platform in the bed without permanent modification — 11-gauge steel, factory rail mount, removable cross members, rear grab handles, tonneau compatible. The correct choice for daily drivers and weekend overlanding rigs that need organized bed storage without the flip-up side access of the Deluxe.
One mandatory pre-order check: confirm your Gladiator has the Mopar Truck Bed Rail System (Part #82215956). That check is everything. If it is not installed, order it first. If it is already there, this rack drops in.
