JLU/JT Ultimate Clearance Front Inner Fender Liner (392/Diesel)

Making room for larger tires is only half the job. The liner still needs to cover the engine bay, and the components behind it determine how much room we have to work with. We shaped these liners specifically for the 392 and EcoDiesel, working around factory components while keeping wheel-well clearance and engine-bay coverage at the center of the design.

The two applications share the same passenger-side battery box, which lets us use the same liner for both. The 392 has one additional detail to address: a pump on the driver side needs to move, so we designed a bracket to relocate it. Those are the details we focus on—getting the most clearance possible for each specific application instead of making one generic liner fit everything.

Once the factory plastic is gone, the liner becomes part of how the finished wheel well looks. We form the main panels from .090-inch 5052 aluminum and TIG weld the main body sections in our facility in Kiowa, Colorado. The bends and welded joints create the finished shape, without asking you to build those sections by bolting individual panels together at every seam. That fabrication is part of the product you’re buying, not another job waiting for you during installation.

To make installation easier, we split each front liner into two sections. Each section can be positioned separately before they’re joined on the Jeep, allowing a tighter fit around the factory components and greater engine-bay coverage. The split serves a purpose: it lets us shape the liner for where it needs to sit without making you maneuver the entire assembly into place at once.
