Savvy Offroad High Clearance Aluminum Front & Rear Inner Fender Kit | 2007–2018 Jeep Wrangler JK / JKU

The Savvy Offroad High Clearance Aluminum Front & Rear Inner Fender Kit is the complete inner fender solution for the 2007–2018 Jeep Wrangler JK and JKU both axles, front and rear, in a single purchase. Built from 16-gauge CNC laser-cut aluminum throughout, this kit includes vented front inner fenders for maximum airflow and cooling during hard trail use, high- clearance rear inner fenders with extended coverage protecting your fuel lines, electrical wiring, and rear components from trail debris, and a trimmable one-piece design on the front panels that accommodates coilover conversions and tall shock towers. Designed for 35"– 42" tires, compatible with stock and aftermarket fender flares, and built for the JK/JKU platform that has been working harder than any Jeep ever built since 2007. Made in the USA.

What makes this kit stand out is the dual front panel design. The front portion includes vented aluminum panels for improved airflow and cooling, along with solid panel options for additional coverage depending on your build and preferences. Whether you want maximum engine bay protection or improved under-hood airflow during hard trail use, this kit gives you flexible front inner fender options in one package.

What's Included in This Kit

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

Front Inner Fenders (SD0040): Solid & Vented panels, one-piece 16-gauge CNC laser-cut aluminum panels for the front wheel wells. The integrated vented design improves airflow into the engine bay to reduce under-hood temperatures during sustained hard trail use a functional benefit for JK builds that run hard in desert heat or sustained rock crawling conditions where the factory airflow path through the wheel wells was part of how Jeep managed engine bay cooling. Trimmable for aftermarket coilover towers and remote reservoir shocks. Designed for 35"– 42" tire clearance. Ships raw aluminum minor mill blemishes may be present, easily prepped with Scotch-Brite or da sand for even finish if leaving raw.

Rear Inner Fenders (SD0041): 16-gauge CNC laser-cut aluminum rear inner fenders with high-clearance geometry for 35"– 42" tire builds. Extended coverage protects fuel lines, electrical wiring harnesses, and rear components from rocks, mud, and trail debris. Compatible with factory fender flares and aftermarket high-clearance setups. Covers exposed factory sheet metal for a clean, finished wheel well appearance. Inner fender panel acts as body trimming template when you are ready to cut for maximum clearance.

Both components are also available separately see individual listings for SD0040 (front) and SD0041 (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 JK or JKU running 35"– 42" tires with lifted suspension, the front inner fenders and rear inner fenders solve the same problem from opposite ends of the build. Here are three specific reasons to do both at once rather than in stages.

Factory plastic fails simultaneously front and rear. On a high-mileage JK that has been running big tires, the factory plastic liners are typically in the same condition at both axles degraded, shredded, or already gone. Replacing both at once completes the protection rather than leaving one axle still exposed.

One installation session. Installing inner fenders front and rear simultaneously means one lift session, one session of wrestling with fasteners, one set of tool changes, and one opportunity to do the optional trimming if your build calls for it. Doing it twice in separate sessions doubles the labor for the same end result.

The vented front and protected rear work as a system. Running vented front panels for engine bay cooling is most effective when the rear wheel well is also properly lined and not generating a separate debris intrusion path from behind. The complete kit gives you the full system working together rather than half a solution.

Key Features

• Complete Front & Rear System, One Purchase: Both axles covered in a single kit. Vented front panels for cooling alongside clearance. High-clearance rear panels with extended component coverage. Everything needed for a complete JK/JKU inner fender upgrade at once.
• Vented Front Panels, Cooling & Clearance Together: Vented panel design retains the engine bay airflow path removed by solid panel designs. Reduces under-hood temperatures during sustained hard trail use. 40"– 42" tire clearance at full compression, full droop, and full lock.
• 40"– 42" Tire Clearance, Front and Rear: High-clearance geometry eliminates tire rub on JK and JKU builds running 40 to 42 inch tires. Both front and rear panels designed and tested for this tire size range with full suspension articulation.
• Extended Rear Component Coverage: The rear inner fenders protect fuel lines, electrical wiring harnesses, and rear components from rocks, mud, and trail debris. On a high-mileage JK where these components have been exposed to trail conditions for years, restoring this coverage is a practical necessity as much as an upgrade.
• 16-Gauge CNC Laser-Cut Aluminum Throughout: Rust-proof, lightweight, and structurally sound across all panels. Replaces brittle factory plastic with aluminum that handles trail abuse without cracking, warping, or deteriorating over time.
• Trimmable Front One-Piece Design: The front inner fender panels are trimmable for aftermarket coilover conversions and tall shock towers. Trim where you need clearance, leave the rest intact.
• Clean Finished Wheel Well Appearance: Rear inner fenders cover exposed factory sheet metal for a clean, professional wheel well appearance. On a JK where the factory liner has been removed or destroyed, this restores the finished look the wheel well had from the factory.
• Compatible with Stock and Aftermarket Flares: Works with factory JK/JKU fender flares and aftermarket high-clearance setups for both front and rear wheel wells.
• Hardware Included: All mounting hardware for front and rear installation included in the kit.
• Ships Raw Aluminum: Powder coat or paint to match your build. Raw aluminum can be prepped with Scotch-Brite and left natural. Minor mill finish blemishes may be present cosmetic only. DA sand for uniform finish.
• Made in the USA: CNC laser-cut using updated Jeep JK CAD models for exact fitment across all 2007–2018 JK and JKU models.

• JK and JKU owners who want to restore clean, protected wheel wells on a platform that has been in service long enough to need it

Why Choose the Savvy Front & Rear Inner Fender Kit?

Many Jeep JK/JKU inner fenders only address one part of the Jeep, either front or rear, and often force you to choose between airflow, protection, and appearance. The Savvy front and rear inner fender kit solves all three by giving you a complete inner fender solution with front vented and solid panel options plus high-clearance rear protection in one kit.

For Jeep owners looking for a Jeep JK inner fender kit, Jeep JKU front and rear inner fenders, or a high-clearance aluminum fender liner package built for 40s and 42s, this system offers a strong combination of clearance, protection, airflow, 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 (SD0040) vented & solid panels and the complete rear inner fender set (SD0041). All mounting hardware is included.

Do these fit both the 2-door JK and 4-door JKU?
Yes. All panels in this kit fit the 2007–2018 Jeep Wrangler JK 2-door and JKU 4-door using updated Jeep JK CAD data for exact fitment across all model years.

Do the front panels require any cutting for installation?
No cutting is required for standard bolt-on installation. The one-piece design is trimmable for aftermarket coilover towers and remote reservoir shocks when that clearance is needed. Trim where needed, leave the rest intact.

Do the rear panels require trimming?
No trimming is required for standard installation. For maximum clearance on 40"– 42" tire builds, optional body trimming is recommended and the rear inner fender panel itself serves as the trimming template, showing exactly where to cut. No guesswork required.

Can I buy just the front or just the rear separately?
Yes. The front inner fenders (SD0040) and rear inner fenders (SD0041) 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 and leave natural or DA sand for uniform finish. Minor mill finish blemishes may be present on raw panels cosmetic only and normal for raw aluminum.

My JK has been running big tires for years and the factory liners are destroyed  is this the right upgrade?
Yes. This is exactly the scenario these panels are designed for. 16-gauge aluminum will not shred, crack, or deteriorate the way factory plastic does under sustained big-tire trail use. For a high-mileage JK that has already lost its factory liners, these panels restore component protection with a material that will last for the remaining life of the platform.
