The Motobilt MB1243-B High Clearance Front Inner Fenders for Jeep JL, JLU, and JT are designed for builders running custom suspension systems that require additional clearance inside the front wheel wells.
Like the standard MB1243 inner fenders, these panels replace the factory plastic liners with a high-clearance aluminum design that increases tire clearance and allows greater suspension up travel while helping keep mud, rocks, and debris out of the engine bay.
The MB1243-B version is intentionally designed as a blank builder version. The center portion of the panel is left solid so it can be trimmed to clear large coilovers, shock towers, remote reservoirs, or other custom suspension components.
In addition to the blank center section, the rear mesh panel found on the standard versions has also been removed and replaced with a blank panel. This provides additional room in the rear portion of the wheel well where larger shocks or suspension components are often located.
Only the front mesh ventilation panel remains, providing airflow while still allowing builders maximum flexibility when trimming the inner fenders for custom suspension layouts.
