This Jeep JL/JLU inner fender kit combines Savvy’s front and rear inner fenders into one complete package, giving your Jeep better protection, cleaner wheel wells, and the clearance needed for aggressive off-road builds.

What makes this kit stand out is the dual front panel design. The front portion includes both solid panels and vented panels, allowing you to choose more complete coverage or increased airflow depending on your build and driving conditions. Whether you want maximum engine bay protection or improved cooling and heat dissipation, this kit gives you both options in one package.

Built from 16-gauge CNC laser-cut aluminum, these high-clearance inner fenders for Jeep JL and JLU are designed to clear 40-inch and larger tires while helping protect the engine bay, electrical wiring, fuel lines, and rear wheel well components from rocks, mud, and trail debris. The system is lightweight, corrosion resistant, and designed for serious trail use without unnecessary bulk.

The modular and trimmable design also makes this kit a strong option for custom Jeep builds. It can be adapted for aftermarket coilovers, reservoir shocks, stock flares, aftermarket fenders, and high-clearance suspension setups. Whether your Jeep is a trail rig, crawler, overland build, or daily driver with larger tires, this Jeep Wrangler JL/JLU front and rear inner fender kit offers the flexibility and protection needed to build it right.

What's Included in This Kit

This kit bundles two separately available products into one complete front-and-rear inner fender system:

Front Inner Fender Kit (SD0026): Includes both solid panels and vented panels for the front wheel wells. 16-gauge CNC laser-cut aluminum. Designed for 40"+ tires with full suspension articulation. Optional 1.82" cutback for maximum clearance. Rivnut installation required. Trimmable for aftermarket coilovers and tall shock towers. 392 and Diesel models require washer tank relocation (sold separately).

Rear Inner Fender Kit (SD0027): 16-gauge CNC laser-cut aluminum, approximately 8.5 lbs per pair. Designed for 40"+ tires at full rear suspension articulation. Extended passenger-side coverage protects electrical wiring harnesses and fuel lines. Compatible with stock fender flares and aftermarket high-clearance setups. Optional trimming recommended for maximum clearance on big-tire builds. Inner fender acts as body trimming template when you are ready to cut.

Both components are also available separately, see the individual listings for SD0026 (front) and SD0027 (rear) if you need to replace or add one component to an existing setup.

Why Buy the Complete Kit, Front and Rear Together

On a JL or JLU running 40"+ tires with lifted suspension, the front inner fenders and rear inner fenders solve the same problem from opposite ends of the build. Buying them separately is the right approach if you are upgrading in stages. Buying them together is the right approach if you are doing the complete inner fender upgrade at once.

The Front Panel Choice, Solid vs. Vented, Both Included

The Savvy front inner fender kit includes both sets in one purchase. Run solid panels when you need maximum engine bay debris protection. Swap to vented panels when you need airflow and heat dissipation for sustained hard trail use or desert running. Both panel sets are included. No additional purchase required for either configuration.

The Rear Coverage Difference

Most rear inner fenders for the JL and JLU focus on tire clearance geometry and stop there. The Savvy rear inner fender extends additional coverage on the passenger side specifically to protect electrical wiring harnesses, fuel lines, and rear components that run through the rear wheel well area. When the factory plastic liner is removed or destroyed by trail use, those components are directly exposed to rocks, mud, and debris passing through the wheel well. Savvy's design covers them. Most competitors' designs do not.

Key Features

• Complete Front & Rear System, One Purchase: Both axles covered in a single kit. Front panels in solid and vented configurations. Rear panels with extended passenger- side component coverage. Everything needed for a complete JL/JLU inner fender upgrade at once.
• Dual Front Panel Options, Both Included: Solid panels for full engine bay protection. Vented panels for maximum airflow and cooling. No competitor includes both in one kit. Swap configurations as your use case demands.
• 40"+ Tire Clearance, Front and Rear: High-clearance geometry eliminates tire rub at full compression, full droop, and full lock on JL and JLU builds running 40-inch and larger tires. Both front and rear panels are designed and tested for this tire size range.
• Extended Rear Passenger-Side Coverage: The rear inner fenders extend coverage to protect electrical wiring harnesses, fuel lines, and rear components on the passenger side the area most competitors leave exposed when factory liners are removed.
• 16-Gauge CNC Laser-Cut Aluminum Throughout: Rust-proof, lightweight, and structurally sound across all four panels. Replaces brittle factory plastic with aluminum that handles trail abuse without cracking, warping, or collapsing. Rear pair weighs approximately 8.5 lbs.
• Modular & Trimmable:  Both front and rear panels are trimmable for aftermarket coilovers, tall shock towers, and custom suspension components. Front panels include an optional 1.82" cutback for maximum clearance on aggressive big-tire setups. Rear panels act as a body trimming template when you are ready for that step. (INSTALL INSTRUCTIONS BELOW)
• Compatible with Stock and Aftermarket Flares: Works with factory JL/JLU fender flares and aftermarket high-clearance setups for both front and rear wheel wells.
• Precision CAD-Engineered Fitment: All four panels CNC laser-cut using updated Jeep JL CAD data for exact fitment on 2-door JL and 4-door JLU models across all model years 2018–2026.
• Hardware Included: All mounting hardware for front and rear installation included in the kit.

