The Baja Designs 447664UP is an eight-light linkable roof bar for the Jeep Wrangler JL and Gladiator JT, built on the brand's XL Linkable system. The manufacturer's listing covers Gladiator 2020-2026 and Wrangler JL 2018-2026, excluding Rubicon 392, Mojave, and 4xE models. The aluminum links and pre-load support bracket are meant to keep the bar rigid on rough terrain, which matters because a roof-mounted bar that flexes or vibrates on the trail loses aim and can loosen its hardware. Each light pitches up to 45 degrees vertically, and horizontal aiming is independent per light, so you can set straight or arced configurations that follow your roofline. The 447664UP is the upfitter-harness version for buyers who want to use a factory upfitter switch rather than a standalone toggle. Confirm your vehicle's switch provisions before ordering, since harness choice is the main fitment decision for this SKU. Long-tail searches this kit answers include Wrangler JL 8XL roof bar upfitter wiring, JT Gladiator linkable roof light bar, and roof light bar pre-load bracket.
The bar is rated at 208 watts, with eight XL Sport lights, a clear multi-pattern lens, and black rock guards that protect the lenses from trail debris. Compared with a cheaper bar that uses a single fixed bracket, the vehicle-specific mounting brackets and pre-load kit spread the load across the mounting points, a setup the manufacturer designed to hold up on the most extreme terrain. Owners on user forums commonly note that the roof bar adds wind noise at highway speeds, which the manufacturer also warns about, so factor that in if you drive long distances with the bar installed. The manufacturer provides an installation sheet for this kit, which should be reviewed before you start, so you know the bracket sequence and wiring path for your specific vehicle.
No. The manufacturer states that this roof bar does not fit Mojave, 392, or 4xE models, so check your trim before ordering.
The manufacturer offers the kit with either an on/off toggle harness or an upfitter harness for models with factory upfitter switch provisions. The 447664UP SKU is the upfitter-harness version.
Yes. The manufacturer warns that installing any roof-mounted lights adds a degree of wind noise, depending on the vehicle and other installed accessories.
The manufacturer publishes an installation sheet for this kit, and it is the primary reference for the bracket sequence, pre-load bracket placement, and wiring route. Before you begin, confirm that your vehicle has the upfitter switch provisions if you plan to use the upfitter harness, since the wiring path differs from the toggle setup. Owners on user forums frequently report that the wind noise from the bar is the main downside after installation, so test the bar on a highway drive before committing to a permanent setup. Tool requirements, torque specifications, and install time were not confirmed in this research, so review the manufacturer's sheet for those details.
