Builders working on Jeep JL, JLU, and Gladiator JT platforms quickly run into clearance and airflow limitations in the factory wheel well design. The stock plastic inner fenders leave limited room for larger tires and restrict airflow through the engine bay, which becomes more noticeable during slow speed trail driving and rock crawling.
The Motobilt High Clearance Front Inner Fenders replace the factory plastic liners with a formed aluminum design that increases tire clearance while maintaining protection for the engine compartment. The higher clearance profile provides additional room for suspension up travel and larger tire packages, helping prevent tire interference during articulation.
The MB1243-M version adds a large center ventilation panel along with the two outer vents used in the standard design. This expanded ventilation area allows significantly more airflow through the engine bay. Improved airflow can help reduce heat buildup during low speed crawling, long trail days, and demanding off-road environments where engine bay temperatures can rise.
These inner fenders are designed specifically for builders running factory style suspension systems, including Mojave Gladiator shocks. Because the center section is vented, this version is not intended to be trimmed for coilover shock tower installations.
The aluminum panels also create a clean, customizable appearance inside the wheel well. Many builders choose to powder coat or paint the mesh and panels in contrasting colors to highlight the vented design.
Like all Motobilt products, these inner fenders were developed by builders who understand the packaging challenges inside modern Jeep engine bays and the clearance required for serious off-road use.

Frequently Asked Questions
What is the advantage of high clearance inner fenders on a Jeep JL or JT?
High clearance inner fenders create additional space inside the wheel well. This allows for larger tires and increased suspension travel without the tire contacting the inner fender during articulation.
Why does this version include a center vent panel?
The MB1243-M includes a large center mesh panel to increase airflow through the engine bay. Additional airflow can help manage engine bay heat during slow speed crawling and extended off-road driving.
Can these inner fenders be used with coilover suspension conversions?
No. Because the center section is vented, the MB1243-M version is not designed to be trimmed for coilover shock tower installations. Builders planning coilover conversions should use the MB1243-B blank version.
Do these inner fenders replace the factory plastic liners?
Yes. These aluminum panels completely replace the factory plastic inner fenders while maintaining protection from mud, debris, and rocks entering the engine bay.
Will these work with Mojave Gladiator shocks?
Yes. These inner fenders are designed to work with factory style shocks including the Mojave Gladiator suspension setup.