Installation Summary, What to Know Before You Start

Front panels (SD0026): Rivnuts are required for proper mounting this is a simple step but requires a Rivnut installation tool. The optional 1.82" cutback is recommended for maximum clearance on 40"+ builds but is not required for standard bolt-on installation. 392 and Diesel JL/JLU models require the washer tank relocation kit (sold separately) before front inner fender installation.

Rear panels (SD0027): Direct bolt-on using factory mounting points no Rivnuts required. Optional trimming of the rear body is recommended for maximum clearance on 40"+ builds. The rear inner fender panel itself serves as the trimming template, showing exactly where to cut for proper fitment. No trimming is required for standard installation.

All hardware for both front and rear installation is included in this kit. Mill finish blemishes may be present on raw aluminum panels cosmetic only, no effect on fitment or performance.

Best For

• 2018–2026 Jeep JL and JLU owners who want to upgrade both front and rear inner fenders at once on a 40"+ tire build
• Builders who want both solid and vented front panel options without buying two separate front inner fender kits
• Lifted JL and JLU builds where factory plastic liners are cracking, shredding, or limiting tire clearance front and rear simultaneously
• Coilover conversion builds needing trimmable inner fenders for shock body and reservoir clearance at both axles
• Builders who want rear passenger-side wiring and fuel line protection that most competitor rear inner fenders do not provide
• 392 and Diesel JL/JLU owners who are already doing the washer tank relocation and want to complete the full inner fender upgrade in one session

Why Choose the Savvy Front & Rear Inner Fender Kit?

Many Jeep JL/JLU inner fenders only address one part of the Jeep, either front or rear, and often force you to choose between airflow and coverage. The Savvy front and rear inner fender kit solves both problems by giving you a complete inner fender solution with solid and vented front panel options plus rear wheel well protection in one kit.

For Jeep owners looking for a Jeep JL inner fender kit, Jeep JLU front and rear inner fenders, or a high-clearance aluminum fender liner package built for 40s and custom suspension setups, this system offers a strong combination of clearance, protection, airflow flexibility, lightweight strength, and custom fitment potential. It is an ideal upgrade for serious trail rigs, overland Jeeps, and clean high-performance builds.

Frequently Asked Questions

Does this kit include everything for both front and rear inner fenders?
Yes. This kit includes the complete Savvy front inner fender set (SD0026) with both solid and vented panel options and the complete rear inner fender set (SD0027). All mounting hardware is included. The only additional purchase required for 392 and Diesel models is the washer tank relocation kit.

Why do the front panels require Rivnuts?
The front inner fender panels use Rivnut fasteners for their mounting method threaded inserts installed into the panel that allow bolt attachment without welding a nut. This is a clean, strong, and repeatable mounting method. Rivnut installation requires a Rivnut installation tool, which is a simple and inexpensive hand tool available at most hardware stores. The panels cannot be properly mounted without this step.

Do the rear panels also require Rivnuts?
No. The rear inner fender panels bolt directly to factory JL and JLU mounting points using standard hardware included in the kit. No Rivnut installation required for the rear.

Are both solid and vented front panels really included?
Yes. The Savvy front inner fender kit includes both solid and vented panel sets. No competitor includes both in one purchase. You choose which configuration to run based on your conditions and use case.

Do these fit both the 2-door JL and 4-door JLU?
Yes. All panels in this kit fit the 2018–2026 Jeep Wrangler JL 2-door and JLU 4-door using updated Jeep JL CAD data for exact fitment.

My JL has a 392 or Diesel engine, what do I need?
392 and Diesel models require a windshield washer fluid tank relocation kit before front inner fender installation. That kit is sold separately. Confirm you have the correct relocation kit for your specific engine before beginning installation.

Can I buy just the front or just the rear separately?
Yes. The front inner fenders (SD0026) and rear inner fenders (SD0027) are both available as individual purchases in separate listings. This bundled kit is for builders who want both at once.

What finish do the panels ship in?
Raw aluminum. Powder coat or paint to your preferred color, or prep with Scotch-Brite or DA sand for uniform finish and leave natural. Some mill finish blemishes may be present cosmetic only.
